ARM: SoC 64-bit changes for v4.9
Changes to platform code for 64-bit ARM platforms. We are not adding any new platforms that require code or Kconfig changes this time, so it's basically just defconfig changes to enable support for more drivers used on the existing platforms. This is mainly interesting for the Raspberry Pi 3, which should now work much better with the default build. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAWFLxS2CrR//JCVInAQJJDQ/9EVxolfQKMjld6M/ZpOaw1O/+rKUdFyUC S6PIJgQD9/DIUVU+PMtHjljp+2GK0lJpLNXK3Tb4sJjx68ry9PSSHjZMEOJv33nE mNsq3oQmbpPfZ6ufJrNqj1tS1ScxGDqudIx2L+DHwpg+lJjs984tKDQ4Ta18VI7m k+a2IxoBWzGvzE50NFJppryZBq4p1WspfAkBLfohtTRGlCtmztbai6YZT0zfL1Iy qdynNlh9yT5Y+JTTbnwPWJPH+YqsAMBeu/OqWyVfvpRc+fzPNIBNHrb5MfoWV6sP JGyRUoQ0tDb0r+BTk68/5ALtKQQ40sxvPPpJgqRBy72gN5F4WhfIhfhP5zBMoyLU X0pmPVB9CBFCz0BqUXcGofM/LvLLZeWOk+iAtl33AwmZ9U/e/e1Nobu9rqjv3hf1 nPqsDtisCo6RzDBfLCXX7XwX0GfRp3K81jWXIM7aULzhkrnFiPfz69qGFERLoTQf w35n0YpT6yZDRsYYdTxprXD9y64fg4fKsp5XEQB6cE5Ea43AuH0WruxtazOGbJrz nkatIO7dyK1/kl7fZZIxQiVY4F874j5X2bJPiCpB+vgDnkmPy8YV0PCfyRUA6jmK sFsQFGTbqquXiKdtjwz+wrL0yRESgmCswaPBTiwD5cQC7s3GnCOkFsMvetuRLGk2 WSdHwEQ886k= =B+Lz -----END PGP SIGNATURE----- Merge tag 'armsoc-arm64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC 64-bit updates from Arnd Bergmann: "Changes to platform code for 64-bit ARM platforms.

ARM: SoC defconfig updates for v4.10
Defconfig additions, removals, etc. Most of these are small changes adding the options for newly upstreamed drivers, or drivers needed for new board support. Bartlomiej Zolnierkiewicz has done a series of patches reducing the use of CONFIG_IDE from 19 to 3 in favor of CONFIG_ATA. Overall more patches than usual, but nothing big. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAWFLwc2CrR//JCVInAQJeBRAApGEjTZoI/J5N6IqUIYM65bfvh/BVgfDf H7L8YPgP0BGy6zbj+XMyL4gsA+WRk6eWNGwMlwuOtsNkGx//hp9iFEd1ElHed/Um 09jE7WufcKd9L9ZEexVxPV/8yjxUqWhiH99FSxbPvuoczXmzcpk4LGeSD22OYOZ7 wODG0xAce9gvgByjHCo0AvfRJs3XZxJ0S9DigXWXHBD3Q7w8z+FOh+kbJROIUr7L Ik+ZpoWj8ZQ2jQsIo2NWtSRfZotT6Z3CJnqQNzkEG3jmiqXCorNtQ5QLBVdmqrKp 8ykZaok5cCwVchFBD8SzOnempGSplPBqjrBzSwq+IhAN0yMFLZtBZeUciLjxEIjf aWWsGOOMSe9JiNWVQp6urCOfx4HHnq1SODlKWTJh5fbFLJl91KdqYnmfeaxg+06w 19p6L0XVND4hErsMPaUozIITtcpNXquDzHPquSxYOc6cALM3qUlAoG8xGkPGwNP5 UrnWgcPy56FEFejC3exO2vGHDiqMhwRviQXAqBDPUjQUXRDbTHFyRMCG6iTqMG64 o7CVoAfzny3FUiWAdG1I6zisEDAVF1W7ctNkd3oY6cTiGpS7g3Yu+hq0FVMp7Xk8 qx6KqK0HrH5O59l6/BsD0TgyoVH96Nql0/KoxiJr6oMCbVrBNn0BJA8I5BXAd+Zd gqXnf9e1Xf8= =2XsL -----END PGP SIGNATURE----- Merge tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC defconfig updates from Arnd Bergmann: "Defconfig additions, removals, etc. Most of these are small changes adding the options for newly upstreamed drivers, or drivers needed for new board support.

