      i2c: sunxi: add P2WI (Push/Pull 2 Wire Interface) controller support · 3e833490
      Boris BREZILLON 提交于
      The P2WI controller looks like an SMBus controller which only supports byte
      data transfers. But, it differs from standard SMBus protocol on several
      aspects:
      - it supports only one slave device, and thus drop the address field
      - it adds a parity bit every 8bits of data
      - only one read access is required to read a byte (instead of a write
        followed by a read access in standard SMBus protocol)
      - there's no Ack bit after each byte transfer
      
      This means this bus cannot be used to interface with standard SMBus
      devices (the only known device to support this interface is the AXP221
      PMIC).
      However the P2WI protocol is close enough to SMBus to be integrated in
      the I2C subsystem (see this thread [1] for detailed reasons that led to
      integrating this driver in the I2C subsystem).

      Pull pwm changes from Thierry Reding:
       "The majority of these changes are cleanups and fixes across all
        drivers.  Redundant error messages are removed and more PWM
        controllers set the .can_sleep flag to signal that they can't be used
        in atomic context.
      
        Support is added for the Broadcom Kona family of SoCs and the Intel
        LPSS driver can now probe PCI devices in addition to ACPI devices.
        Upon shutdown, the pwm-backlight driver will now power off the
        backlight.  It also uses the new descriptor-based GPIO API for more
        concise GPIO handling.
      
        A large chunk of these changes also converts platforms to use the
        lookup mechanism rather than relying on the global number space to
        reference PWM devices.  This is largely in preparation for more
        unification and cleanups in future patches.  Eventually it will allow
        the legacy PWM API to be removed"

      Pull powerpc updates from Ben Herrenschmidt:
       "Here is the bulk of the powerpc changes for this merge window.  It got
        a bit delayed in part because I wasn't paying attention, and in part
        because I discovered I had a core PCI change without a PCI maintainer
        ack in it.  Bjorn eventually agreed it was ok to merge it though we'll
        probably improve it later and I didn't want to rebase to add his ack.
      
        There is going to be a bit more next week, essentially fixes that I
        still want to sort through and test.
      
        The biggest item this time is the support to build the ppc64 LE kernel
        with our new v2 ABI.  We previously supported v2 userspace but the
        kernel itself was a tougher nut to crack.  This is now sorted mostly
        thanks to Anton and Rusty.
      
        We also have a fairly big series from Cedric that add support for
        64-bit LE zImage boot wrapper.  This was made harder by the fact that
        traditionally our zImage wrapper was always 32-bit, but our new LE
        toolchains don't really support 32-bit anymore (it's somewhat there
        but not really "supported") so we didn't want to rely on it.  This
        meant more churn that just endian fixes.
      
        This brings some more LE bits as well, such as the ability to run in
        LE mode without a hypervisor (ie. under OPAL firmware) by doing the
        right OPAL call to reinitialize the CPU to take HV interrupts in the
        right mode and the usual pile of endian fixes.
      
        There's another series from Gavin adding EEH improvements (one day we
        *will* have a release with less than 20 EEH patches, I promise!).
      
        Another highlight is the support for the "Split core" functionality on
        P8 by Michael.  This allows a P8 core to be split into "sub cores" of
        4 threads which allows the subcores to run different guests under KVM
        (the HW still doesn't support a partition per thread).
      
        And then the usual misc bits and fixes ..."

      hp-wmi: Enable hotkeys on some systems · f82bdd0d

      This is a third attempt to enable these buttons. The new variable being
      commit 997daa1b (i.e. hp-wmi: detect
      "2009 BIOS or later"). Older systems that do not have the 2009 BIOS query
      method respond with a dummy value, in this case 4. Using that, we can
      target a fairly narrow group of systems. i.e. old enough to not have
      HPWMI_FEATURE_QUERY 0xd, but new enough to have HPWMI_BIOS_QUERY 0x9.
      This group may be further limited if some systems respond with something
      other than 4 to non-existant feature queries.

      For the first 2 this nicely matches the icons on the keys, for the latter 2

      rtc: s5m: remove undocumented time init on first boot · fe787a5b
      Krzysztof Kozlowski 提交于
      Remove the code for initializing time if this is first boot.
      
