PCI/ASPM: Add sysfs attributes for controlling ASPM link states
Add sysfs attributes to Endpoints and other Upstream Ports to control ASPM, Clock PM, and L1 PM Substates. The new attributes are: /sys/devices/pci*/.../link/clkpm /sys/devices/pci*/.../link/l0s_aspm /sys/devices/pci*/.../link/l1_aspm /sys/devices/pci*/.../link/l1_1_aspm /sys/devices/pci*/.../link/l1_2_aspm /sys/devices/pci*/.../link/l1_1_pcipm /sys/devices/pci*/.../link/l1_2_pcipm An attribute is only visible if both ends of the Link leading to the device support the state. Writing y/1/on to the file enables the state; n/0/off disables it. These attributes can be used to tune the power/performance tradeoff for individual devices.

block: add iostat counters for flush requests
Requests that triggers flushing volatile writeback cache to disk (barriers) have significant effect to overall performance. Block layer has sophisticated engine for combining several flush requests into one. But there is no statistics for actual flushes executed by disk. Requests which trigger flushes usually are barriers - zero-size writes. This patch adds two iostat counters into /sys/class/block/$dev/stat and /proc/diskstats - count of completed flush requests and their total time.

watchdog: make nowayout sysfs file writable
It can be useful to delay setting the nowayout feature for a watchdog device. Moreover, not every driver (notably gpio_wdt) implements a nowayout module parameter/otherwise respects CONFIG_WATCHDOG_NOWAYOUT, and modifying those drivers carries a risk of causing a regression for someone who has two watchdog devices, sets CONFIG_WATCHDOG_NOWAYOUT and somehow relies on the gpio_wdt driver being ignorant of that (i.e., allowing one to gracefully close a gpio_wdt but not the other watchdog in the system). So instead, simply make the nowayout sysfs file writable. Obviously, setting nowayout is a one-way street.

ima: Check against blacklisted hashes for files with modsig
Asymmetric private keys are used to sign multiple files. The kernel currently supports checking against blacklisted keys. However, if the public key is blacklisted, any file signed by the blacklisted key will automatically fail signature verification. Blacklisting the public key is not fine enough granularity, as we might want to only blacklist a particular file. This patch adds support for checking against the blacklisted hash of the file, without the appended signature, based on the IMA policy. It defines a new policy option "appraise_flag=check_blacklist". In addition to the blacklisted binary hashes stored in the firmware "dbx" variable, the Linux kernel may be configured to load blacklisted binary hashes onto the .blacklist keyring as well. The following example shows how to blacklist a specific kernel module hash. $ sha256sum kernel/kheaders.ko 77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 kernel/kheaders.ko $ grep BLACKLIST .config CONFIG_SYSTEM_BLACKLIST_KEYRING=y CONFIG_SYSTEM_BLACKLIST_HASH_LIST="blacklist-hash-list" $ cat certs/blacklist-hash-list "bin:77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3" Update the IMA custom measurement and appraisal policy rules (/etc/ima-policy): measure func=MODULE_CHECK template=ima-modsig appraise func=MODULE_CHECK appraise_flag=check_blacklist appraise_type=imasig|modsig After building, installing, and rebooting the kernel: 545660333 ---lswrv 0 0 \_ blacklist: bin:77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 measure func=MODULE_CHECK template=ima-modsig appraise func=MODULE_CHECK appraise_flag=check_blacklist appraise_type=imasig|modsig modprobe: ERROR: could not insert 'kheaders': Permission denied 10 0c9834db5a0182c1fb0cdc5d3adcf11a11fd83dd ima-sig sha256:3bc6ed4f0b4d6e31bc1dbc9ef844605abc7afdc6d81a57d77a1ec9407997c40 2 /usr/lib/modules/5.4.0-rc3+/kernel/kernel/kheaders.ko 10 82aad2bcc3fa8ed94762356b5c14838f3bcfa6a0 ima-modsig sha256:3bc6ed4f0b4d6e31bc1dbc9ef844605abc7afdc6d81a57d77a1ec9407997c40 2 /usr/lib/modules/5.4.0rc3+/kernel/kernel/kheaders.ko sha256:77fa889b3 5a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 3082029a06092a864886f70d010702a082028b30820287020101310d300b0609608648 016503040201300b06092a864886f70d01070131820264.... 10 25b72217cc1152b44b134ce2cd68f12dfb71acb3 ima-buf sha256:8b58427fedcf8f4b20bc8dc007f2e232bf7285d7b93a66476321f9c2a3aa132 b blacklisted-hash 77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 Signed-off-by: Nayna Jain <nayna@linux.ibm.com> [zohar@linux.ibm.com: updated patch description] Signed-off-by: Mimi Zohar <zohar@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/1572492694-6520-8-git-send-email-zohar@linux.ibm.com |

