Documentation: cpu-freq: Frequencies aren't always sorted
The order in which the frequencies are displayed in cpufreq stats depends on the order in which the frequencies were sorted in the frequency table provided to cpufreq core by the cpufreq driver. They can be completely unsorted as well. The documentation's claim that the stats will be sorted in descending order is hence incorrect and here is an attempt to fix it.

x86/mm: Move LDT remap out of KASLR region on 5-level paging
On 5-level paging the LDT remap area is placed in the middle of the KASLR
randomization region and it can overlap with the direct mapping, the
vmalloc or the vmap area.
The LDT mapping is per mm, so it cannot be moved into the P4D page table
next to the CPU_ENTRY_AREA without complicating PGD table allocation for
5-level paging.
The 4 PGD slot gap just before the direct mapping is reserved for
hypervisors, so it cannot be used.
Move the direct mapping one slot deeper and use the resulting gap for the
LDT remap area. The resulting layout is the same for 4 and 5 level paging.

cleanup series. It had one fix earlier for a stacked device issue, but
another one was reported. Rather than play whack-a-mole with this,
revert the entire series and try again for the next kernel release.
Apart from that, only small fixes/changes.

- The blkcg cleanup series revert (Dennis Zhou)
- Two NVMe fixes. One fixing a regression in the nvme request
initialization in this merge window, causing nvme-fc to not work.
The other is a suspend/resume p2p resource issue (James, Keith)
- Fix sg discard merge, allowing us to merge in cases where we didn't

- Call rq_qos_exit() after the queue is frozen, preventing a hang

pwm: Changes for v4.20-rc1
This series contains a number of improvements to existing drivers, such
as LPSS. Some drivers, such as renesas-tpu and rcar get support for more
SoC generations. To round things off this fixes an issue with the sysfs
interface.

vfs: rework data cloning infrastructure
Rework the vfs_clone_file_range and vfs_dedupe_file_range infrastructure to use a common .remap_file_range method and supply generic bounds and sanity checking functions that are shared with the data write path. The current VFS infrastructure has problems with rlimit, LFS file sizes, file time stamps, maximum filesystem file sizes, stripping setuid bits, etc and so they are addressed in these commits. We also introduce the ability for the ->remap_file_range methods to return short clones so that clones for vfs_copy_file_range() don't get rejected if the entire range can't be cloned. It also allows filesystems to sliently skip deduplication of partial EOF blocks if they are not capable of doing so without requiring errors to be thrown to userspace. All existing filesystems are converted to user the new .remap_file_range method, and both XFS and ocfs2 are modified to make use of the new generic checking infrastructure. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJb29gEAAoJEK3oKUf0dfodpOAQAL2VbHjvKXEwNMDTKscSRMmZ Z0xXo3gamFKQ+VGOqy2g2lmAYQs9SAnTuCGTJ7zIAp7u+q8gzUy5FzKAwLS4Id6L 8siaY6nzlicfO04d0MdXnWz0f3xykChgzfdQfVUlUi7WrDioBUECLPmx4a+USsp1 DQGjLOZfoOAmn2rijdnH9RTEaHqg+8mcTaLN9TRav4gGqrWxldFKXw2y6ouFC7uo /hxTRNXR9VI+EdbDelwBNXl9nU9gQA0WLOvRKwgUrtv6bSJohTPsmXt7EbBtNcVR cl3zDNc1sLD1bLaRLEUAszI/33wXaaQgom1iB51obIcHHef+JxRNG/j6rUMfzxZI VaauGv5EIvtaKN0LTAqVVLQ8t2MQFYfOr8TykmO+1UFog204aKRANdVMHDSjxD/0 dTGKJGcq+HnKQ+JHDbTdvuXEL8sUUl1FiLjOQbZPw63XmuddLKFUA2TOjXn6htbU 1h1MG5d9KjGLpabp2BQheczD08NuSmcrOBNt7IoeI3+nxr3HpMwprfB9TyaERy9X iEgyVXmjjc9bLLRW7A2wm77aW64NvPs51wKMnvuNgNwnCewrGS6cB8WVj2zbQjH1 h3f3nku44s9ctNPSBzb/sJLnpqmZQ5t0oSmrMSN+5+En6rNTacoJCzxHRJBA7z/h Z+C6y1GTZw0euY6Zjiwu =CE/A -----END PGP SIGNATURE----- Merge tag 'xfs-4.20-merge-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux Pull vfs dedup fixes from Dave Chinner: "This reworks the vfs data cloning infrastructure.

