[PATCH] i386: cleanups to help using per-cpu variables from asm

Browse source

This patch does a few small cleanups:
 - use PER_CPU_NAME to generate the names of per-cpu variables
 - use lea to add the per_cpu offset in PER_CPU(), because it doesn't
   affect condition flags
 - add PER_CPU_VAR which allows direct access to pre-cpu variables
   with the %fs: prefix on SMP.