x86/bugs: Add ITLB_MULTIHIT bug infrastructure
Some processors may incur a machine check error possibly resulting in an unrecoverable CPU lockup when an instruction fetch encounters a TLB multi-hit in the instruction TLB. This can occur when the page size is changed along with either the physical address or cache type. The relevant erratum can be found here: https://bugzilla.kernel.org/show_bug.cgi?id=205195 There are other processors affected for which the erratum does not fully disclose the impact. This issue affects both bare-metal x86 page tables and EPT. It can be mitigated by either eliminating the use of large pages or by using careful TLB invalidations when changing the page size in the page tables. Just like Spectre, Meltdown, L1TF and MDS, a new bit has been allocated in MSR_IA32_ARCH_CAPABILITIES (PSCHANGE_MC_NO) and will be set on CPUs which are mitigated against this issue.

thunderbolt: Add support for lane bonding
Lane bonding allows aggregating two 10/20 Gb/s (depending on the generation) lanes into a single 20/40 Gb/s bonded link. This allows sharing the full bandwidth more efficiently. In order to establish lane bonding we need to check that lane bonding is possible through link controller and that both ends of the link actually supports 2x widths. This also means that all the paths should be established through the primary port so update tb_path_alloc() to handle this as well. Lane bonding is supported starting from Falcon Ridge (2nd generation) controllers. We also expose the current speed and number of lanes under each device except the host router following similar attribute naming than USB bus. Expose speed and number of lanes for both directions to allow possibility of asymmetric link in the future. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> |

platform/mellanox: Add bootctl driver for Mellanox BlueField Soc
This commit adds the bootctl platform driver for Mellanox BlueField
Soc, which queries secure state and controls the eMMC boot partition
swapping by sending SMC calls to ATF running at EL3.
Below are the sequences of typical use case.
1. User requests boot partition swapping, which could be on-demand or
during boot-image upgrade via UEFI capsule;
2. This bootctl driver handles the request and sends SMC call
to ATF. ATF programs register BREADCRUMB0 which has value
preserved during warm reset. It also programs eMMC to swap
the boot partition;
3. After software reset (rebooting), ATF BL1 (BootRom) checks
register BREADCRUMB0 and enable watchdog if configured;
4. If booting fails, the watchdog timer will trigger rebooting.
In such case, ATF Boot ROM will switch the boot partition
back to the previous one. This is a robust feature and used
to prevent failure during boot partition upgrade.

First set of IIO new device support, cleanups and features for the 5.5 cycle
Third version with the adis rework set dropped as better to just have
a fresh version of that at some future date.
The usual mixed backs of new device support being added to drivers,
long term reworks continuing and little per driver cleanups and
features.
Also a few trivial counter subsystem tidy ups on behalf of William.
Core new feature
* Device label support. A long requested feature no one got around to
implementing before. Allows DT based provision of a 'label' that
identifies a device uniquely within a system. This differs from existing
'name' which is meant to be the part number.
New device support
* ingenic-adc
- Support for the JZ4770 SoC ADC including bindings.
* inv_mpu6050
- Add support for magnetometer in MPU925x parts.
Fiddly to do as this is actually a separate device sitting inside the
package, but with the master device being able to schedule reads etc.
Will only run if the auxiliary bus is not in use for any other devices.
Features
* ad7192
- Userspace calibration controls to do zero and full scale.
* st_lsm6dsx
- Enable latched interrupts by default for sensors events with related clear.
- Motion events and related wakeup source. This needed quite a bit of
refactoring as well.
Cleanups and minor features
* ad7192
- sysfs ABI docs
* ad7949
- Remove code to readback configuration word as driver never actually enabled
it.
- Fix incorrect xfer length. Not actually known to cause problems other
than wasted bus usage.
* adis16080
- Replace core mlock usage with local lock with more appropriate scope.
* adis16130
- Remove pointless mlock usage.
* adis16240
- Remove include of gpio.h as no gpio usage.
* atlas-ph-sensor
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.
* bh1750
- Fix up a static compiler warning and make the code more readable.
- yaml conversion of binding + MAINTAINERS entry.
* bmp280
- Drop a stray newline.
* cm36651
- Drop a redundant assignment
* itg3200
- Alignment cleanup.
* max31856
- Add missing of_node and parent references, useful to identify the device.