ARM: SoC platform updates for v4.10
These are updates for platform specific code on 32-bit ARM machines, essentially anything that can not (yet) be expressed using DT files. Noteworthy changes include: - Added support for the TI DRA71x family of SoCs in mach-omap2, this is an new variant of the the DRA72x/DRA74x automotive infotainment chips we already supported for a while. - Added support for the ST STM32F746 SoC, the first Cortex-M7 based microcontroller we support, related to the smaller STM32F4 family. - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile, see http://elinux.org/RZ-G - SMP is now supported on the OX820 platform - A lot of code in mach-omap2 gets removed as a follow-up to removing support for board files in the previous release - Davinci has some new work to improve USB support - For i.MX, the performance monitor now supports profiling the memory controller using 'perf' Conflicts: arch/arm/mach-shmobile/setup-rcar-gen2.c: rcar_gen2_clocks_init() is gone, calling of_clk_init(NULL) is sufficient now. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAWFMS9WCrR//JCVInAQIG+Q/7BElvubqO/Cc/VEAyoB5iF9OB9wPD2t5p O0KwtrTtzqJZJNGTmPiesR4DMZH07O1XoW8HqvBPeXtB7/t0tmOegwK+WABbpkSE ZQgUjtrIGwteJXYqU2BbhooO8G6mEsfWaqdGX8ZiIk40fPhMN6536lG+JA8DV7uv ckAPHCZkIf34lDtwljN97Cvj1TT9lBFp04bx7alKqfg1IMV+iMSxvSRHuuFlxRCk kzwVXDmFlZLmueU2KbQXTuOUrvehIGlZ/X5QWlxfrjwCwnOvr54p8WDoVWu2UkHm Dc8BVfsBny8mCZJRzfDD1S0PD0mWn1msdOhRb4VRzsC9DnRI4qbL0/Hstu8A7yUQ kBtMyVtFTzvRSclABbHHN6Mnm37AyNwSIKIB8h2U1m7YHqZGwHLaflVT5sf3tl7m 4arTVqHtR8oSU5G5a2FTznMM2rfIx4LcCBbLQxWqzmO4Qrh4j6t7c2i7+VTfFAja 0bToLgTArKK/cep6PWeBnMH14nzlXoKtBf2T8qwQPuAmLKy9E0ZduLKZ01B/nqrj OXcsnG0OUuqU4RgbIaDssRU4ohKIk8JcAl60TdRFhzj+/LTbeMaWVwbWuQS+iHd3 zfzGUoUIhElx0vHt6ghR0BYQadszb1z9V0NEs3UM0v5cWlNodX//3okH8lZmSW6w +fO4dSnIKIA= =BF6Y -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "These are updates for platform specific code on 32-bit ARM machines, essentially anything that can not (yet) be expressed using DT files.

ARM: SoC non-urgent fixes for v4.10
As usual, we queue up a few fixes that don't seem urgent enough to go in through -rc, or that just came a little too late given their size. The zx fixes make the platform finally boot on real hardware, the davinci and imx31 get the DT support working better for some of the machines that are still normally used with classic board files. One tegra fix is important for new bootloader versions, but the bug has been around for a while without anyone noticing. The other changes are mostly cosmetic. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAWFLum2CrR//JCVInAQJTJhAAmLTsJE0O9akmxytLzlMsy+xhIHvXBfkx mCDr0sVwHFVm2vcH0bPlK4sNrjGYjIV0Qfsh4Br9NzohCxe6s8xFvPA78aYk5AZp kiHRv8Gap3dYTV2p6P2loeQ3o0zN7kl9/gUPOy6v4La84kUyZi9RRpyhA+HlEuwW loQQ6LaSVQb8dMo8Lz5GdOk4YfWyy1DSoZ1uNwD/2bqgfIDQ5MPdjwQzHeK259xE 8WfVKtS4RXl54Psj26BfHRrH8VE8cMxfZ3eZwGykiXpOusrjNVbIEPJK8nKHuGHJ Ui/nAMzvCD23bsVX2JCYAKa/zRWjXqpvrHEzLJsaWq1VqtmWFS7g9wi1DjZmBBoC eJZI8Sg/7qL8Rkc69XSzyRUdMxdS6JfWQ6HrM/qzouja6MoRdFdbzl1WiPyYaVGd gBa7Lx6hQJgSWkeu0mvERdDAzjf4weeZyMFOFov0CwzMZ4VTKCR6Rk4lc8I1A/Hz 0QcCmUj7uXC+gA6U+ZBlvDkG+e1u0Me5i+0gCCphd3UaReB5WaEriNubEwEMitci QI9BGIMzG974UXU9CCIwcnpFvJKSRwuZsQmPpulP1vbfIb8ajZXQ779PW5szE6qI h9VMtnKlDbOUEzdj6l/sCs2mWrobCr8/44cWOz7R8b31ZhBZxyJRWhIE/YvZFEvF Dq5OzaCNLxM= =i2l2 -----END PGP SIGNATURE----- Merge tag 'armsoc-fixes-nc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC non-urgent fixes from Arnd Bergmann: "As usual, we queue up a few fixes that don't seem urgent enough to go in through -rc, or that just came a little too late given their size.

