Use the mcsafe_key defined in the previous patch to make decisions on which copy function to use. We can't use the FEATURE bit any more because PCI quirks run too late to affect the patching of code. So we use a static key. Turn memcpy_mcsafe() into an inline function to make life easier for callers. The assembly code that actually does the copy is now named memcpy_mcsafe_unrolled() Signed-off-by: Tony Luck <tony.luck@intel.com> Acked-by: Borislav Petkov <bp@suse.de> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Dan Williams <dan.j.williams@intel.com> Cc: Boris Petkov <bp@suse.de> Cc: Linus Torvalds <torvalds@linux-foundation.org> Link: http://lkml.kernel.org/r/bfde2fc774e94f53d91b70a4321c85a0d33e7118.1472754712.git.tony.luck@intel.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de> |