Merge tag 'iio-for-5.5a-take3' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First set of IIO new device support, cleanups and features for the 5.5 cycle
Third version with the adis rework set dropped as better to just have
a fresh version of that at some future date.
The usual mixed backs of new device support being added to drivers,
long term reworks continuing and little per driver cleanups and
features.
Also a few trivial counter subsystem tidy ups on behalf of William.
Core new feature
* Device label support. A long requested feature no one got around to
implementing before. Allows DT based provision of a 'label' that
identifies a device uniquely within a system. This differs from existing
'name' which is meant to be the part number.
New device support
* ingenic-adc
- Support for the JZ4770 SoC ADC including bindings.
* inv_mpu6050
- Add support for magnetometer in MPU925x parts.
Fiddly to do as this is actually a separate device sitting inside the
package, but with the master device being able to schedule reads etc.
Will only run if the auxiliary bus is not in use for any other devices.
Features
* ad7192
- Userspace calibration controls to do zero and full scale.
* st_lsm6dsx
- Enable latched interrupts by default for sensors events with related clear.
- Motion events and related wakeup source. This needed quite a bit of
refactoring as well.
Cleanups and minor features
* ad7192
- sysfs ABI docs
* ad7949
- Remove code to readback configuration word as driver never actually enabled
it.
- Fix incorrect xfer length. Not actually known to cause problems other
than wasted bus usage.
* adis16080
- Replace core mlock usage with local lock with more appropriate scope.
* adis16130
- Remove pointless mlock usage.
* adis16240
- Remove include of gpio.h as no gpio usage.
* atlas-ph-sensor
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.
* bh1750
- Fix up a static compiler warning and make the code more readable.
- yaml conversion of binding + MAINTAINERS entry.
* bmp280
- Drop a stray newline.
* cm36651
- Drop a redundant assignment
* itg3200
- Alignment cleanup.
* max31856
- Add missing of_node and parent references, useful to identify the device.
* sc27xx_adc
- Use devm_hwspin_lock_request_specific rather than local rolled version.
* stm32-lptimer counter
- kernel-doc warning.

USB PowerShare is a policy which affects charging via the special USB PowerShare port (marked with a small lightning bolt or battery icon) when in low power states: - In S0, the port will always provide power. - In S0ix, if usb_charge is enabled, then power will be supplied to the port when on AC or if battery is > 50%. Else no power is supplied. - In S5, if usb_charge is enabled, then power will be supplied to the port when on AC. Else no power is supplied.

Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull integrity updates from Mimi Zohar: "The major feature in this time is IMA support for measuring and appraising appended file signatures. In addition are a couple of bug fixes and code cleanup to use struct_size(). In addition to the PE/COFF and IMA xattr signatures, the kexec kernel image may be signed with an appended signature, using the same scripts/sign-file tool that is used to sign kernel modules. Similarly, the initramfs may contain an appended signature. This contained a lot of refactoring of the existing appended signature verification code, so that IMA could retain the existing framework of calculating the file hash once, storing it in the IMA measurement list and extending the TPM, verifying the file's integrity based on a file hash or signature (eg. xattrs), and adding an audit record containing the file hash, all based on policy. (The IMA support for appended signatures patch set was posted and reviewed 11 times.) The support for appended signature paves the way for adding other signature verification methods, such as fs-verity, based on a single system-wide policy. The file hash used for verifying the signature and the signature, itself, can be included in the IMA measurement list" * 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity: ima: ima_api: Use struct_size() in kzalloc() ima: use struct_size() in kzalloc() sefltest/ima: support appended signatures (modsig) ima: Fix use after free in ima_read_modsig() MODSIGN: make new include file self contained ima: fix freeing ongoing ahash_request ima: always return negative code for error ima: Store the measurement again when appraising a modsig ima: Define ima-modsig template ima: Collect modsig ima: Implement support for module-style appended signatures ima: Factor xattr_verify() out of ima_appraise_measurement() ima: Add modsig appraise_type option for module-style appended signatures integrity: Select CONFIG_KEYS instead of depending on it PKCS#7: Introduce pkcs7_get_digest() PKCS#7: Refactor verify_pkcs7_signature() MODSIGN: Export module signature definitions ima: initialize the "template" field with the default template |

