The PA-RISC tool chain seems to have some problem with correct
read/write attributes on sections. This causes problems when the const
sections are fixed up for other architecture to only contain truly
read-only data.Disable const sections for PA-RISC
This can cause a bit of noise with modpost.

The ACARD driver calls udelay() with a value > 2000, which leads to to
the following compilation error on ARM:ERROR: "__bad_udelay" [drivers/scsi/atp870u.ko] undefined!
make[1]: *** [__modpost] Error 1This is because udelay is defined on ARM, roughly speaking, as
#define udelay(n) ((n) > 2000 ? __bad_udelay() : \
__const_udelay((n) * ((2199023U*HZ)>>11)))The argument to __const_udelay is the number of jiffies to wait divided
by 4, but this does not work unless the multiplication does not
overflow, and that is what the build error is designed to prevent. The
intended behavior can be achieved by using mdelay to call udelay
multiple times in a loop.[jrnieder@gmail.com: adding context]

The call if_changed mechanism does not work when the command contains
backslashes. This basically is an issue with lzo and bzip2 compressed
kernels. The compressed binaries do not contain the uncompressed image
size, so these use size_append to append the size. This results in
backslashes in the executed command. With this if_changed always
detects a change in the command and rebuilds the compressed image even
if nothing has changed.Fix this by escaping backslashes in make-cmd

Fengguang correctly points out that the firmware reading should not use
vfs_read(), since the buffer is in kernel space.The vfs_read() just happened to work for kernel threads, but sparse
warns about the incorrect address spaces, and it's definitely incorrect
and could fail for other users of the firmware loading.Reported-by: Fengguang Wu

Pull remoteproc update from Ohad Ben-Cohen:
- Remoteproc Recovery - by Fernando Guzman Lugo
When a remote processor crash is detected, this mechanism will remove
all virtio children devices, wait until their drivers let go, hard
reset the remote processor and reload the firmware (resulting in the
relevant virtio children devices re-added). Essentially the entire
software stack is reset, together with the relevant hardware, so
users don't have to reset the entire phone.- STE Modem driver is added - by Sjur Brændeland
- OMAP DSP boot address support is added - by Juan Gutierrez
- A handful of fixes/cleanups - Sjur Brændeland, Dan Carpenter, Emil
Goode* tag 'remoteproc-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc:

remoteproc: Add STE modem driver
remtoteproc: maintain max notifyid

Pull crypto update from Herbert Xu:

- 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... ]* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (71 commits)

Pull drm merge (part 1) from Dave Airlie:
"So first of all my tree and uapi stuff has a conflict mess, its my
fault as the nouveau stuff didn't hit -next as were trying to rebase
regressions out of it before we merged.Highlights:
- SH mobile modesetting driver and associated helpers
- some DRM core documentation
- i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
combined pte writing, ilk rc6 support,
- nouveau: major driver rework into a hw core driver, makes features
like SLI a lot saner to implement,
- psb: add eDP/DP support for Cedarview
- radeon: 2 layer page tables, async VM pte updates, better PLL
selection for > 2 screens, better ACPI interactionsThe rest is general grab bag of fixes.
So why part 1? well I have the exynos pull req which came in a bit
late but was waiting for me to do something they shouldn't have and it
looks fairly safe, and David Howells has some more header cleanups
he'd like me to pull, that seem like a good idea, but I'd like to get
this merge out of the way so -next dosen't get blocked."Tons of conflicts mostly due to silly include line changes, but mostly
mindless. A few other small semantic conflicts too, noted from Dave's
pre-merged branch.* 'drm-next' of git://people.freedesktop.org/~airlied/linux: (447 commits)

This is a first step in allowing people to by-pass udev for loading
device firmware. Current versions of udev will deadlock (causing us to
block for the 30 second timeout) under some circumstances if the
firmware is loaded as part of the module initialization path, and this
is causing problems for media drivers in particular.The current patch hardcodes the firmware path that udev uses by default,
and will fall back to the legacy udev mode if the firmware cannot be
found there. We'd like to add support for both configuring the paths
and the fallback behaviour, but in the meantime this hopefully fixes the
immediate problem, while also giving us a way forward.[ v2: Some VFS layer interface cleanups suggested by Al Viro ]
