Hi all,
Today's linux-next merge of the kvm tree got a conflict in:
arch/x86/kernel/kvm.c
between commits:
b037b09b9058 ("x86/entry: Rename idtentry_enter/exit_cond_rcu() to idtentry_enter/exit()")
a27a0a55495c ("x86/entry: Cleanup idtentry_enter/exit")
from the tip tree and commits:
b1d405751cd5 ("KVM: x86: Switch KVM guest to using interrupts for page ready APF delivery")
26d05b368a5c ("Merge branch 'kvm-async-pf-int' into HEAD")
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.
