      drivers: delete __cpuinit usage from all remaining drivers files · a83048eb
      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.
      
      This removes all the remaining one-off uses of the __cpuinit macros
      from all C files in the drivers/* directory.

      that don't really have a specific maintainer.

      are flagged as __cpuinit  -- so if we remove the __cpuinit from
      arch specific callers, we will also get section mismatch warnings.
      As an intermediate step, we intend to turn the linux/init.h cpuinit
      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 arch/x86 uses of the __cpuinit macros from
      all C files.  x86 only had the one __CPUINIT used in assembly files,
      and it wasn't paired off with a .previous or a __FINIT, so we can
      delete it directly w/o any corresponding additional change there.

      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)
      are flagged as __cpuinit  -- so if we remove the __cpuinit from
      arch specific callers, we will also get section mismatch warnings.
      As an intermediate step, we intend to turn the linux/init.h cpuinit
      content into no-ops as early as possible, since that will get rid
      of these warnings.  In any case, they are temporary and harmless.

      Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
      with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
      disable migration. But the SLUB code is relatively lockless, and the
      spin_locks there are raw_spin_locks (not converted to mutexes), thus I
      believe this bug can happen in mainline without -rt features. The -rt
      patch is just good at triggering mainline bugs ;-)
      
      Anyway, looking at where this crashed, it seems that the page variable
      can be NULL when passed to the node_match() function (which does not
      check if it is NULL). When this happens we get the above panic.
      
      As page is only used in slab_alloc() to check if the node matches, if
      it's NULL I'm assuming that we can say it doesn't and call the
      __slab_alloc() code. Is this a correct assumption?

       "O_TMPFILE ABI changes, Oleg's fput() series, misc cleanups, including
        making simple_lookup() usable for filesystems with non-NULL s_d_op,
        which allows us to get rid of quite a bit of ugliness"