This release has a few updates:
o STM can hook into the function tracer o Function filtering now supports more advance glob matching o Ftrace selftests updates and added tests o Softirq tag in traces now show only softirqs o ARM nop added to non traced locations at compile time o New trace_marker_raw file that allows for binary input o Optimizations to the ring buffer o Removal of kmap in trace_marker o Wakeup and irqsoff tracers now adhere to the set_graph_notrace file o Other various fixes and clean ups Note, there are two patches marked for stable. These were discovered near the end of the 4.9 rc release cycle. By the time I had them tested it was just a matter of days before 4.9 would be released, and I figured I would just submit them in the merge window. They are old bugs and not critical. Nothing non-root could abuse. -----BEGIN PGP SIGNATURE----- iQExBAABCAAbBQJYUrFHFBxyb3N0ZWR0QGdvb2RtaXMub3JnAAoJEMm5BfJq2Y3L 2+AIAIr20kSQV/nA5htGAeCTobVk3WUxY6bvjd9mIJDKPP19akNLyREW0G3KnfCr yhx4aFRZG98fRu/6F8qieRosyN36lADDVYHelMFHMpcTOpE2aZGjaaOuNGxOEA9v FmMPTX+K3+dzKyFP4l68R3+5JuQ1/AqLTioTWeLW8IDQ2OOVsjD8+0BuXrNKMJDY o6U4Hk5U/vn+zHc6BmgBzloAXemBd7iJ1t5V3FRRGvm8yv3HU85Twc5ofGeYTWvB J8PboEywRlIzxg0Kd8mxnMI5PgaKZSEc2ub8E7cY/CZ5PYpDE2xDA2hJmJgfYp00 1VW+DHRpRZfElsCcya6S6P4bs5Y= =MGZ/ -----END PGP SIGNATURE----- Merge tag 'trace-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "This release has a few updates: - STM can hook into the function tracer - Function filtering now supports more advance glob matching - Ftrace selftests updates and added tests - Softirq tag in traces now show only softirqs - ARM nop added to non traced locations at compile time - New trace_marker_raw file that allows for binary input - Optimizations to the ring buffer - Removal of kmap in trace_marker - Wakeup and irqsoff tracers now adhere to the set_graph_notrace file - Other various fixes and clean ups" * tag 'trace-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (42 commits) selftests: ftrace: Shift down default message verbosity kprobes/trace: Fix kprobe selftest for newer gcc tracing/kprobes: Add a helper method to return number of probe hits tracing/rb: Init the CPU mask on allocation tracing: Use SOFTIRQ_OFFSET for softirq dectection for more accurate results tracing/fgraph: Have wakeup and irqsoff tracers ignore graph functions too fgraph: Handle a case where a tracer ignores set_graph_notrace tracing: Replace kmap with copy_from_user() in trace_marker writing ftrace/x86_32: Set ftrace_stub to weak to prevent gcc from using short jumps to it tracing: Allow benchmark to be enabled at early_initcall() tracing: Have system enable return error if one of the events fail tracing: Do not start benchmark on boot up tracing: Have the reg function allow to fail ring-buffer: Force rb_end_commit() and rb_set_commit_to_write() inline ring-buffer: Froce rb_update_write_stamp() to be inlined ring-buffer: Force inline of hotpath helper functions tracing: Make __buffer_unlock_commit() always_inline tracing: Make tracepoint_printk a static_key ring-buffer: Always inline rb_event_data() ring-buffer: Make rb_reserve_next_event() always inlined ... |

