x86, amd: Disable GartTlbWlkErr when BIOS forgets it
This patch disables GartTlbWlk errors on AMD Fam10h CPUs if
the BIOS forgets to do is (or is just too old). Letting
these errors enabled can cause a sync-flood on the CPU
causing a reboot.
The AMD BKDG recommends disabling GART TLB Wlk Error completely.
This patch is the fix for
https://bugzilla.kernel.org/show_bug.cgi?id=33012
on my machine.
