      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.

      locking/mcs: Order the header files in Kbuild of each architecture in alphabetical order · b119fa61
      Tim Chen 提交于
      We perform a clean up of the Kbuid files in each architecture.
      We order the files in each Kbuild in alphabetical order
      by running the below script.
      
      for i in arch/*/include/asm/Kbuild
      do
              cat $i | gawk '/^generic-y/ {
                      i = 3;
                      do {
                              for (; i <= NF; i++) {
                                      if ($i == "\\") {
                                              getline;
                                              i = 1;

                                      if ($i != "")
                                              hdr[$i] = $i;
                              }

      arm64: fix alignment padding in assembly code · aeed41a9
      Marc Zyngier 提交于
      An interesting effect of using the generic version of linkage.h
      is that the padding is defined in terms of x86 NOPs, which can have
      even more interesting effects when the assembly code looks like this:
      
      ENTRY(func1)
      	mov	x0, xzr
      ENDPROC(func1)
      	// fall through
      ENTRY(func2)
      	mov	x0, #1
      	ret
      ENDPROC(func2)
      
      Admittedly, the code is not very nice. But having code from another
      architecture doesn't look completely sane either.
      
      The fix is to add arm64's version of linkage.h, which causes the insertion
      of proper AArch64 NOPs.
