      ARM: at91: don't select CONFIG_ARM_CPU_SUSPEND for old platforms · dbeb0c8e
      Arnd Bergmann authored 
      My previous patch fixed a link error for all at91 platforms when
CONFIG_ARM_CPU_SUSPEND was not set, however this caused another
problem on a configuration that enabled CONFIG_ARCH_AT91 but none
of the individual SoCs, and that also enabled CPU_ARM720 as
the only CPU:

warning: (ARCH_AT91 && SOC_IMX23 && SOC_IMX28 && ARCH_PXA && MACH_MVEBU_V7 && SOC_IMX6 && ARCH_OMAP3 && ARCH_OMAP4 && SOC_OMAP5 && SOC_AM33XX && SOC_DRA7XX && ARCH_EXYNOS3 && ARCH_EXYNOS4 && EXYNOS5420_MCPM && EXYNOS_CPU_SUSPEND && ARCH_VEXPRESS_TC2_PM && ARM_BIG_LITTLE_CPUIDLE && ARM_HIGHBANK_CPUIDLE && QCOM_PM) selects ARM_CPU_SUSPEND which has unmet direct dependencies (ARCH_SUSPEND_POSSIBLE)
arch/arm/kernel/sleep.o: In function `cpu_resume':

arch/arm/kernel/suspend.o: In function `__cpu_suspend_save':
suspend.c:(.text+0x134): undefined reference to `cpu_arm720_do_suspend'

This improves the hack some more by only selecting ARM_CPU_SUSPEND
for the part that requires it, and changing pm.c to drop the
contents of unused init functions so we no longer refer to
cpu_resume on at91 platforms that don't need it.

      ext4: fix dir_nlink behaviour · c7414892
      Andreas Dilger authored 
      The dir_nlink feature has been enabled by default for new ext4
filesystems since e2fsprogs-1.41 in 2008, and was automatically
enabled by the kernel for older ext4 filesystems since the
dir_nlink feature was added with ext4 in kernel 2.6.28+ when
the subdirectory count exceeded EXT4_LINK_MAX-1.

Automatically adding the file system features such as dir_nlink is
generally frowned upon, since it could cause the file system to not be
mountable on older kernel, thus preventing the administrator from
rolling back to an older kernel if necessary.

In this case, the administrator might also want to disable the feature
because glibc's fts_read() function does not correctly optimize
directory traversal for directories that use st_nlinks field of 1 to
indicate that the number of links in the directory are not tracked by
the file system, and could fail to traverse the full directory
hierarchy.  Fortunately, in the past ten years very few users have
complained about incomplete file system traversal by glibc's
fts_read().

This commit also changes ext4_inc_count() to allow i_nlinks to reach
the full EXT4_LINK_MAX links on the parent directory (including "."
and "..") before changing i_links_count to be 1.

      ext4: silence array overflow warning · 381cebfe
      Dan Carpenter authored 
      I get a static checker warning:

    fs/ext4/ext4.h:3091 ext4_set_de_type()
    error: buffer overflow 'ext4_type_by_mode' 15 <= 15

It seems unlikely that we would hit this read overflow in real life, but
it's also simple enough to make the array 16 bytes instead of 15.

      ext4: fix SEEK_HOLE/SEEK_DATA for blocksize < pagesize · fcf5ea10
      Jan Kara authored 
      ext4_find_unwritten_pgoff() does not properly handle a situation when
starting index is in the middle of a page and blocksize < pagesize. The
following command shows the bug on filesystem with 1k blocksize:

  xfs_io -f -c "falloc 0 4k" \
            -c "pwrite 1k 1k" \
            -c "pwrite 3k 1k" \
            -c "seek -a -r 0" foo

In this example, neither lseek(fd, 1024, SEEK_HOLE) nor lseek(fd, 2048,
SEEK_DATA) will return the correct result.

Fix the problem by neglecting buffers in a page before starting offset.

      platform/x86: intel-vbtn: match power button on press rather than release · 946da699
      Mario Limonciello authored 
      This fixes a problem where the system gets stuck in a loop
unable to wakeup via power button in s2idle.

The problem happens because:
 - press power button:
   - system emits 0xc0 (power press), event ignored
   - system emits 0xc1 (power release), event processed,
     emited as KEY_POWER
   - set wakeup_mode to true
   - system goes to s2idle
 - press power button
   - system emits 0xc0 (power press), wakeup_mode is true,
     system wakes
   - system emits 0xc1 (power release), event processed,
     emited as KEY_POWER
   - system goes to s2idle again

To avoid this situation, process the presses (which matches what
intel-hid does too).

      Pull media fixes from Mauro Carvalho Chehab:
 "This series is larger than I would like to submit for -rc4. My
  original intent were to sent it to either -rc2 or -rc3. Unfortunately,
  due to my vacations, I got a lot of pending stuff after my return, and
  had to do some biz trips, with prevented me to send this earlier.

  Several fixes:

   - some fixes at atomisp staging driver

   - several gcc 7 warning fixes

   - cleanup media SVG files, in order to fix PDF build on some distros

   - fix random Kconfig build of venus driver

   - some fixes for the venus driver

   - some changes from semaphone to mutex in ngene's driver

   - some locking fixes at dib0700 driver

   - several fixes on ngene's driver and frontends to make it properly
     support some new boards added on Kernel 4.13

   - some fixes to CEC drivers

   - omap_vout: vrfb: convert to dmaengine

   - docs-rst: document EBUSY for VIDIOC_S_FMT

  Please notice that the big diffstat changes here are at the SVG files.

  Visually, the images look the same, but the file size is now a lot
  smaller than before, and they don't use some XML tags that would cause
  them to be badly parsed by some ImageMagick versions, or to require a
  lot of memory by TeTex, with would break PDF output on some
  distributions"

      ARM: dts: i.MX25: add ranges to tscadc · 83175620
      Martin Kaiser authored 
      Add a ranges; line to the tscadc node. This creates a 1:1 mapping between
the addresses used by tscadc and those in its child nodes (adc, tsc).

Without such a mapping, the reg = ... lines in the tsc and adc nodes do
not create a resource. Probing the fsl-imx25-tcq and fsl-imx25-tsadc
drivers will then fail since there's no IORESOURCE_MEM.

      soc: imx: gpcv2: fix regulator deferred probe · 9e01e2d5
      Stefan Agner authored 
      If a regulator requests a deferred probe, the power domain gets
initialized twice. This leads to a list double add (without
list debugging the kernel hangs due to the double add later):

  WARNING: CPU: 0 PID: 19 at lib/list_debug.c:31 __list_add_valid+0xbc/0xc4
  list_add double add: new=c1229754, prev=c12383b4, next=c1229754.

Initialize the power domain after we get the regulator. Also do
not print an error in case the regulator defers probing.
