linux-next: manual merge of the s390 tree with Linus' tree

linux-next: manual merge of the s390 tree with Linus' tree

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the s390 tree got a conflict in:

  arch/s390/include/asm/mmu_context.h

between commit:

  0b89ede62963 ("s390/mm: fork vs. 5 level page tabel")

from Linus' tree and commit:

  f1c1174fa099 ("s390/mm: use new mm defines instead of magic values")

from the s390 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.

Fixup looks fine, thank you!

Hi all,

Today's linux-next merge of the s390 tree got a conflict in:

  arch/s390/kernel/smp.c

between commit:

  8ebf6da9db1b ("s390/ftrace: fix potential crashes when switching tracers")

from Linus' tree and commit:

  11886c199d8d ("s390: add machine check SIGP")

from the s390 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.

Hi all,

Today's linux-next merge of the s390 tree got a conflict in
arch/s390/pci/pci_debug.c between commit c2f0b61d8969 ("s390: remove
use of seq_printf return value") from Linus' tree and commit
80ed156a3d12 ("s390/pci: add locking for fmb access") from the s390
tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

That works, thanks. The other fixup you are carrying should be gone now,
I had to pull in 2.6.39 final to resolve other conflicts.

linux-next: manual merge of the s390 tree with Linus' tree

Hi all,

Today's linux-next merge of the s390 tree got a conflict in
drivers/s390/char/tape_block.c between commit 9fd097b14918 ("block:
unexport DISK_EVENT_MEDIA_CHANGE for legacy/fringe drivers") from Linus'
tree and commit 263fa17de50e ("[S390] Remove tape block device driver")
from the s390 tree.

The latter just removes the file updated by the former.  So I did that.
