      [ARM] 4373/1: i.MX/MX1 GPIO support implementation · b3e6a508
      Pavel Pisa 提交于
      Support for generic input output for MX1 family.
      The implementation prevents allocation of one pin
      by two users, but does not store pointer to the user
      description permanently, because this solution
      would have bigger memory overhead.
      
      The simple way to integrate code with per BSP
      pins setup and allocation is required else all GPIO
      registration checking is useless. The function
      imx_gpio_setup_multiple_pins() can be used for this
      purpose in future.

      [ARM] Fix non-page aligned boot time mappings · 7b9c7b4d
      Russell King 提交于
      AT91SAM9260 stopped booting with the recent changes to MM
      initialisation - it was asking for a non-aligned virtual address
      which caused loops to be non-terminal.  Fix this by rounding
      virtual addresses down, but remember to include the offset in
      the length, and round the length up to the following page.
      
      This means that asking for a mapping of 4K starting at 2K into
      a page maps two pages as one would expect.

      Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARM · edd5cd4a
      David Woodhouse 提交于
      Not all the world is an i386.  Many architectures need 64-bit arguments to be
      aligned in suitable pairs of registers, and the original
      sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an
      argument register for padding after the first integer.  Since we don't
      normally have more than 6 arguments for system calls, that left no room for
      the final argument on some architectures.
      
      Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which
      all fits nicely.  In fact, ARM already had that, but called it
      sys_arm_sync_file_range.  Move it to fs/sync.c and rename it, then implement
      the needed compatibility routine.  And stop the missing syscall check from
      bitching about the absence of sys_sync_file_range() if we've implemented
      sys_sync_file_range2() instead.
      
      Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

      Fix a real section mismatch issue; the test code is thrown away after

      Detach sched.h from mm.h · e8edc6e0
      Alexey Dobriyan 提交于
      First thing mm.h does is including sched.h solely for can_do_mlock() inline
      function which has "current" dereference inside. By dealing with can_do_mlock()
      mm.h can be detached from sched.h which is good. See below, why.
      
      This patch
      a) removes unconditional inclusion of sched.h from mm.h
      b) makes can_do_mlock() normal function in mm/mlock.c
      c) exports can_do_mlock() to not break compilation
      d) adds sched.h inclusions back to files that were getting it indirectly.
      e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
         getting them indirectly
      
      Net result is:
      a) mm.h users would get less code to open, read, preprocess, parse, ... if
         they don't need sched.h
      b) sched.h stops being dependency for significant number of files:
         on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
         after patch it's only 3744 (-8.3%).
      
      Cross-compile tested on
