Subjectlinux-next: manual merge of the powerpc tree with the powerpc-fixes tree
Hi all,

Today's linux-next merge of the powerpc tree got a conflict in:

arch/powerpc/include/asm/cputable.h
arch/powerpc/kernel/dt_cpu_ftrs.c

between commit:

a5d4b5891c2f ("powerpc/mm: Fixup tlbie vs store ordering issue on POWER9")

from the powerpc-fixes tree and commits:

9bbf0b576d32 ("powerpc: Free up CPU feature bits on 64-bit machines")
b5af4f279323 ("powerpc: Add CPU feature bits for TM bug workarounds on POWER9 v2.2")

from the powerpc 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.

Cheers,
Stephen Rothwell
