      arm: delete __cpuinit/__CPUINIT usage from all ARM users · 8bd26e3a
      Paul Gortmaker 提交于
      The __cpuinit type of throwaway sections might have made sense
      some time ago when RAM was more constrained, but now the savings
      do not offset the cost and complications.  For example, the fix in
      commit 5e427ec2 ("x86: Fix bit corruption at CPU resume time")
      is a good example of the nasty type of bugs that can be created
      with improper use of the various __init prefixes.
      
      After a discussion on LKML[1] it was decided that cpuinit should go
      the way of devinit and be phased out.  Once all the users are gone,
      we can then finally remove the macros themselves from linux/init.h.
      
      Note that some harmless section mismatch warnings may result, since
      notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
      and are flagged as __cpuinit  -- so if we remove the __cpuinit from
      the arch specific callers, we will also get section mismatch warnings.
      As an intermediate step, we intend to turn the linux/init.h cpuinit
      related content into no-ops as early as possible, since that will get
      rid of these warnings.  In any case, they are temporary and harmless.
      
      This removes all the ARM uses of the __cpuinit macros from C code,
      and all __CPUINIT from assembly code.  It also had two ".previous"
      section statements that were paired off against __CPUINIT
      (aka .section ".cpuinit.text") that also get removed here.

      ARM: mm: fix boot on SA1110 Assabet · 319e0b4f
      Russell King 提交于
      Commit 83db0384 (mm/ARM: use common help functions to free reserved
      pages) broke booting on the Assabet by trying to convert a PFN to
      a virtual address using the __va() macro.  This macro takes the
      physical address, not a PFN.  Fix this.

      ARM: 7781/1: mmu: Add debug_ll_io_init() mappings to early mappings · ee4de5d9
      Stephen Boyd 提交于
      Failure to add the mapping created in debug_ll_io_init() can lead
      to the BUG_ON() triggering in lib/ioremap.c:27 if the static
      virtual address decided for the debug_ll mapping overlaps with
      another mapping that is created later. This happens because the
      generic ioremap code has no idea there is a mapping there and it
      tries to place a mapping in the same location and blows up when
      it sees that there is a pte already present.

      Fix it by telling generic layers about the static mapping via
      iotable_init().  This also has the nice side effect of letting
      you see the mapping in procfs' vmallocinfo file.

      ARM: 7780/1: add missing linker section markup to head-common.S · 8c69d7af
      Stephen Warren 提交于
      Macro __INIT is used to place various code in head-common.S into the init
      section. This should be matched by a closing __FINIT. Also, add an
      explicit ".text" to ensure subsequent code is placed into the correct
      section; __FINIT is simply a closing marker to match __INIT and doesn't
      guarantee to revert to .text.
      
      This historically caused no problem, because macro __CPUINIT was used at
      the exact location where __FINIT was missing, which then placed following
      code into the cpuinit section. However, with commit 22f0a273 "init.h:
      remove __cpuinit sections from the kernel" applied, __CPUINIT becomes a
      no-op, thus leaving all this code in the init section, rather than the
      regular text section. This caused issues such as secondary CPU boot
      failures or crashes.
