      ARM: dts: exynos: add needs-hpd for Odroid-XU3/4 · 93a4c835
      Hans Verkuil authored
      CEC support was added for Exynos5 in 4.13, but for the Odroids we need to set
      'needs-hpd' as well since CEC is disabled when there is no HDMI hotplug signal,
      just as for the exynos4 Odroid-U3.
      
      This is due to the level-shifter that is disabled when there is no HPD, thus
      blocking the CEC signal as well. Same close-but-no-cigar board design as the
      Odroid-U3.
      
      Tested with my Odroid XU4.

      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).

        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.