Merge branch 'i2c/for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: - the first series of making i2c_device_id optional instead of mandatory (in favor of alternatives like of_device_id). This involves adding a new probe callback (probe_new) which removes some peculiarities I2C had for a long time now. The new probe is matching the other subsystems now and the old one will be removed once all users are converted. It is expected to take a while but there is ongoing interest in that. - SMBus Host Notify introduced 4.9 got refactored. They are now using interrupts instead of the alert callback which solves multiple issues. - new drivers for iMX LowPower I2C, Mellanox CPLD and its I2C mux - significant refactoring for bcm2835 driver - the usual set of driver updates and improvements * 'i2c/for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (46 commits) i2c: fsl-lpi2c: read lpi2c fifo size in probe() i2c: octeon: thunderx: Remove double-check after interrupt i2c: octeon: thunderx: TWSI software reset in recovery i2c: cadence: Allow Cadence I2C to be selected for Cadence Xtensa CPUs i2c: sh_mobile: Add per-Generation fallback bindings i2c: rcar: Add per-Generation fallback bindings i2c: imx-lpi2c: add low power i2c bus driver dt-bindings: i2c: imx-lpi2c: add devicetree bindings i2c: designware-pcidrv: Add 10bit address feature to medfield/merrifield i2c: pxa: Add support for the I2C units found in Armada 3700 i2c: pxa: Add definition of fast and high speed modes via the regs layout dt-bindings: i2c: pxa: Update the documentation for the Armada 3700 i2c: qup: support SMBus block read i2c: qup: add ACPI support i2c: designware: Consolidate default functionality bits i2c: i2c-mux-gpio: update mux with gpiod_set_array_value_cansleep i2c: mux: pca954x: Add ACPI support for pca954x i2c: use an IRQ to report Host Notify events, not alert i2c: i801: remove SMBNTFDDAT reads as they always seem to return 0 i2c: i801: use the BIT() macro for FEATURES_* also ... |

"PCI changes:
- add support for PCI on ARM64 boxes with ACPI. We already had this
for theoretical spec-compliant hardware; now we're adding quirks
for the actual hardware (Cavium, HiSilicon, Qualcomm, X-Gene)
- add runtime PM support for hotplug ports
- enable runtime suspend for Intel UHCI that uses platform-specific
wakeup signaling
- add yet another host bridge registration interface. We hope this is
extensible enough to subsume the others
- expose device revision in sysfs for DRM
- to avoid device conflicts, make sure any VF BAR updates are done
before enabling the VF
- avoid unnecessary link retrains for ASPM
- allow INTx masking on Mellanox devices that support it

"This is the complete update for the rdma stack for this release cycle.
Most of it is typical driver and core updates, but there is the
entirely new VMWare pvrdma driver. You may have noticed that there
were changes in DaveM's pull request to the bnxt Ethernet driver to
support a RoCE RDMA driver. The bnxt_re driver was tentatively set to
be pulled in this release cycle, but it simply wasn't ready in time
and was dropped (a few review comments still to address, and some
multi-arch build issues like prefetch() not working across all
arches).

printk: remove console flushing special cases for partial buffered lines
It actively hurts proper merging, and makes for a lot of special cases.
There was a good(ish) reason for doing it originally, but it's getting
too painful to maintain. And most of the original reasons for it are
long gone.
So instead of having special code to flush partial lines to the console
(as opposed to the record buffers), do _all_ the console writing from
the record buffer, and be done with it.
If an oops happens (or some other synchronous event), we will flush the
partial lines due to the oops printing activity, so this does not affect
that. It does mean that if you have a completely hung machine, a
partial preceding line may not have been printed out.
That was some of the original reason for this complexity, in fact, back
when we used to test for the historical i386 "halt" instruction problem
by doing
pr_info("Checking 'hlt' instruction... ");
if (!boot_cpu_data.hlt_works_ok) {
pr_cont("disabled\n");
return;
}
halt();
halt();
halt();
halt();
pr_cont("OK\n");
and that model no longer works (it the 'hlt' instruction kills the
machine, the partial line won't have been flushed, so you won't even see
it).
Of course, that was also back in the days when people actually had
textual console output rather than a graphical splash-screen at bootup.
How times change..

printk: remove games with previous record flags
The record logging code looks at the previous record flags in various ways, and they are all wrong. You can't use the previous record flags to determine anything about the next record, because they may simply not be related. In particular, the reason the previous record was a continuation record may well be exactly _because_ the new record was printed by a different process, which is why the previous record was flushed. So all those games are simply wrong, and make the code hard to understand (because the code fundamentally cdoes not make sense). So remove it.

