      ARM: at91: fix pm declarations · a91c5824
      Arnd Bergmann authored
      In a recent rearrangement of the at91 pm initialization code, a broken
      set of declarations was added for the !CONFIG_PM-case, leading to
      this link error:
      
      arch/arm/mach-at91/board-dt-sama5.o: In function `at91_rm9200_pm_init':
      arch/arm/mach-at91/generic.h:40: multiple definition of `at91_rm9200_pm_init'
      arch/arm/mach-at91/setup.o:arch/arm/mach-at91/generic.h:40: first defined here
      arch/arm/mach-at91/board-dt-sama5.o: In function `at91_sam9260_pm_init':
      arch/arm/mach-at91/generic.h:41: multiple definition of `at91_sam9260_pm_init'
      arch/arm/mach-at91/setup.o:arch/arm/mach-at91/generic.h:41: first defined here
      arch/arm/mach-at91/board-dt-sama5.o: In function `at91_sam9g45_pm_init':

      arch/arm/mach-at91/setup.o:arch/arm/mach-at91/generic.h:42: first defined here
      
      This adds the missing 'static inline' to the declarations to avoid
      creating a copy of the functions in each file that includes the
      header.

      ARM: davinci: multi-soc kernels require AUTO_ZRELADDR · 99bd667a
      Arnd Bergmann authored
      The davinci DA8xx and DMx families have incompatible zreladdr
      settings, and attempting to build a kernel with both enabled
      results in an error unless AUTO_ZRELADDR is set:
      
      multiple zreladdrs: 0xc0008000 0x80008000
      This needs CONFIG_AUTO_ZRELADDR to be set
      
      This patch changes Kconfig to make the two families mutually
      exclusive when this is unset.

      ARM: davinci: davinci_cfg_reg cannot be init · 31612d64
      Arnd Bergmann authored
      davinci_cfg_reg gets called from a lot of locations that
      might get called after the init section has been discarded,
      so the function itself must not be marked __init either.
      
      The kernel build currently warns about this with lots of
      messages like:
      
      WARNING: vmlinux.o(.text.unlikely+0x24c): Section mismatch in reference from the function dm365evm_mmc_configure() to the function .init.text:davinci_cfg_reg()
      The function dm365evm_mmc_configure() references
      the function __init davinci_cfg_reg().
      This is often because dm365evm_mmc_configure lacks a __init
      annotation or the annotation of davinci_cfg_reg is wrong.
      
      This removes the extraneous __init_or_module annotation.

      ARM: BCM: put back ARCH_MULTI_V7 dependency for mobile · ff34cae5
      Arnd Bergmann authored
      A recent cleanup rearranged the Kconfig file for mach-bcm and
      accidentally dropped the dependency on ARCH_MULTI_V7, which
      makes it possible to now build the two mobile SoC platforms
      on an ARMv6-only kernel, resulting in a log of Kconfig
      warnings like
      
      warning: ARCH_BCM_MOBILE selects ARM_ERRATA_775420 which has unmet direct dependencies (CPU_V7)
      
      and which of course cannot work on any machine.
      
      This puts back the dependencies as before.

      ARM: vexpress: use ARM_CPU_SUSPEND if needed · 95fcedb0
      Arnd Bergmann authored
      The vexpress tc2 power management code calls mcpm_loopback, which
      is only available if ARM_CPU_SUSPEND is enabled, otherwise we
      get a link error:

      Pull ARM SoC platform changes from Olof Johansson:
       "New and updated SoC support.  Also included are some cleanups where
        the platform maintainers hadn't separated cleanups from new developent
        in separate branches.
      
        Some of the larger things worth pointing out:
      
         - A large set of changes from Alexandre Belloni and Nicolas Ferre
           preparing at91 platforms for multiplatform and cleaning up quite a
           bit in the process.
      
         - Removal of CSR's "Marco" SoC platform that never made it out to the
           market.  We love seeing these since it means the vendor published
           support before product was out, which is exactly what we want!
      
        New platforms this release are:
      
         - Conexant Digicolor (CX92755 SoC)
         - Hisilicon HiP01 SoC
         - CSR/sirf Atlas7 SoC
         - ST STiH418 SoC
         - Common code changes for Nvidia Tegra132 (64-bit SoC)
      
        We're seeing more and more platforms having a harder time labelling
        changes as cleanups vs new development -- which is a good sign that
        we've come quite far on the cleanup effort.  So over time we might
        start combining the cleanup and new-development branches more"

      rtc: add driver for DS1685 family of real time clocks · aaaf5fbf
      Joshua Kinard authored
      This adds a driver for the Dallas/Maxim DS1685-family of RTC chips.  It
      supports the DS1685/DS1687, DS1688/DS1691, DS1689/DS1693, DS17285/DS17287,
      DS17485/DS17487, and DS17885/DS17887 RTC chips.  These chips are commonly
      found in SGI O2 and SGI Octane systems.  It was originally derived from a
      driver patch submitted by Matthias Fuchs many years ago for use in
      EPPC-405-UC modules, which also used these RTCs.  In addition to the
      time-keeping functions, this RTC also handles the shutdown mechanism of
      the O2 and Octane and acts as a partial NVRAM for the boot PROMS in these
      systems.
      
      Verified on both an SGI O2 and an SGI Octane.

      Here we do not call ocfs2_prepare_orphan_dir and ocfs2_orphan_add

      result in more than one orphan entry for the same inode.

      ocfs2: prepare some interfaces used in append direct io · 026749a8
      Joseph Qi authored
      Currently in case of append O_DIRECT write (block not allocated yet),
      ocfs2 will fall back to buffered I/O.  This has some disadvantages.
      Firstly, it is not the behavior as expected.  Secondly, it will consume
      huge page cache, e.g.  in mass backup scenario.  Thirdly, modern
      filesystems such as ext4 support this feature.
      
      In this patch set, the direct I/O write doesn't fallback to buffer I/O
      write any more because the allocate blocks are enabled in direct I/O now.
      
      This patch (of 9):
      
      Prepare some interfaces which will be used in append O_DIRECT write.

      ext2: get rid of most mentions of XIP in ext2 · 9c3ce9ec
      Matthew Wilcox authored
      To help people transition, accept the 'xip' mount option (and report it in
      /proc/mounts), but print a message encouraging people to switch over to
      the 'dax' option.

      vfs,ext2: remove CONFIG_EXT2_FS_XIP and rename CONFIG_FS_XIP to CONFIG_FS_DAX · 6cd176a5
      Matthew Wilcox authored
      The fewer Kconfig options we have the better.  Use the generic
      CONFIG_FS_DAX to enable XIP support in ext2 as well as in the core.

      ext2: remove ext2_xip_verify_sb() · 0de4830f
      Matthew Wilcox authored
      Jan Kara pointed out that calling ext2_xip_verify_sb() in ext2_remount()
      doesn't make sense, since changing the XIP option on remount isn't
      allowed.  It also doesn't make sense to re-check whether blocksize is
      supported since it can't change between mounts.
      
      Replace the call to ext2_xip_verify_sb() in ext2_fill_super() with the
      equivalent check and delete the definition.

       Also remove mm/filemap_xip.c as it is now empty.  Also remove

      Based on the original XIP documentation, this documents the current state