mm, slab: extend slab/shrink to shrink all memcg caches
Currently, a value of '1" is written to /sys/kernel/slab/<slab>/shrink file to shrink the slab by flushing out all the per-cpu slabs and free slabs in partial lists. This can be useful to squeeze out a bit more memory under extreme condition as well as making the active object counts in /proc/slabinfo more accurate. This usually applies only to the root caches, as the SLUB_MEMCG_SYSFS_ON option is usually not enabled and "slub_memcg_sysfs=1" not set. Even if memcg sysfs is turned on, it is too cumbersome and impractical to manage all those per-memcg sysfs files in a real production system. So there is no practical way to shrink memcg caches. Fix this by enabling a proper write to the shrink sysfs file of the root cache to scan all the available memcg caches and shrink them as well. For a non-root memcg cache (when SLUB_MEMCG_SYSFS_ON or slub_memcg_sysfs is on), only that cache will be shrunk when written. On a 2-socket 64-core 256-thread arm64 system with 64k page after a parallel kernel build, the the amount of memory occupied by slabs before shrinking slabs were: # grep task_struct /proc/slabinfo task_struct 53137 53192 4288 61 4 : tunables 0 0 0 : slabdata 872 872 0 # grep "^S[lRU]" /proc/meminfo Slab: 3936832 kB SReclaimable: 399104 kB SUnreclaim: 3537728 kB After shrinking slabs (by echoing "1" to all shrink files): # grep "^S[lRU]" /proc/meminfo Slab: 1356288 kB SReclaimable: 263296 kB SUnreclaim: 1092992 kB # grep task_struct /proc/slabinfo task_struct 2764 6832 4288 61 4 : tunables 0 0 0 : slabdata 112 112 0 Link: http://lkml.kernel.org/r/20190723151445.7385-1-longman@redhat.com Signed-off-by: Waiman Long <longman@redhat.com> Acked-by: Roman Gushchin <guro@fb.com> Acked-by: Christoph Lameter <cl@linux.com> Cc: Pekka Enberg <penberg@kernel.org> Cc: David Rientjes <rientjes@google.com> Cc: Joonsoo Kim <iamjoonsoo.kim@lge.com> Cc: Michal Hocko <mhocko@kernel.org> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Shakeel Butt <shakeelb@google.com> Cc: Vladimir Davydov <vdavydov.dev@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

powerpc updates for 5.4
- Initial support for running on a system with an Ultravisor, which is software
that runs below the hypervisor and protects guests against some attacks by
the hypervisor.
- Support for building the kernel to run as a "Secure Virtual Machine", ie. as
a guest capable of running on a system with an Ultravisor.
- Some changes to our DMA code on bare metal, to allow devices with medium
sized DMA masks (> 32 && < 59 bits) to use more than 2GB of DMA space.
- Support for firmware assisted crash dumps on bare metal (powernv).
- Two series fixing bugs in and refactoring our PCI EEH code.
- A large series refactoring our exception entry code to use gas macros, both
to make it more readable and also enable some future optimisations.
As well as many cleanups and other minor features & fixups.

- thunderbolt driver updates
- misc driver updates
- coresight and intel_th hwtracing driver updates
- fpga driver updates
- extcon driver updates
- some dma driver updates

Staging/IIO driver patches for 5.4-rc1
Here is the big staging/iio driver update for 5.4-rc1.
Lots of churn here, with a few driver/filesystems moving out of staging
finally:
- erofs moved out of staging
- greybus core code moved out of staging
Along with that, a new filesytem has been added:
- extfat
to provide support for those devices requiring that filesystem (i.e.
transfer devices to/from windows systems or printers.)
Other than that, there a number of new IIO drivers, and lots and lots
and lots of staging driver cleanups and minor fixes as people continue
to dig into those for easy changes.
All of these have been in linux-next for a while with no reported

