The differences are: - x86_32's cpu_idle() makes use of check_pgt_cache(), which is a nop on both x86_32 and x86_64. - x86_64's cpu_idle() uses enter/__exit_idle/(), on x86_32 these function are a nop. - In contrast to x86_32, x86_64 calls rcu_idle_enter/exit() in the innermost loop because idle notifications need RCU. Calling these function on x86_32 also in the innermost loop does not hurt. So we can merge both functions.

Intel C1E is somehow involved 2. All AMD processors with C1E are involved Use the string "amd_c1e" instead of simply "c1e" to clarify that this workaround is specific to AMD's version of C1E. Use the string "e400" to clarify that the workaround is specific to AMD processors with Erratum 400. This patch is text-substitution only, with no functional change. cc: x86@kernel.org Acked-by: Borislav Petkov <borislav.petkov@amd.com> Signed-off-by: Len Brown <len.brown@intel.com> 2008-12-12T10:58:36+00:00 Hiroshi Shimamoto h-shimamoto@ct.jp.nec.com 2008-12-09T03:19:07+00:00 urn:sha1:8f2466f45f75e3cbe3aa2b69d33fd9d6e343b9cc Impact: cleanup Introduce helper inline function in arch/x86/include/asm/idle.h to remove #ifdefs around exit_idle().
