Description

In the Revision Gude for AMD Family 17h Models 00h-0Fh Processors, there are a handful of MSR-driven fixes to errata. Specifically:

1021 Load Operation May Receive Stale Data From Older Store Operation
Program MSR C001_1029 [13] to 1b.

1033 A Lock Operation May Cause the System to Hang
Program MSR C001_1020 [4] to 1b.

1049 FCMOV Instruction May Not Execute Correctly
Program MSR C001_1028 [4] to 1b.

1091 4K Address Boundary Crossing Load Operation May Receive Stale Data
Program MSR C001_102D [34] to 1b.

It would be nice to include the workarounds so any folks running illumos on the affected early-generation Zen CPUs can avoid those bugs.
