98f541c6e3 USB: remove remaining instances of USB_SUSPEND
Commit 84ebc10294 (USB: remove
CONFIG_USB_SUSPEND option) failed to remove all of the usages of
USB_SUSPEND throughout the kernel.  This patch (as1677) removes the
remaining instances of that symbol.

Pull powerpc updates from Benjamin Herrenschmidt:
 "So from the depth of frozen Minnesota, here's the powerpc pull request
  for 3.9.  It has a few interesting highlights, in addition to the
  usual bunch of bug fixes, minor updates, embedded device tree updates
  and new boards:

   - Hand tuned asm implementation of SHA1 (by Paulus & Michael
     Ellerman)

   - Support for Doorbell interrupts on Power8 (kind of fast
     thread-thread IPIs) by Ian Munsie

   - Long overdue cleanup of the way we handle relocation of our open
     firmware trampoline (prom_init.c) on 64-bit by Anton Blanchard

   - Support for saving/restoring & context switching the PPR (Processor
     Priority Register) on server processors that support it.  This
     allows the kernel to preserve thread priorities established by
     userspace.  By Haren Myneni.

   - DAWR (new watchpoint facility) support on Power8 by Michael Neuling

   - Ability to change the DSCR (Data Stream Control Register) which
     controls cache prefetching on a running process via ptrace by
     Alexey Kardashevskiy

   - Support for context switching the TAR register on Power8 (new
     branch target register meant to be used by some new specific
     userspace perf event interrupt facility which is yet to be enabled)
     by Ian Munsie.

   - Improve preservation of the CFAR register (which captures the
     origin of a branch) on various exception conditions by Paulus.

   - Move the Bestcomm DMA driver from arch powerpc to drivers/dma where
     it belongs by Philippe De Muyter

   - Support for Transactional Memory on Power8 by Michael Neuling
     (based on original work by Matt Evans).  For those curious about
     the feature, the patch contains a pretty good description."

Note that in the latter, the larger SODIMM device appears 1st,
as mtd0 and mtd1, as indicated in the sizes, and in the date

The kernel configuration is the same in both cases; only the dtb
needs to be changed in accordance with the JP12/SW2.8 settings.

abf917cd91 cputime: Generic on-demand virtual cputime accounting
If we want to stop the tick further idle, we need to be
able to account the cputime without using the tick.

Virtual based cputime accounting solves that problem by
hooking into kernel/user boundaries.

However implementing CONFIG_VIRT_CPU_ACCOUNTING require
low level hooks and involves more overhead. But we already
have a generic context tracking subsystem that is required
for RCU needs by archs which plan to shut down the tick
outside idle.

This patch implements a generic virtual based cputime
accounting that relies on these generic kernel/user hooks.

There are some upsides of doing this:

- This requires no arch code to implement CONFIG_VIRT_CPU_ACCOUNTING
if context tracking is already built (already necessary for RCU in full
tickless mode).

- We can rely on the generic context tracking subsystem to dynamically
(de)activate the hooks, so that we can switch anytime between virtual
and tick based accounting. This way we don't have the overhead
of the virtual accounting when the tick is running periodically.

And one downside:

- There is probably more overhead than a native virtual based cputime
accounting. But this relies on hooks that are already set anyway.

 - IPsec ESN support in talitos and caam.
 - x86_64/avx implementation of cast5/cast6.
 - Add/use multi-algorithm registration helpers where possible.
 - Added IBM Power7+ in-Nest support.
 - Misc fixes.

Fix up trivial conflicts in crypto/Kconfig due to the sparc64 crypto
config options being added next to the new ARM ones.

[ Side note: cut-and-paste duplicate help texts make those conflicts
  harder to read than necessary, thanks to git being smart about
  minimizing conflicts and maximizing the common parts... ]

b92a66a65c powerpc: Add denormalisation exception handling for POWER6/7
On POWER6 and POWER7 if the input operand to an instruction is a
denormalised single precision binary floating point value we can take
a denormalisation exception where it's expected that the hypervisor
(HV=1) will fix up the inputs before the instruction is run.

This adds code to handle this denormalisation exception for POWER6 and
POWER7.

It also add a CONFIG_PPC_DENORMALISATION option and sets it in
pseries/ppc64_defconfig.

This is useful on bare metal systems only.  Based on patch from Milton
Miller.

Conflicts:
	net/netfilter/nfnetlink_log.c
	net/netfilter/xt_LOG.c

Rather easy conflict resolution, the 'net' tree had bug fixes to make
sure we checked if a socket is a time-wait one or not and elide the
logging code if so.

Whereas on the 'net-next' side we are calculating the UID and GID from
the creds using different interfaces due to the user namespace changes
from Eric Biederman.

34f84b5b5b powerpc/85xx: introduce support for the Freescale / iVeia P1022RDK
The Freescale / iVeia P1022RDK reference board is a small-factor board
with a Freescale P1022 SOC.  It includes:

1) 512 MB 64-bit DDR3-800 (max) memory
2) 8MB SPI serial flash memory for boot loader
3) Bootable 4-bit SD/MMC port
4) Two 10/100/1000 Ethernet connectors
5) One SATA port
6) Two USB ports
7) One PCIe x4 slot
8) DVI video connector
9) Audio input and output jacks, powered by a Wolfson WM8960 codec.

Unlike the P1022DS, the P1022RDK does not have any localbus devices,
presumably because of the localbus / DIU multiplexing restriction of
the P1022 SOC.

This updates the g5 defconfig to include nouveau instead of nvidiafb
(which works much better nowadays, in fact the latter crashes on modern

from the firmware offb by nouveau doesn't work properly (and leads to
unexplained black screens for some users).

b048b4e17c powerpc: remove Wind River SBC8560 support
This reference board dates back to 2004, and is largely a legacy
EOL product.  The MPC8560 is a pre e500v2 CPU.  The SBC8548 is
a more modern, better e500v2 target for people to use as a
reference board with today's kernels, should they require one.

Removing support for it will also allow us to remove some
sbc8560 specific quirk handling in 8250 UART code, and some
MTD mapping support.
