[SRU][FOCAL][PATCH 0/1] kvm: svm: Update svm_xsaves_supported

[William Breathitt Gray]

SRU Justification
=================

[Impact]

AMD CPUs now support XSAVES in a limited fashion (they require IA32_XSS
to be zero).

AMD has no equivalent of Intel's "Enable XSAVES/XRSTORS" VM-execution
control. Instead, XSAVES is always available to the guest when supported
on the host.

[Regression Potential]

Very low chance of regression; previous code returned false for all CPUs
while change should only return true when the CPU reports support for
the XSAVES feature.

[Miscellaneous]

Commit 52297436199d is the last remaining patch necessary to add support
for the EPYC-v3 and EPYC-Rome CPU model to Focal.