      The code for detecting first boot uses undocumented field RTC_TCON in
      RTC_UDR_CON register.  According to S5M8767's datasheet this field is
      reserved.  On S2MPS14 it is not documented at all.
      
      On device first boot the registers will be initialized with reset value
      (2000-01-01 00:00:00).
      
      The code might work on S5M8763 but still this does not look like a task
      for RTC driver.

      mfd/rtc: sec/s5m: rename SEC* symbols to S5M · 602cb5bb
      Krzysztof Kozlowski 提交于
      Prepare for adding support for S2MPS14 RTC device to the rtc-s5m driver:
      
      1. Rename SEC* symbols to S5M.
      2. Add S5M prefix to some of defines which are different between S5M876X
         and S2MPS14.
      
      This is only a rename-like patch, new code is not added.

      gcov: add support for GCC 4.9 · a992bf83
      Yuan Pengfei 提交于
      This patch handles the gcov-related changes in GCC 4.9:
      
        A new counter (time profile) is added. The total number is 9 now.
      
        A new profile merge function __gcov_merge_time_profile is added.
      
      See gcc/gcov-io.h and libgcc/libgcov-merge.c
      
      For the first change, the layout of struct gcov_info is affected.
      
      For the second one, a dummy function is added to kernel/gcov/base.c
      similarly.

      decode_stacktrace: make stack dump output useful again · dbd1abb2
      Sasha Levin 提交于
      Right now when people try to report issues in the kernel they send stack
      dumps to eachother, which looks something like this:
      
        [    6.906437]  [<ffffffff811f0e90>] ? backtrace_test_irq_callback+0x20/0x20
        [    6.907121]  [<ffffffff84388ce8>] dump_stack+0x52/0x7f
        [    6.907640]  [<ffffffff811f0ec8>] backtrace_regression_test+0x38/0x110
        [    6.908281]  [<ffffffff813596a0>] ? proc_create_data+0xa0/0xd0
        [    6.908870]  [<ffffffff870a8040>] ? proc_modules_init+0x22/0x22
        [    6.909480]  [<ffffffff810020c2>] do_one_initcall+0xc2/0x1e0
        [...]
      
      However, most of the text you get is pure garbage.
      
      The only useful thing above is the function name.  Due to the amount of
      different kernel code versions and various configurations being used,
      the kernel address and the offset into the function are not really
      helpful in determining where the problem actually occured.
      
      Too often the result of someone looking at a stack dump is asking the
      person who sent it for a translation for one or more 'addr2line'
      translations.  Which slows down the entire process of debugging the
      issue (and really annoying).
      
      The decode_stacktrace script is an attempt to make the output more
      useful and easy to work with by translating all kernel addresses in the
      stack dump into line numbers.  Which means that the stack dump would
      look like this:
      
        [  635.148361]  dump_stack (lib/dump_stack.c:52)
        [  635.149127]  warn_slowpath_common (kernel/panic.c:418)
        [  635.150214]  warn_slowpath_null (kernel/panic.c:453)
        [  635.151031]  _oalloc_pages_slowpath+0x6a/0x7d0
        [  635.152171]  ? zone_watermark_ok (mm/page_alloc.c:1728)
        [  635.152988]  ? get_page_from_freelist (mm/page_alloc.c:1939)
        [  635.154766]  __alloc_pages_nodemask (mm/page_alloc.c:2766)
      
      It's pretty obvious why this is better than the previous stack dump
      before.
      
      Usage is pretty simple:
      
              ./decode_stacktrace.sh [vmlinux] [base path]
      
      Where vmlinux is the vmlinux to extract line numbers from and base path
      is the path that points to the root of the build tree, for example:
      
              ./decode_stacktrace.sh vmlinux /home/sasha/linux/ < input.log > output.log
      
      The stack trace should be piped through it (I, for example, just pipe
      the output of the serial console of my KVM test box through it).

         - stable fix for ensuring inode is declared uptodate only after all
           the attributes have been checked.
         - stable fix for a kernel Oops when remounting
         - NFS over RDMA client fixes