Power management updates for 5.4-rc1
- Rework the main suspend-to-idle control flow to avoid repeating
"noirq" device resume and suspend operations in case of spurious
wakeups from the ACPI EC and decouple the ACPI EC wakeups support
from the LPS0 _DSM support (Rafael Wysocki).
- Extend the wakeup sources framework to expose wakeup sources as
device objects in sysfs (Tri Vo, Stephen Boyd).
- Expose system suspend statistics in sysfs (Kalesh Singh).
- Introduce a new haltpoll cpuidle driver and a new matching
governor for virtualized guests wanting to do guest-side polling
in the idle loop (Marcelo Tosatti, Joao Martins, Wanpeng Li,
Stephen Rothwell).
- Fix the menu and teo cpuidle governors to allow the scheduler tick
to be stopped if PM QoS is used to limit the CPU idle state exit
latency in some cases (Rafael Wysocki).
- Increase the resolution of the play_idle() argument to microseconds
for more fine-grained injection of CPU idle cycles (Daniel Lezcano).
- Switch over some users of cpuidle notifiers to the new QoS-based
frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
policy notifier events (Viresh Kumar).
- Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).
- Add support for MT8183 and MT8516 to the mediatek cpufreq driver
(Andrew-sh.Cheng, Fabien Parent).
- Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
Huang).
- Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).
- Update the qcom cpufreq driver (among other things, to make it
easier to extend and to use kryo cpufreq for other nvmem-based
SoCs) and add qcs404 support to it (Niklas Cassel, Douglas
RAILLARD, Sibi Sankar, Sricharan R).
- Fix assorted issues and make assorted minor improvements in the
cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,
Gustavo Silva, Hariprasad Kelam).
- Add new devfreq driver for NVidia Tegra20 (Dmitry Osipenko, Arnd
Bergmann).
- Add new Exynos PPMU events to devfreq events and extend that
mechanism (Lukasz Luba).
- Fix and clean up the exynos-bus devfreq driver (Kamil Konieczny).
- Improve devfreq documentation and governor code, fix spelling
typos in devfreq (Ezequiel Garcia, Krzysztof Kozlowski, Leonard
Crestez, MyungJoo Ham, Gaël PORTAY).
- Add regulators enable and disable to the OPP (operating performance
points) framework (Kamil Konieczny).

Pull power management updates from Rafael Wysocki:
"These include a rework of the main suspend-to-idle code flow (related
to the handling of spurious wakeups), a switch over of several users
of cpufreq notifiers to QoS-based limits, a new devfreq driver for
Tegra20, a new cpuidle driver and governor for virtualized guests, an
extension of the wakeup sources framework to expose wakeup sources as
device objects in sysfs, and more.
Specifics:
- Rework the main suspend-to-idle control flow to avoid repeating
"noirq" device resume and suspend operations in case of spurious
wakeups from the ACPI EC and decouple the ACPI EC wakeups support
from the LPS0 _DSM support (Rafael Wysocki).
- Extend the wakeup sources framework to expose wakeup sources as
device objects in sysfs (Tri Vo, Stephen Boyd).
- Expose system suspend statistics in sysfs (Kalesh Singh).
- Introduce a new haltpoll cpuidle driver and a new matching governor
for virtualized guests wanting to do guest-side polling in the idle
loop (Marcelo Tosatti, Joao Martins, Wanpeng Li, Stephen Rothwell).
- Fix the menu and teo cpuidle governors to allow the scheduler tick
to be stopped if PM QoS is used to limit the CPU idle state exit
latency in some cases (Rafael Wysocki).
- Increase the resolution of the play_idle() argument to microseconds
for more fine-grained injection of CPU idle cycles (Daniel
Lezcano).
- Switch over some users of cpuidle notifiers to the new QoS-based
frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
policy notifier events (Viresh Kumar).
- Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).
- Add support for MT8183 and MT8516 to the mediatek cpufreq driver
(Andrew-sh.Cheng, Fabien Parent).
- Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
Huang).
- Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).
- Update the qcom cpufreq driver (among other things, to make it
easier to extend and to use kryo cpufreq for other nvmem-based
SoCs) and add qcs404 support to it (Niklas Cassel, Douglas
RAILLARD, Sibi Sankar, Sricharan R).
- Fix assorted issues and make assorted minor improvements in the
cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,
Gustavo Silva, Hariprasad Kelam).
- Add new devfreq driver for NVidia Tegra20 (Dmitry Osipenko, Arnd
Bergmann).
- Add new Exynos PPMU events to devfreq events and extend that
mechanism (Lukasz Luba).
- Fix and clean up the exynos-bus devfreq driver (Kamil Konieczny).
- Improve devfreq documentation and governor code, fix spelling typos
in devfreq (Ezequiel Garcia, Krzysztof Kozlowski, Leonard Crestez,
MyungJoo Ham, Gaël PORTAY).
- Add regulators enable and disable to the OPP (operating performance
points) framework (Kamil Konieczny).

