x86, amd: Disable GartTlbWlkErr when BIOS forgets it
commit 5bbc097d890409d8eff4e3f1d26f11a9d6b7c07e upstream.
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.
