      kprobes: move kprobe declarations to asm-generic/kprobes.h · 7d134b2c
      Luis R. Rodriguez 提交于
      Often all is needed is these small helpers, instead of compiler.h or a
      full kprobes.h.  This is important for asm helpers, in fact even some
      asm/kprobes.h make use of these helpers...  instead just keep a generic
      asm file with helpers useful for asm code with the least amount of
      clutter as possible.
      
      Likewise we need now to also address what to do about this file for both
      when architectures have CONFIG_HAVE_KPROBES, and when they do not.  Then
      for when architectures have CONFIG_HAVE_KPROBES but have disabled
      CONFIG_KPROBES.
      
      Right now most asm/kprobes.h do not have guards against CONFIG_KPROBES,
      this means most architecture code cannot include asm/kprobes.h safely.
      Correct this and add guards for architectures missing them.
      Additionally provide architectures that not have kprobes support with
      the default asm-generic solution.  This lets us force asm/kprobes.h on
      the header include/linux/kprobes.h always, but most importantly we can
      now safely include just asm/kprobes.h on architecture code without
      bringing the full kitchen sink of header files.
      
      Two architectures already provided a guard against CONFIG_KPROBES on its
      kprobes.h: sh, arch.  The rest of the architectures needed gaurds added.
      We avoid including any not-needed headers on asm/kprobes.h unless
      kprobes have been enabled.
      
      In a subsequent atomic change we can try now to remove compiler.h from
      include/linux/kprobes.h.
      
      During this sweep I've also identified a few architectures defining a
      common macro needed for both kprobes and ftrace, that of the definition
      of the breakput instruction up.  Some refer to this as
      BREAKPOINT_INSTRUCTION.  This must be kept outside of the #ifdef
      CONFIG_KPROBES guard.

      sched/cputime: Remove generic asm headers · b672592f
      Frederic Weisbecker 提交于
      cputime_t is now only used by two architectures:
      
      	* powerpc (when CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y)
      	* s390
      
      And since the core doesn't use it anymore, we don't need any arch support
      from the others. So we can remove their stub implementations.
      
      A final cleanup would be to provide an efficient pure arch
      implementation of cputime_to_nsec() for s390 and powerpc and finally
      remove include/linux/cputime.h .

      Make asm/word-at-a-time.h available on all architectures · a6e2f029
      Chris Metcalf 提交于
      Added the x86 implementation of word-at-a-time to the
      generic version, which previously only supported big-endian.
      
      Omitted the x86-specific load_unaligned_zeropad(), which in
      any case is also not present for the existing BE-only
      implementation of a word-at-a-time, and is only used under
      CONFIG_DCACHE_WORD_ACCESS.
      
      Added as a "generic-y" to the Kbuilds of all architectures
      that didn't previously have it.