btf: expose BTF info through sysfs
Make .BTF section allocated and expose its contents through sysfs.
/sys/kernel/btf directory is created to contain all the BTFs present
inside kernel. Currently there is only kernel's main BTF, represented as
/sys/kernel/btf/kernel file. Once kernel modules' BTFs are supported,
each module will expose its BTF as /sys/kernel/btf/<module-name> file.
Current approach relies on a few pieces coming together:
1. pahole is used to take almost final vmlinux image (modulo .BTF and
kallsyms) and generate .BTF section by converting DWARF info into
BTF. This section is not allocated and not mapped to any segment,
though, so is not yet accessible from inside kernel at runtime.
2. objcopy dumps .BTF contents into binary file and subsequently
convert binary file into linkable object file with automatically
generated symbols _binary__btf_kernel_bin_start and
_binary__btf_kernel_bin_end, pointing to start and end, respectively,
of BTF raw data.
3. final vmlinux image is generated by linking this object file (and
kallsyms, if necessary). sysfs_btf.c then creates
/sys/kernel/btf/kernel file and exposes embedded BTF contents through
it. This allows, e.g., libbpf and bpftool access BTF info at
well-known location, without resorting to searching for vmlinux image
on disk (location of which is not standardized and vmlinux image
might not be even available in some scenarios, e.g., inside qemu
during testing).
Alternative approach using .incbin assembler directive to embed BTF
contents directly was attempted but didn't work, because sysfs_proc.o is
not re-compiled during link-vmlinux.sh stage. This is required, though,
to update embedded BTF data (initially empty data is embedded, then
pahole generates BTF info and we need to regenerate sysfs_btf.o with
updated contents, but it's too late at that point).
If BTF couldn't be generated due to missing or too old pahole,
sysfs_btf.c handles that gracefully by detecting that
_binary__btf_kernel_bin_start (weak symbol) is 0 and not creating
/sys/kernel/btf at all.
v2->v3:
- added Documentation/ABI/testing/sysfs-kernel-btf (Greg K-H);
- created proper kobject (btf_kobj) for btf directory (Greg K-H);
- undo v2 change of reusing vmlinux, as it causes extra kallsyms pass
due to initially missing __binary__btf_kernel_bin_{start/end} symbols;
v1->v2:
- allow kallsyms stage to re-use vmlinux generated by gen_btf();

efi: Export Runtime Configuration Interface table to sysfs
System firmware advertises the address of the 'Runtime Configuration Interface table version 2 (RCI2)' via an EFI Configuration Table entry. This code retrieves the RCI2 table from the address and exports it to sysfs as a binary attribute 'rci2' under /sys/firmware/efi/tables directory. The approach adopted is similar to the attribute 'DMI' under /sys/firmware/dmi/tables. RCI2 table contains BIOS HII in XML format and is used to populate BIOS setup page in Dell EMC OpenManage Server Administrator tool. The BIOS setup page contains BIOS tokens which can be configured.

fpga: dfl: afu: add AFU state related sysfs interfaces
This patch introduces more sysfs interfaces for Accelerated Function Unit (AFU). These interfaces allow users to read current AFU Power State (APx), read / clear AFU Power (APx) events which are sticky to identify transient APx state, and manage AFU's LTR (latency tolerance reporting).

intel_th: msu: Introduce buffer interface
Introduces a concept of external buffers, which is a mechanism for creating trace sinks that would receive trace data from MSC buffers and transfer it elsewhere. A external buffer can implement its own window allocation/deallocation if it has to. It must provide a callback that's used to notify it when a window fills up, so that it can then start a DMA transaction from that window 'elsewhere'. This window remains in a 'locked' state and won't be used for storing new trace data until the buffer 'unlocks' it with a provided API call, at which point the window can be used again for storing trace data. This relies on a functional "last block" interrupt, so not all versions of Trace Hub can use this feature, which does not reflect on existing users.

platform/x86: asus: Rename "fan mode" to "fan boost mode"
The Asus WMI spec indicates that the function being controlled here is called "Fan Boost Mode". The user-facing documentation also calls it this. The spec uses the term "fan mode" is used to refer to other things, including functionality expected to appear on future products. We missed this before as we are not dealing with the most readable of specs, and didn't forsee any confusion around shortening the name. Rename "fan mode" to "fan boost mode" to improve consistency with the spec and to avoid a future naming conflict. There is no interface breakage here since this has yet to be included in an official kernel release. I also updated the kernel version listed under ABI accordingly.

