We'd like to eventually remove NO_IRQ on powerpc, so remove usages of it
from powerpc-only drivers.

The pdata structs are kzalloc'ed, so we don't need to initialise those
to 0, we can just drop the assignments entirely.

[ Boris: unbreak strings for easier greppability. ]
Signed-off-by: NBorislav Petkov <bp@suse.de>

On e500v1, read fault exception enable (RFXE) controls whether assertion
of core_fault_in causes a machine check interrupt. Assertion of
core_fault_in can result from uncorrectable data error, such as an L2
multi-bit ECC error. It can also occur from a system error if logic on
the integrated device signals a fault for nonfatal errors. RFXE bit is
cleared out of reset, and should be left clear for normal operation.
Assertion of core_fault_in does not cause a machine check.

RFXE is set specifically for RIO (Rapid IO) and PCI for book E to catch
the errors by machine check. With this bit set, the EDAC driver can't
get the interrupt in case of uncorrectable error. So this bit is cleared
in favor of EDAC. However, the benefit of catching such uncorrectable
error doesn't outweigh the other errors which may hang the system.
Besides, e500v2 has different errors masked by RFXE, and e500mc doesn't
support this bit. It is more reasonable to leave RFXE as is in the EDAC
driver, and leave the uncorrectable errors triggering machine check for
e500v1.

  round, all related to the bio op changes in this series.

  Two fixes, and then a cleanup, renaming bio->bi_rw to bio->bi_opf.  I
  wanted to do that change right after or right before -rc1, so that
  risk of conflict was reduced.  I just rebased the series on top of
  current master, and no new ->bi_rw usage has snuck in"

  block/mm: make bdev_ops->rw_page() take a bool for read/write

Pull drm zpos property support from Dave Airlie:
 "This tree was waiting on some media stuff I hadn't had time to get a
  stable branchpoint off, so I just waited until it was all in your tree
  first.

  It's been around a bit on the list and shouldn't affect anything
  outside adding the generic API and moving some ARM drivers to using
  it"

* tag 'drm-for-v4.8-zpos' of git://people.freedesktop.org/~airlied/linux:
  drm: rcar: use generic code for managing zpos plane property
  drm/exynos: use generic code for managing zpos plane property
  drm: sti: use generic zpos for plane
  drm: add generic zpos property

Since commit 63a4cc24, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.

No intended functional changes in this commit.

Commit abf54548 changed it from an 'rw' flags type to the
newer ops based interface, but now we're effectively leaking
some bdev internals to the rest of the kernel. Since we only
care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.

Then we can also move op_is_write() and friends back under
CONFIG_BLOCK protection.
