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 1
This 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.

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.

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.

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 interactions
The 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.

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.

[ v3: use the default udev paths suggested by Kay Sievers ]

Pull preparatory patches for user API disintegration from David Howells:
"The patches herein prepare for the extraction of the Userspace API
bits from the various header files named in the Kbuild files.
New subdirectories are created under either include/uapi/ or
arch/x/include/uapi/ that correspond to the subdirectory containing
that file under include/ or arch/x/include/.
The new subdirs under the uapi/ directory are populated with Kbuild
files that mostly do nothing at this time. Further patches will
disintegrate the headers in each original directory and fill in the
Kbuild files as they do it.
These patches also:
(1) fix up #inclusions of "foo.h" rather than <foo.h>.
(2) Remove some redundant #includes from the DRM code.
(3) Make the kernel build infrastructure handle Kbuild files both in
the old places and the new UAPI place that both specify headers
to be exported.
(4) Fix some kernel tools that #include kernel headers during their
build.
I have compile tested this with allyesconfig against x86_64,
allmodconfig against i386 and a scattering of additional defconfigs of
other arches. Prepared for main script

There's no caller of pcibios_assign_resources() in the tree. It is

Pull UBI changes from Artem Bityutskiy:
"The main change is the way we reserve eraseblocks for bad blocks
handling. We used to reserve 2% of the partition, but now we are more
aggressive and we reserve 2% of the entire chip, which is what
actually manufacturers specify in data sheets. We introduced an
option to users to override the default, though.
There are a couple of fixes as well, and a number of cleanups."

Pull vfs update from Al Viro:
- big one - consolidation of descriptor-related logics; almost all of
that is moved to fs/file.c
(BTW, I'm seriously tempted to rename the result to fd.c. As it is,
we have a situation when file_table.c is about handling of struct
file and file.c is about handling of descriptor tables; the reasons
are historical - file_table.c used to be about a static array of
struct file we used to have way back).
A lot of stray ends got cleaned up and converted to saner primitives,
disgusting mess in android/binder.c is still disgusting, but at least
doesn't poke so much in descriptor table guts anymore. A bunch of
relatively minor races got fixed in process, plus an ext4 struct file
leak.
- related thing - fget_light() partially unuglified; see fdget() in
there (and yes, it generates the code as good as we used to have).
- also related - bits of Cyrill's procfs stuff that got entangled into
that work; _not_ all of it, just the initial move to fs/proc/fd.c and
switch of fdinfo to seq_file.
- Alex's fs/coredump.c spiltoff - the same story, had been easier to
take that commit than mess with conflicts. The rest is a separate
pile, this was just a mechanical code movement.
- a few misc patches all over the place. Not all for this cycle,
there'll be more (and quite a few currently sit in akpm's tree)."
Fix up trivial conflicts in the android binder driver, and some fairly
simple conflicts due to two different changes to the sock_alloc_file()
interface ("take descriptor handling from sock_alloc_file() to callers"
vs "net: Providing protocol type via system.sockprotoname xattr of
/proc/PID/fd entries" adding a dentry name to the socket)

prom_printf() takes printf style arguments. Specifing GCC's format
attribute reveals that there are several wrong usages of prom_printf().
This fixes those wrong format strings and arguments, and also leaves
format attributes in order to detect similar mistakes at compile time.

Hopefully fixed the tlb flush timeout issue. Was able to observe this
condition occur occasionally, and it appears the binary driver doesn't
wait on the old condition either..
Should give 39-bit DMA addressing on the relevant chipsets.

Something seems to be missing in regards to flushing specific ranges of
the TLB. For the moment, flushing the entire thing seems to make it
work alright.
Should give 39-bit DMA addressing on the relevant chipsets.

For now, only 2 control modes are available:
- NONE: The fan is never touched (default)
- MANUAL: The fan is set to the user-defined fan speed (pwm1)
This patch introduces a distinction between ptherm internal fan management
and external fan management. The latter is bound to respect the fan mode
while the first can still select the speed it wants unless the NONE mode
is selected. This is important for automatic fan management.

The previous driver waited for 250ms to accumulate data. This version times a
complete fan rotation and extrapolates to RPM.
The fan rotational speed should now be read in less than 250ms (worst case)
and usually in less 50ms.

It looks scary because of the size, but I tried to keep the differences minimal.
Further patches will fix the actual "driver" code and add new features.
v2: change filenames, split to submodules
v3: add a missing include
v4: Ben Skeggs <bskeggs@redhat.com>
- fixed set_defaults() to allow min_duty < 30 (thermal table will
override this if it's actually necessary)
- fixed set_defaults() to not provide pwm_freq so nv4x (which only has
pwm_div) can actually work. the boards using pwm_freq will have a
thermal table entry to provide us the value.
- removed unused files