Various small fixes for IPMI. Cleanups in the documentation and
convertion printk() to pr_xxx() and removal of an unused module parameter. Some small bug fixes and enhancements. This also adds a post softdep from the IPMI core module to the IPMI device interface. Many people have complained that the device interface isn't automatically avaiable when IPMI is loaded. I don't want to make the device interface mandatory, though, plenty of people use IPMI internally (like with ACPI) and don't need a device interface or the added possible security entry. A softdep should make it work "out of the box" but allow people to not have it if they don't want it. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEABECAAYFAlhSE9cACgkQIXnXXONXERe6iACgsiU5/LG4tbKu9EyZXp5isRw6 AdsAn1dT08aobOzJhFI3dVx6oTnJQDDC =ifi5 -----END PGP SIGNATURE----- Merge tag 'for-linus-4.10' of git://git.code.sf.net/p/openipmi/linux-ipmi Pull IPMI updates from Corey Minyard: "Various small fixes for IPMI.

radix-tree: ensure counts are initialised
radix_tree_join() was freeing nodes with a non-zero ->exceptional count, and radix_tree_split() wasn't zeroing ->exceptional when it allocated the new node. Fix this by making all callers of radix_tree_node_alloc() pass in the new counts (and some other always-initialised fields), which will prevent the problem recurring if in future we decide to do something similar.

radix tree test suite: cache recently freed objects
The kmem_cache_alloc implementation simply allocates new memory from malloc() and calls the ctor, which zeroes out the entire object. This means it cannot spot bugs where the object isn't properly reinitialised before being freed. Add a small (11 objects) cache before freeing objects back to malloc. This is enough to let us write a test to catch it, although the memory allocator is now aware of the structure of the radix tree node, since it chains free objects through ->private_data (like the percpu cache does).

radix-tree: add radix_tree_split
This new function splits a larger multiorder entry into smaller entries (potentially multi-order entries). These entries are initialised to RADIX_TREE_RETRY to ensure that RCU walkers who see this state aren't confused. The caller should then call radix_tree_for_each_slot() and radix_tree_replace_slot() in order to turn these retry entries into the intended new entries. Tags are replicated from the original multiorder entry into each new entry.

radix-tree: add radix_tree_join
This new function allows for the replacement of many smaller entries in the radix tree with one larger multiorder entry. From the point of view of an RCU walker, they may see a mixture of the smaller entries and the large entry during the same walk, but they will never see NULL for an index which was populated before the join.

radix-tree: delete radix_tree_range_tag_if_tagged()
This is an exceptionally complicated function with just one caller (tag_pages_for_writeback). We devote a large portion of the runtime of the test suite to testing this one function which has one caller. By introducing the new function radix_tree_iter_tag_set(), we can eliminate all of the complexity while keeping the performance. The caller can now use a fairly standard radix_tree_for_each() loop, and it doesn't need to worry about tricksy things like 'start' wrapping. The test suite continues to spend a large amount of time investigating this function, but now it's testing the underlying primitives such as radix_tree_iter_resume() and the radix_tree_for_each_tagged() iterator which are also used by other parts of the kernel.

radix-tree: improve multiorder iterators
This fixes several interlinked problems with the iterators in the presence of multiorder entries. 1. radix_tree_iter_next() would only advance by one slot, which would result in the iterators returning the same entry more than once if there were sibling entries. 2. radix_tree_next_slot() could return an internal pointer instead of a user pointer if a tagged multiorder entry was immediately followed by an entry of lower order. 3. radix_tree_next_slot() expanded to a lot more code than it used to when multiorder support was compiled in. And I wasn't comfortable with entry_to_node() being in a header file. Fixing radix_tree_iter_next() for the presence of sibling entries necessarily involves examining the contents of the radix tree, so we now need to pass 'slot' to radix_tree_iter_next(), and we need to change the calling convention so it is called *before* dropping the lock which protects the tree. Also rename it to radix_tree_iter_resume(), as some people thought it was necessary to call radix_tree_iter_next() each time around the loop. radix_tree_next_slot() becomes closer to how it looked before multiorder support was introduced. It only checks to see if the next entry in the chunk is a sibling entry or a pointer to a node; this should be rare enough that handling this case out of line is not a performance impact (and such impact is amortised by the fact that the entry we just processed was a multiorder entry). Also, radix_tree_next_slot() used to force a new chunk lookup for untagged entries, which is more expensive than the out of line sibling entry skipping.
