We currently return -EPERM if the user requests mode exclusion that is
not supported by the CPU. This looks pretty confusing from userspace
and is inconsistent with other architectures (ppc, x86).
This patch returns -EOPNOTSUPP instead.

This reverts commit 6b5c8045ecc7e726cdaa2a9d9c8e5008050e1252.
Conflicts:
arch/arm/kernel/ptrace.c
The new syscall restarting code can lead to problems if we take an
interrupt in userspace just before restarting the svc instruction. If
a signal is delivered when returning from the interrupt, the
TIF_SYSCALL_RESTARTSYS will remain set and cause any syscalls executed
from the signal handler to be treated as a restart of the previously
interrupted system call. This includes the final sigreturn call, meaning
that we may fail to exit from the signal context. Furthermore, if a
system call made from the signal handler requires a restart via the
restart_block, it is possible to clear the thread flag and fail to
restart the originally interrupted system call.
The right solution to this problem is to perform the restarting in the
kernel, avoiding the possibility of handling a further signal before the
restart is complete. Since we're almost at -rc6, let's revert the new
method for now and aim for in-kernel restarting at a later date.

The OMAP4 usb_host_fs (OHCI) and AESS IP blocks require some special
programming for them to enter idle. Without this programming, they
will prevent the rest of the chip from entering full chip idle.
To implement the idle programming cleanly, this will take some
coordination between maintainers. This is likely to take some time,
so it is probably best to leave this for 3.6 or 3.7. So, in the
meantime, prevent these IP blocks from being registered.
Later, once the appropriate support is available, this patch can be
reverted.
This second version comments out the IP block data since Benoît didn't
like removing it.

We have a bug report where the kernel hits a warning in the cpumask

Which is:
WARN_ON_ONCE(cpu >= nr_cpumask_bits);
The backtrace is:
cpu_cmd
cmds
xmon_core
xmon
die
xmon is iterating through 0 to NR_CPUS. I'm not sure why we are still
open coding this but iterating above nr_cpu_ids is definitely a bug.
This patch iterates through all possible cpus, in case we issue a
system reset and CPUs in an offline state call in.
Perhaps the old code was trying to handle CPUs that were in the
partition but were never started (eg kexec into a kernel with an
nr_cpus= boot option). They are going to die way before we get into
xmon since we haven't set any kernel state up for them.

Pull two ARM fixes from Russell King:
"It's been fairly quiet with the fixes. Just two this time. One fixes
a long standing problem with KALLSYMS needing an additional pass, and
the other sorts a problem with the vmalloc space interacting with
static IO mappings."
* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
ARM: 7438/1: fill possible PMD empty section gaps
ARM: 7428/1: Prevent KALLSYM size mismatch on ARM.
On ARM with the 2-level page table format, a PMD entry is represented by
two consecutive section entries covering 2MB of virtual space.
However, static mappings always were allowed to use separate 1MB section
entries. This means in practice that a static mapping may create half
populated PMDs via create_mapping().
Since commit 0536bdf33f (ARM: move iotable mappings within the vmalloc
region) those static mappings are located in the vmalloc area. We must
ensure no such half populated PMDs are accessible once vmalloc() or
ioremap() start looking at the vmalloc area for nearby free virtual
address ranges, or various things leading to a kernel crash will happen.

Basic suspend/resume is fixed by ensuring that the PGSR registers are
set correctly before sleep mode is entered. In particular four of the
active low resets need to be driven high while in sleep mode, otherwise
the unit resets itself instead of suspending. Another problem was that
the PCFR_GPROD bit is set by the HTC bootloader; this caused GPIO reset
(i.e. the reset button) to fail immediately after returning from sleep
mode.

Commit f948501b36c6 ("Make hard_irq_disable() actually hard-disable
interrupts") caused check_and_cede_processor to stop working.
->irq_happened will never be zero right after a hard_irq_disable
so the compiler removes the call to cede_processor completely.
The bug was introduced back in the lazy interrupt handling rework
of 3.4 but was hidden until recently because hard_irq_disable did
nothing.
This issue will eventually appear in 3.4 stable since the
hard_irq_disable fix is marked stable, so mark this one for stable

As I was adding code that affects all archs, I started testing function
tracer against PPC64 and found that it currently locks up with 3.4
kernel. I figured it was due to tracing a function that shouldn't be, so
I went through the following process to bisect to find the culprit:
cat /debug/tracing/available_filter_functions > t
num=`wc -l t`
sed -ne "1,${num}p" t > t1
let num=num+1
sed -ne "${num},$p" t > t2
cat t1 > /debug/tracing/set_ftrace_filter
echo function /debug/tracing/current_tracer
<failed? bisect t1, if not bisect t2>
It finally came down to this function: restore_interrupts()
I'm not sure why this locks up the system. It just seems to prevent
scheduling from occurring. Interrupts seem to still work, as I can ping
the box. But all user processes freeze.
When restore_interrupts() is not traced, function tracing works fine.

In entry_64.S version of ret_from_except_lite, you'll notice that
in the !preempt case, after we've checked MSR_PR we test for any
TIF flag in _TIF_USER_WORK_MASK to decide whether to go to do_work
or not. However, in the preempt case, we do a convoluted trick to
test SIGPENDING only if PR was set and always test NEED_RESCHED ...
but we forget to test any other bit of _TIF_USER_WORK_MASK !!! So
that means that with preempt, we completely fail to test for things
like single step, syscall tracing, etc...
This should be fixed as the following path:
- Test PR. If not set, go to resume_kernel, else continue.
- If go resume_kernel, to do that original do_work.
- If else, then always test for _TIF_USER_WORK_MASK to decide to do
that original user_work, else restore directly.

If the kernel is big enough (eg. allyesconfig), the linker may need to
switch TOCs when calling from the BPF JIT code out to the external
helpers (skb_copy_bits() & bpf_internal_load_pointer_neg_helper()).
In order to do that we need to leave space after the bl for the linker
to insert a reload of our TOC pointer.

The problem is that currently none of the clocks are being registered for
OMAP4470 devices and so on boot-up no clocks can be found and the kernel panics.
This fix allows the kernel to boot without failure using a simple RAMDISK file
system on OMAP4470 blaze board.
Per feedback from Paul and Benoit the 4470 clock data is incomplete for new
modules such as the 2D graphics block that has been added to the 4470.
Therefore add a warning to indicate that the clock data is incomplete.

Commit 20ef9e08 ("ARM: EXYNOS: Support DMA for EXYNOS5250 SoC")
renamed EXYNOS4_DEV_DMA to EXYNOS_DEV_DMA. But some machine entries
still had EXYNOS4_DEV_DMA. Changed them to EXYNOS_DEV_DMA.

There was a stray %s left from testing, remove it.
Add -w to the #! line (which is parsed by Perl even if the Perl
interpreter is invoked explicitly on the command line) to catch these
kinds of errors in the future.

commit 8259573b (ARM: OMAP2+: nand: Make board_onenand_init() visible
to board code) broke the build for configs with OneNAND disabled. By
removing the static in the header file, it created a duplicate definition
in the .c and the .h files, resuling in a build error:
/work/kernel/omap/dev/arch/arm/mach-omap2/board-flash.c:102:111: error: redefinition of 'board_onenand_init'
/work/kernel/omap/dev/arch/arm/mach-omap2/board-flash.h:56:51: note: previous definition of 'board_onenand_init' was here
make[2]: *** [arch/arm/mach-omap2/board-flash.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [arch/arm/mach-omap2] Error 2
make: *** [sub-make] Error 2
Fix this by removing the duplicate dummy entry from the C file.