The Compiler Attributes series
This is an effort to disentangle the include/linux/compiler*.h headers and bring them up to date. The main idea behind the series is to use feature checking macros (i.e. __has_attribute) instead of compiler version checks (e.g. GCC_VERSION), which are compiler-agnostic (so they can be shared, reducing the size of compiler-specific headers) and version-agnostic. Other related improvements have been performed in the headers as well, which on top of the use of __has_attribute it has amounted to a significant simplification of these headers (e.g. GCC_VERSION is now only guarding a few non-attribute macros). This series should also help the efforts to support compiling the kernel with clang and icc. A fair amount of documentation and comments have also been added, clarified or removed; and the headers are now more readable, which should help kernel developers in general. The series was triggered due to the move to gcc >= 4.6. In turn, this series has also triggered Sparse to gain the ability to recognize __has_attribute on its own. Finally, the __nonstring variable attribute series has been also applied on top; plus two related patches from Nick Desaulniers for unreachable() that came a bit afterwards. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEPjU5OPd5QIZ9jqqOGXyLc2htIW0FAlvNpywACgkQGXyLc2ht IW1aiQ/+P8SJOa3GkiH37/nrIbk/wgMNytbs+gxE5YPaU1DP74Mn1prJ4XhQQic9 /mt8GnitZwzEHWdsGEUk+ZQwnIa7ZEAmpecbAF206AMRbNxa14T5YwBx4bqWFjZp sP4zPTHt3JCKL8TM+z26o152UbF2kc4WSxHjEjSFaqEnR2E5D0MwFeGPzc8fgWmS pNyn3CidzB0TS1UF008YXhiJO6HIhFNPyhPawlhwbbdsdlhZ4u0JmwfqP4EvjRFM kyzdQ9CDe+AgTTD9Y8HhtoUClaa7SJzFWNzpKIJMWt8jpKWYZQ/+WtwKg2cf+v3M uwktcs3RI1dYrjcITLz4VJ0oVaRFnyGgXvMP4yqWQx429hqnd09WXhMioXQ1htoI H0vpPIAPsK+dqVA9sP3JzMq4h6+dE7P364lkbThbVpYAGKZ52qaLt9ixT1mw1Q9f a683ji6o02IVOGUNZ/3KAb5MqdhewNEDdZILZYRfm4AL1Em3WW9QVtIosHPviLgc 16VjA02wKdxIcg+1LZMTNhfybztnSCf7SuQurpH1zEqFDGzrXwB7nYFplEY7DrrD cqhOA1fMQa++oQR+D40QDoY2ybqPOyvJG7z17pvtt+6jXep4yy2a3Bxf+ClK0nto 5yT7v9ikXJr84FOkk7OvktLlAWvcykvAdfvDepBZhpqhuX82tHY= =Y8WB -----END PGP SIGNATURE----- Merge tag 'compiler-attributes-for-linus-4.20-rc1' of https://github.com/ojeda/linux Pull compiler attribute updates from Miguel Ojeda: "This is an effort to disentangle the include/linux/compiler*.h headers and bring them up to date.

Pull keys updates from James Morris:
"Provide five new operations in the key_type struct that can be used to
provide access to asymmetric key operations. These will be implemented
for the asymmetric key type in a later patch and may refer to a key
retained in RAM by the kernel or a key retained in crypto hardware.
int (*asym_query)(const struct kernel_pkey_params *params,
struct kernel_pkey_query *info);
int (*asym_eds_op)(struct kernel_pkey_params *params,
const void *in, void *out);
int (*asym_verify_signature)(struct kernel_pkey_params *params,
const void *in, const void *in2);
Since encrypt, decrypt and sign are identical in their interfaces,
they're rolled together in the asym_eds_op() operation and there's an
operation ID in the params argument to distinguish them.
Verify is different in that we supply the data and the signature
instead and get an error value (or 0) as the only result on the
expectation that this may well be how a hardware crypto device may
work"

ovl: automatically enable redirect_dir on metacopy=on
Current behavior is to automatically disable metacopy if redirect_dir is
not enabled and proceed with the mount.
If "metacopy=on" mount option was given, then this behavior can confuse the
user: no mount failure, yet metacopy is disabled.
This patch makes metacopy=on imply redirect_dir=on.
The converse is also true: turning off full redirect with redirect_dir=
{off|follow|nofollow} will disable metacopy.
If both metacopy=on and redirect_dir={off|follow|nofollow} is specified,
then mount will fail, since there's no way to correctly resolve the
conflict.

