Merge branch 'next/cleanup' into samsung/dt

Conflicts:
arch/arm/mach-exynos/common.c

The common.c file gets changes from rmk/stable-devel (part of
next/cleanup), rmk/restart, samsung/dt and follow-on branches
from the samsung tree.

Pulling it all together here hopefully avoids having to do
even more conflicting merge changesets in this one file. What
a mess!

ARM: 7267/1: Remove BUILD_BUG_ON from asm/bug.h

BUILD_BUG_ON is defined in linux/kernel.h but that is not included by the
asm/bug.h header which uses it. This causes a build error:

...include/linux/mtd/map.h: In function 'inline_map_read':
...include/linux/mtd/map.h:408:3: error: implicit declaration of function
'BUILD_BUG_ON' [-Werror=implicit-function-declaration]

just remove it.

ARM: restart: remove the now empty arch_reset()

Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite.  Remove arm_machine_restart() as this function
no longer does anything useful.

For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions.  As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.

ARM: 7236/1: vic: always use simple ops

Now that irq_domain_simple_ops are available for non-DT users, use them
in the VIC driver so that we don't get a NULL dereference in
irq_domain_to_irq() when registering the domain.

ARM: 7242/1: PL330: Detach the request from the pl330_thread when it finishes successful

When a request has finished successfully and we are about to call its
callback, remove its pointer from the corresponding pl330_thread .
This prevents the core driver from calling its callback again if
pl330_release_channel() is called without first flushing the device.
When pl330_update() returns, the driver is allowed to free the pointer
to pl330_req so the core driver shouldn't be able to access it again.

futex: Fix uninterruptible loop due to gate_area

It was found (by Sasha) that if you use a futex located in the gate
area we get stuck in an uninterruptible infinite loop, much like the
ZERO_PAGE issue.

While looking at this problem, PeterZ realized you'll get into similar
trouble when hitting any install_special_pages() mapping.  And are there
still drivers setting up their own special mmaps without page->mapping,
and without special VM or pte flags to make get_user_pages fail?

In most cases, if page->mapping is NULL, we do not need to retry at all:
Linus points out that even /proc/sys/vm/drop_caches poses no problem,
because it ends up using remove_mapping(), which takes care not to
interfere when the page reference count is raised.

But there is still one case which does need a retry: if memory pressure
called shmem_writepage in between get_user_pages_fast dropping page
table lock and our acquiring page lock, then the page gets switched from
filecache to swapcache (and ->mapping set to NULL) whatever the refcount.
Fault it back in to get the page->mapping needed for key->shared.inode.

procfs: do not confuse jiffies with cputime64_t

Commit 2a95ea6c0d129b4 ("procfs: do not overflow get_{idle,iowait}_time
for nohz") did not take into account that one some architectures jiffies
and cputime use different units.

This causes get_idle_time() to return numbers in the wrong units, making
the idle time fields in /proc/stat wrong.

Instead of converting the usec value returned by
get_cpu_{idle,iowait}_time_us to units of jiffies, use the new function
usecs_to_cputime64 to convert it to the correct unit of cputime64_t.
