Switch to the generic extable search and sort routines which were introduced
with commit a272858 from Ard Biesheuvel. This saves quite some memory in the
vmlinux binary with the 64bit kernel.

PA-RISC wants to sleep 5 seconds before panicking when panic_on_oops
is set, with no apparent reason. Remove this feature, since some users
may want their systems to fail as quickly as possible.
Users who want to delay reboot after panic can use PANIC_TIMEOUT.

On parisc and metag the stack grows upwards, so for those we need to
scan the stack downwards in order to calculate how much stack a process
has used.
Tested on a 64bit parisc kernel.

The system calls alloc_hugepages() and free_hugepages() were introduced
in Linux 2.5.36 and removed again in 2.5.54. They were never implemented
on parisc, so let's drop them now.

->export() might be called before we have done an update operation,

Crypto requests are not guaranteed to be finalized (->final() call),
and can be freed at any moment, without getting any notification from
the core. This can lead to memory leaks of the ->cache buffer.
Make this buffer part of the request object, and allocate an extra buffer
from the DMA cache pool when doing DMA operations.
As a side effect, this patch also fixes another bug related to cache
allocation and DMA operations. When the core allocates a new request and
import an existing state, a cache buffer can be allocated (depending
on the state). The problem is, at that very moment, we don't know yet
whether the request will use DMA or not, and since everything is
likely to be initialized to zero, mv_cesa_ahash_alloc_cache() thinks it
should allocate a buffer for standard operation. But when
mv_cesa_ahash_free_cache() is called, req->type has been set to
CESA_DMA_REQ in the meantime, thus leading to an invalind dma_pool_free()
call (the buffer passed in argument has not been allocated from the pool).

Message Manager is a hardware block used to communicate with various
processor systems within certain Texas Instrument's Keystone
generation SoCs.
This hardware engine is used to transfer messages from various compute
entities(or processors) within the SoC. It is designed to be self
contained without needing software initialization for operation.

Pull clk updates from Stephen Boyd:
"The clk changes for this release cycle are mostly dominated by new
device support in terms of LoC, but there has been some cleanup in the
core as well as the usual minor clk additions to various drivers.
Core:
- parent tracking has been simplified
- CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
- of_clk_init() doesn't consider disabled DT nodes anymore
- clk_unregister() had an error path bug squashed
- of_clk_get_parent_count() has been fixed to only return unsigned ints
- HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone
New Drivers:
- NXP LPC18xx creg
- QCOM IPQ4019 GCC
- TI dm814x ADPLL
- i.MX6QP
Updates:
- Cyngus audio clks found on Broadcom iProc devices
- Non-critical fixes for BCM2385 PLLs
- Samsung exynos5433 updates for clk id errors, HDMI support,
suspend/resume simplifications
- USB, CAN, LVDS, and FCP clks on shmobile devices
- sunxi got support for more clks on new SoCs and went through a
minor refactoring/rewrite to use a simpler factor clk construct
- rockchip added some more clk ids and added suport for fraction
dividers
- QCOM GDSCs in msm8996
- A new devm helper to make adding custom actions simpler (acked by Greg)"

This is a follow-up to renaming the directory in which this file lives from
shmobile to renesas which is in turn part of an ongoing process to migrate
from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that

This driver is a clk provider and not a clk consumer, so remove
the clk.h include. Also, drop clkdev.h because there's not clkdev
usage here either.

This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.
Along with the above mentioned Kconfig changes it seems appropriate
to also rename directories that only hold drivers for such SoCs.

cpg_div6_clock_set_rate() only programs the new divisor if the clock
isn't stopped. If the clock is stopped, it will update the cached
divisor value only, which will be programmed into the clock registers
when enabling the clock later.
However, cpg_div6_clock_recalc_rate() reads the divisor from the clock
registers instead of using the cached value, leading to an incorrect
result if the clock is currently stopped.
Make cpg_div6_clock_recalc_rate() use the cached value to fix this.
