linux-next: manual merge of the kvm-ppc-paulus tree with the powerpc tree

[Stephen Rothwell]

Hi Paul,

Today's linux-next merge of the kvm-ppc-paulus tree got a conflict in:

  arch/powerpc/mm/pgtable-radix.c

between commit:

  555c16328ae6 ("powerpc/mm: Correct process and partition table max size")

from the powerpc tree and commit:

  9d66195807ac ("powerpc/64: Provide functions for accessing POWER9 partition table")

from the kvm-ppc-paulus tree.

I fixed it up (the latter removed the code modified by the former) 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.

Hi Paul,

Today's linux-next merge of the kvm-ppc-paulus tree got a conflict in:

  arch/powerpc/include/asm/reg.h

between commit:

  29a969b76481 ("powerpc: Revert Load Monitor Register Support")

from the powerpc tree and commits:

  7fd317f8c330 ("powerpc/64: Add some more SPRs and SPR bits for POWER9")
  02ed21aeda0e ("powerpc/powernv: Define and set POWER9 HFSCR doorbell bit")

from the kvm-ppc-paulus 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

Hi Paul,

Today's linux-next merge of the kvm-ppc-paulus tree got a conflict in:

  arch/powerpc/kernel/traps.c

between commit:

  42f5b4cacd78 ("powerpc: Introduce asm-prototypes.h")

from the powerpc tree and commit:

  fd7bacbca47a ("KVM: PPC: Book3S HV: Fix TB corruption in guest exit path on HMI interrupt")

from the kvm-ppc-paulus 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.