Pull stackleak gcc plugin from Kees Cook:
"Please pull this new GCC plugin, stackleak, for v4.20-rc1. This plugin
was ported from grsecurity by Alexander Popov. It provides efficient
stack content poisoning at syscall exit. This creates a defense
against at least two classes of flaws:
- Uninitialized stack usage. (We continue to work on improving the
compiler to do this in other ways: e.g. unconditional zero init was
proposed to GCC and Clang, and more plugin work has started too).
- Stack content exposure. By greatly reducing the lifetime of valid
stack contents, exposures via either direct read bugs or unknown
cache side-channels become much more difficult to exploit. This
complements the existing buddy and heap poisoning options, but
provides the coverage for stacks.
The x86 hooks are included in this series (which have been reviewed by
Ingo, Dave Hansen, and Thomas Gleixner). The arm64 hooks have already
been merged through the arm64 tree (written by Laura Abbott and
reviewed by Mark Rutland and Will Deacon).
With VLAs having been removed this release, there is no need for
alloca() protection, so it has been removed from the plugin"

The highlights are:
- a series that fixes some old memory allocation issues in libceph
(myself). We no longer allocate memory in places where allocation
failures cannot be handled and BUG when the allocation fails.
- support for copy_file_range() syscall (Luis Henriques). If size and
alignment conditions are met, it leverages RADOS copy-from operation.
Otherwise, a local copy is performed.
- a patch that reduces memory requirement of ceph_sync_read() from the
size of the entire read to the size of one object (Zheng Yan).
- fallocate() syscall is now restricted to FALLOC_FL_PUNCH_HOLE (Luis
Henriques)

This time it looks like a quieter release cycle in the clk tree. I guess that's
because of summer time holidays/vacations. The biggest change in the diffstat is in the Qualcomm clk driver, where they got support for CPUs and handful of SoCs. After that, the at91 driver got a major rewrite for newer DT bindings that should make things easier going forward and the TI code moved to a clockdomain based design. The long tail is mostly small driver updates for newer clks and some simpler SoC clock drivers such as the Hisilicon and imx support. In the core framework, we only have two small changes this time. One is a new clk API to get all clks for a device with the bulk clk APIs. This allows drivers that don't care about doing anything besides turning on all the clks to just clk_get() them all and turn them on. The other change is the beginning of a way to support save and restore of clk settings in the clk framework. TI is the only user right now, but we will want to expand upon this design in the future to support more save and restore of clk registers. At least this gets us started and works well enough for one SoC, but there's more work in the future.

The latest versions of Google camera and codec HAL depends on such feature. At this stage, it supports only stateless codecs. It has been discussed for a long time (at least over the last 3-4 years), and we finally reached to something that seem to work. This series contain both the API and core changes required to support it and a new m2m decoder driver (cedrus). As the current API is still experimental, the only real driver using it (cedrus) was added at staging[1]. We intend to keep it there for a while, in order to test the API. Only when we're sure that this API works for other cases (like encoders), we'll move this driver out of staging and set the API into a stone.

Olga added support for the NFSv4.2 asynchronous copy protocol. We
already supported COPY, by copying a limited amount of data and then returning a short result, letting the client resend. The asynchronous protocol should offer better performance at the expense of some complexity. The other highlight is Trond's work to convert the duplicate reply cache to a red-black tree, and to move it and some other server caches to RCU. (Previously these have meant taking global spinlocks on every RPC.) Otherwise, some RDMA work and miscellaneous bugfixes. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJb2KWzAAoJECebzXlCjuG+gcQP/3DldB86CFxgSFx0t+h+s+TV CdYJDPyLyRkEMiD+4dCPPuhueve+j5BPHVsDbn98FTWrEn131NMIs6uhU/VGTtAU 6a8f/ExtZ5U7s39MJCzlk2ozVElBc3QPp7p3p9NKn0Wi0PXbVgjuIqR5o2vwa8Si KOVdLm6ylfav/HTH8DO6zFPJRsTgTwcJOivXXshjpglMKAcw8AuqSsGgBrDeGpgU u91Vi0EM1vt96+CA6a01mTgC/sFX7EqGvxUUHOrKWf5cIjnpT3FDvouYPxi+GH8Z SIDlaMQyXF5m4m6MhELNTP4v97XAHyPJtvLkEe5lggTyABPiA2heo9e8onysWkzV 1v8OZHCVFa1UL34mDlnFxbFCYVr7FFKMGjTBR/ntinobPfAbWRCO1Hdd+bBGPDD4 byf7ctDVp7KQ2bSatIdlYavikuGDHWFDZHzPHlqkD3gpIZSNvhe26sV3NZqIFlXO cMUega2Y5mXmULauHhxAcNGtDK7dF5hHoMWKJy0DNxiyDiDLylwDOIfwt1De3Q7V ycd/wUytUS2LkAhyS2mvoDK6eXTBAeQwzmXAqveh6rewwO83HC/t9mtKBBDomvKG xRpRPmmbj9ijbwkilEBmijjR47wrihmEVIFahznEerZ+//QOfVVOB0MNtzIyU9/k CnP1ZNvOs3LR1pxxwFa8 =TTo0 -----END PGP SIGNATURE----- Merge tag 'nfsd-4.20' of git://linux-nfs.org/~bfields/linux Pull nfsd updates from Bruce Fields: "Olga added support for the NFSv4.2 asynchronous copy protocol.

