Hi all,
Today's linux-next merge of the xen-tip tree got a conflict in:
arch/x86/xen/enlighten.c
between commit:
9261e050b686 ("x86/asm/tsc, x86/paravirt: Remove read_tsc() and read_tscp() paravirt hooks")
from the tip tree and commit:
cd6f350a5460 ("xen/PMU: Initialization code for Xen PMU")
from the xen-tip tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
Thanks, this looks good.
