Hi all,
Today's linux-next merge of the kvm tree got a conflict in:
arch/x86/include/asm/sev-common.h
between commit:
34ff659017359 ("x86/sev: Use kernel provided SVSM Calling Areas")
from the tip tree and commit:
d46b7b6a5f9ec ("KVM: SEV: Add support to handle MSR based Page State Change VMGEXIT")
from the kvm tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