The biggest change here is the updates to kprobes
Back in January I posted patches to create function based events. These were
the events that you suggested I make to allow developers to easily create
events in code where no trace event exists. After posting those changes for
review, it was suggested that we implement this instead with kprobes.
The problem with kprobes is that the interface is too complex and needs to
be simplified. Masami Hiramatsu posted patches in March and I've been
playing with them a bit. There's been a bit of clean up in the kprobe code
that was inspired by the function based event patches, and a couple of
enhancements to the kprobe event interface.
- If the arch supports it (we added support for x86), you can place a
kprobe event at the start of a function and use $arg1, $arg2, etc
to reference the arguments of a function. (Before you needed to know
what register or where on the stack the argument was).
- The second is a way to see array of events. For example, if you reference
a mac address, you can add:
echo 'p:mac ip_rcv perm_addr=+574($arg2):x8[6]' > kprobe_events
And this will produce:
mac: (ip_rcv+0x0/0x140) perm_addr={0x52,0x54,0x0,0xc0,0x76,0xec}
Other changes include
- Exporting trace_dump_stack to modules
- Have the stack tracer trace the entire stack (stop trying to remove
tracing itself, as we keep removing too much).
- Added support for SDT in uprobes

remoteproc updates for v4.20
This contains a series of patches that reworks the memory carveout handling in remoteproc, in order to allow this to be reused for statically allocated memory regions to be used for e.g. firmware. It adds support for audio DSP (both TZ-assisted and non-TZ assisted) and compute DSP on Qualcomm SDM845, TZ-assisted audio DSP, compute DSP and WiFi processor on Qualcomm QCS404 and through some renaming of the drivers cleans up the naming situation. Finally support for custom coreudmp segment handlers is added and is used in the Qualcomm modem remoteproc driver to gather memory dumps of the firmware. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAlvXlhMbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FvvUP/j5M7fvB1kJnd6NUJ1Hz CKTw05eYeC4Z9d6nBIso6jcYbf6QfBwtBmdEPfa8Yzhc+Mkr91dR85ylzjd1+PXm qcCEOrofMMHQ2CSPO0dfdii4zvQRdo2CvMShJqdc/PUo0G4QPQR8Pdb6fLW5S4uL zb0K0CqS8KBzY382r6QyV5riv+8nsuTKLWTzPHL/mmXD0aW5YCVgxG56DScFJVu3 HD9YzbsECzIBuB0k1UufdYxb2FkRy2pOWttiKDQAlB2q7AxOwEV/oqWQKpmHVb2k F94zRWlttuMabjtRajDDSqfG8DUse7zpCgakk+oehEZq1WmcVfLKs+asqELBLNc7 J/3N1g2+cE+VQUqBiew6WUR6zgMFMfyqucnp8t0KRgZvpQPxfpiRqynoFxEj8MXl z4lptuk7DMhYphrwWhA+D/Jqc1prMmX7smCDou3b43DFVYZ06c2gI7aO9VPVhT4m SUFhzznTn6FUfnFWzDAuDKt51WaRIFemgvvprsNHrl24rtQhYdel+12U9ySiFq8q Z7Bqb3jNcZ6qHjLy4+6jtnQSZoyf6bbcvF2++85m16i4vElu1X1TQ6HXMmrXpBZ9 z454/jVacZ2vtiAzustBlu86QQZtQhVHenn7j34AWkqIBCF3PiHuZqVfaw0R/pZq 3/HkgfsgudLRu4+qIclHDX+X =mM8w -----END PGP SIGNATURE----- Merge tag 'rproc-v4.20' of git://github.com/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: "This contains a series of patches that reworks the memory carveout handling in remoteproc, in order to allow this to be reused for statically allocated memory regions to be used for e.g. firmware.

vfs: enable remap callers that can handle short operations
Plumb in a remap flag that enables the filesystem remap handler to shorten remapping requests for callers that can handle it. Now copy_file_range can report partial success (in case we run up against alignment problems, resource limits, etc.). We also enable CAN_SHORTEN for fideduperange to maintain existing userspace-visible behavior where xfs/btrfs shorten the dedupe range to avoid stale post-eof data exposure. Signed-off-by: Darrick J.

vfs: make remap_file_range functions take and return bytes completed
Change the remap_file_range functions to take a number of bytes to operate upon and return the number of bytes they operated on. This is a requirement for allowing fs implementations to return short clone/dedupe results to the user, which will enable us to obey resource limits in a graceful manner. A subsequent patch will enable copy_file_range to signal to the ->clone_file_range implementation that it can handle a short length, which will be returned in the function's return value. For now the short return is not implemented anywhere so the behavior won't change -- either copy_file_range manages to clone the entire range or it tries an alternative. Neither clone ioctl can take advantage of this, alas. Signed-off-by: Darrick J.