platform-drivers-x86 for v5.3-1
ASUS WMI driver got a big refactoring in order to support the TUF Gaming laptops. Besides that, the regression with backlight being permanently off on various EeePC laptops has been fixed. Accelerometer on HP ProBook 450 G0 shows wrong measurements due to X axis being inverted. This has been fixed. Intel PMC core driver has been extended to be ACPI enumerated if the DSDT provides device with _HID "INT33A1". This allows to convert the driver to be pure platform and support new hardware purely based on ACPI DSDT. From now on the Intel Speed Select Technology is supported thru a corresponding driver. This driver provides an access to the features of the ISST, such as Performance Profile, Core Power, Base frequency and Turbo Frequency. Mellanox platform drivers has been refactored and now extended to support more systems, including new coming ones. The OLPC XO-1.75 platform is now supported. CB4063 Beckhoff Automation board is using PMC clocks, provided via pmc_atom driver, for ethernet controllers in a way that they can't be managed by the clock driver. The quirk has been extended to cover this case. Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile the information of Chuwi Hi10 Air has been fixed to cover more models based on the same platform. Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it has been provided. It required some extension of the generic WMI library, which allows to propagate opaque context to the ->probe() of the individual drivers. This release includes debugfs clean up from Greg KH for several drivers that drop return code check and make debugfs absence or failure non-fatal. Miscellaneous fixes here and there, mostly for Acer WMI and various Intel drivers. The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle: - |

f2fs-for-5.3-rc1
In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads. In addition, we've fixed subtle quota corruption issue.

Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups. Because of this, there is going
to be some merge issues with your tree at the moment, I'll follow up
with the expected resolutions to make it easier for you.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups (will cause build warnings
with s390 and coresight drivers in your tree)
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse
easier due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes
All of these have been in linux-next for a while, with a bunch of merge
issues that Stephen has been patient with me for. Other than the merge
issues, functionality is working properly in linux-next :)

mm: smaps: split PSS into components
Report separate components (anon, file, and shmem) for PSS in smaps_rollup. This helps understand and tune the memory manager behavior in consumer devices, particularly mobile devices. Many of them (e.g. chromebooks and Android-based devices) use zram for anon memory, and perform disk reads for discarded file pages. The difference in latency is large (e.g. reading a single page from SSD is 30 times slower than decompressing a zram page on one popular device), thus it is useful to know how much of the PSS is anon vs. file. All the information is already present in /proc/pid/smaps, but much more expensive to obtain because of the large size of that procfs entry. This patch also removes a small code duplication in smaps_account, which would have gotten worse otherwise. Also updated Documentation/filesystems/proc.txt (the smaps section was a bit stale, and I added a smaps_rollup section) and Documentation/ABI/testing/procfs-smaps_rollup.

Char / Misc driver patches for 5.3-rc1
Here is the "large" pull request for char and misc and other assorted smaller driver subsystems for 5.3-rc1. It seems that this tree is becoming the funnel point of lots of smaller driver subsystems, which is fine for me, but that's why it is getting larger over time and does not just contain stuff under drivers/char/ and drivers/misc. Lots of small updates all over the place here from different driver subsystems: - habana driver updates - coresight driver updates - documentation file movements and updates - Android binder fixes and updates - extcon driver updates - google firmware driver updates - fsi driver updates - smaller misc and char driver updates - soundwire driver updates - nvmem driver updates - w1 driver fixes All of these have been in linux-next for a while with no reported issues.

It's been a relatively busy cycle for docs:
- A fair pile of RST conversions, many from Mauro. These create more
than the usual number of simple but annoying merge conflicts with other
trees, unfortunately. He has a lot more of these waiting on the wings
that, I think, will go to you directly later on.
- A new document on how to use merges and rebases in kernel repos, and one
on Spectre vulnerabilities.
- Various improvements to the build system, including automatic markup of
function() references because some people, for reasons I will never
understand, were of the opinion that :c:func:``function()`` is
unattractive and not fun to type.
- We now recommend using sphinx 1.7, but still support back to 1.4.
- Lots of smaller improvements, warning fixes, typo fixes, etc.

Power management updates for 5.3-rc1
- Improve the handling of shared ACPI power resources in the PCI
bus type layer (Mika Westerberg).
- Make the PCI layer take link delays required by the PCIe spec
into account as appropriate and avoid polling devices in D3cold

