-Subject: x86/pti: Make sure the user/kernel PTEs match
-
-Meelis reported that his K8 Athlon64 emits MCE warnings when PTI is
-enabled:
-
-[Hardware Error]: Error Addr: 0x0000ffff81e000e0
-[Hardware Error]: MC1 Error: L1 TLB multimatch.
-[Hardware Error]: cache level: L1, tx: INSN
-
-The address is in the entry area, which is mapped into kernel _AND_ user
-space. That's special because we switch CR3 while we are executing
-there.
-
-User mapping:
-0xffffffff81e00000-0xffffffff82000000           2M     ro         PSE     GLB x  pmd
-
-Kernel mapping:
-0xffffffff81000000-0xffffffff82000000          16M     ro         PSE         x  pmd
-
-So the K8 is complaining that the TLB entries differ. They differ in the
-GLB bit.
-
-Drop the GLB bit when installing the user shared mapping.
-

-Ok. Found the real issue. This is a problem on AMD boxen.

-Fix below.

-Can Xen folks please have a look at that as well?
