This fixes a regression for the Nomadik on the main system
timers.
The Nomadik seemed a bit slow and its heartbeat wasn't looking
healthy. And it was not strange, because it has been connected
to the 32768 Hz clock at boot, while being told by the clock driver
that it was 2.4MHz. Actually connect the TIMCLK to 2.4MHz by
default as this is what we want for nice scheduling, clocksource
and clock event.

This patch is a dependency for Sebastian Hesselbarth's series that
cleans up the ARM machine descriptor's .init_time hook. It may also end
up being a dependency for cleanup/development in the Tegra tree, and
hence is contained in its own topic branch, to allow conflicts to be
easily resolved.

Patch 638591c enabled building the AES assembler code in Thumb2 mode.
However, this code used arithmetic involving PC rather than adr{l}
instructions to generate PC-relative references to the lookup tables,
and this needs to take into account the different PC offset when
running in Thumb mode.

A series of wrong 'struct dev' assumptions in suspend/resume callbacks

One to watch out for in future.
A number of driver specific fixes
1) at91 - fix a overflow in clock rate computation
2) dummy - Kconfig dependency issue
3) isl29018 - uninitialized value
4) hmc5843 - measurement conversion bug introduced by recent cleanup.
5) ade7854-spi - wrong return value.
Some IIO core fixes
1) Wrong value picked up for event code creation for a modified channel
2) A null dereference on failure to initialize a buffer after no buffer has
been in use, when using the available_scan_masks approach.
3) Sampling not stopped when a device is removed. Effects forced removal
such as hot unplugging.
4) Prevent device going away if a chrdev is still open in userspace.
5) Prevent race on chardev opening and device being freed.
6) Add a missing iio_buffer_init in the call back buffer.

Adding the number of bios in a remapped request to 'block_rq_remap'

Request remapper clones bios in a request to track the completion

Commit 377747c406 ("ARM: entry: allow ARM-private syscalls to be
restarted") reworked the low-level syscall dispatcher to allow
restarting of ARM-private syscalls. Unfortunately, this relocated the
label used to dispatch a private syscall from the trace path, so that
the invocation would be bypassed altogether!
This causes applications to fail under strace as soon as they rely on
a private syscall (e.g. set_tls):
set_tls(0xb6fad4c0, 0xb6fadb98, 0xb6fb1050, 0xb6fad4c0, 0xb6fb1050)
= -1 ENOSYS (Function not implemented)
This patch fixes the label so that we correctly dispatch private
syscalls from the trace path.
