      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.

      locking/mcs: Allow architecture specific asm files to be used for contended case · ddf1d169
      Tim Chen 提交于
      This patch allows each architecture to add its specific assembly optimized
      arch_mcs_spin_lock_contended and arch_mcs_spinlock_uncontended for
      MCS lock and unlock functions.
