Subject: KVM: SVM: Fix workaround for AMD Errata 1096
Date: Mon, 15 Jul 2019 23:30:41 +0300	[thread overview]
Message-ID: <20190715203043.100483-1-liran.alon@oracle.com> (raw)

Hi,

This simple patch series aims to fix a bug in how KVM handles AMD Errata
1096.

1st patch is the fix. The bug was that vCPU state is checked incorrectly
for being able to possible raise a SMAP violation which is required to
encounter AMD Errata 1096.

2nd patch is a simple rename to make code more readable.

Disclaimer: I don't have the proper physical AMD machine to verify the
fix. I would appreciate if someone who have access to such AMD machine
will test it and reply.

Thanks,
-Liran
