Hi all,
Today's linux-next merge of the kvm tree got a conflict in:
arch/arm64/include/asm/processor.h
between commit:
94b07c1f8c39 ("arm64: signal: Report signal frame size to userspace via auxv")
from the arm64 tree and commit:
9a6e594869b2 ("arm64/sve: Move sve_pffr() to fpsimd.h and make inline")
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.