IOMMU Updates for Linux v5.3
Including: - Patches to make the dma-iommu code more generic so that it can be used outside of the ARM context with other IOMMU drivers. Goal is to make use of it on x86 too. - Generic IOMMU domain support for the Intel VT-d driver. This driver now makes more use of common IOMMU code to allocate default domains for the devices it handles. - An IOMMU fault reporting API to userspace. With that the IOMMU fault handling can be done in user-space, for example to forward the faults to a VM. - Better handling for reserved regions requested by the firmware. These can be 'relaxed' now, meaning that those don't prevent a device being attached to a VM. - Suspend/Resume support for the Renesas IOMMU driver. - Added support for dumping SVA related fields of the DMAR table in the Intel VT-d driver via debugfs. - A pile of smaller fixes and cleanups. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAl0jaOAACgkQK/BELZcB GuNYTRAAjXuNs1OX/ROJ4TByT3YBWj5BLZVMrpGx75MAEvO68a7rTdaCpGuHv09w 5JneXxA3H2O1q6JCGguLm//Dy5QycJQIn0WuaBGi5Vjo+cGe47sf48Hb6AhIoAFf exjhfmG6kL3ZzEkLU/7iJWqz+iiCBxRU0yMINJvzFFzliJkfyGWsjoruxobmUEhm XdEsdeAQFXoPMNVCDiorM+B+3VCl7BfwfhdlFrmX3fpNrMZ5ytlnPTgfJdXAGgHn DAoK8qGoyYtRnZnivn1y56M13qv5y3XvicKqx/GRKK8CyJpz/vYSBLktI5HO4tOF y/VzNg+ctDSjQgFyKIq+38k6qu4YWctyxZNObmPVpioNf9j9GaZWT97fxGzXMNS4 G7TqOeq4yxjotAOcd+DdH265uVBtGmLqk7XobigxCZ0xzGVVnmPy4oJtkWwjaMgN HtNSMPRRirjprK4BUoCiXwP8YyWZs0a93oJmh2orD406yZkHNuqLNaicu24WsKKf Ze5BsFbNUb0qYdyL7ofOugQrOvYYoWYuREiz8ClF3U4mCcOk4FJ9K2Vf1kSfKBX8 1Skz75NeSZdzXg9JcznNMuiqH2mN3lx/88xKJg3LJxEeFxU++VDMX3Z8kEmpj5w+ 9m/v+VRclUXL6g8s6QFNIlIenMknAEjtWw6hVWPhWLaULH6fR6Y= =Kvk5 -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu updates from Joerg Roedel: - Make the dma-iommu code more generic so that it can be used outside of the ARM context with other IOMMU drivers.

Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull integrity updates from Mimi Zohar:
"Bug fixes, code clean up, and new features:
- IMA policy rules can be defined in terms of LSM labels, making the
IMA policy dependent on LSM policy label changes, in particular LSM
label deletions. The new environment, in which IMA-appraisal is
being used, frequently updates the LSM policy and permits LSM label
deletions.
- Prevent an mmap'ed shared file opened for write from also being
mmap'ed execute. In the long term, making this and other similar
changes at the VFS layer would be preferable.
- The IMA per policy rule template format support is needed for a
couple of new/proposed features (eg. kexec boot command line
measurement, appended signatures, and VFS provided file hashes).
- Other than the "boot-aggregate" record in the IMA measuremeent
list, all other measurements are of file data. Measuring and
storing the kexec boot command line in the IMA measurement list is
the first buffer based measurement included in the measurement
list"
* 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity:
integrity: Introduce struct evm_xattr
ima: Update MAX_TEMPLATE_NAME_LEN to fit largest reasonable definition
KEXEC: Call ima_kexec_cmdline to measure the boot command line args
IMA: Define a new template field buf
IMA: Define a new hook to measure the kexec boot command line arguments
IMA: support for per policy rule template formats
integrity: Fix __integrity_init_keyring() section mismatch
ima: Use designated initializers for struct ima_event_data
ima: use the lsm policy update notifier
LSM: switch to blocking policy update notifiers
x86/ima: fix the Kconfig dependency for IMA_ARCH_POLICY
ima: Make arch_policy_entry static
ima: prevent a file already mmap'ed write to be mmap'ed execute
x86/ima: check EFI SetupMode too

Merge branch 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 CPU feature updates from Thomas Gleixner:
"Updates for x86 CPU features:
- Support for UMWAIT/UMONITOR, which allows to use MWAIT and MONITOR
instructions in user space to save power e.g. in HPC workloads
which spin wait on synchronization points.
The maximum time a MWAIT can halt in userspace is controlled by the
kernel and can be adjusted by the sysadmin.
- Speed up the MTRR handling code on CPUs which support cache
self-snooping correctly.
On those CPUs the wbinvd() invocations can be omitted which speeds
up the MTRR setup by a factor of 50.
- Support for the new x86 vendor Zhaoxin who develops processors
based on the VIA Centaur technology.
- Prevent 'cat /proc/cpuinfo' from affecting isolated NOHZ_FULL CPUs
by sending IPIs to retrieve the CPU frequency and use the cached
values instead.
- The addition and late revert of the FSGSBASE support. The revert
was required as it turned out that the code still has hard to
diagnose issues. Yet another engineering trainwreck...
- Small fixes, cleanups, improvements and the usual new Intel CPU
family/model addons"
