[media] s5p-mfc: Remove special clock usage in driver
MFC uses two clocks - MFC gate clock and special clock
which is named as "sclk_mfc" in exynos4 and "aclk_333" in
exynos5 SoC. The driver was doing just a clk_prepare on
this special clock without a clk_enable call. As this
sclk is the parent of gate clock, it gets prepared and
enabled along with the gate clock. So there is no need
for the driver to use this sclk. This patch removes the
sclk usage from driver.

The reason for the crash is that '__efivars' hasn't been initialised nor
has it been registered with register_efivars() by the time the google
EFI SMI driver runs. The gsmi code uses its own struct efivars, and
therefore, a different variable list. Fix the above crash by passing

parisc: use spin_lock_irqsave/spin_unlock_irqrestore for PTE updates
User applications running on SMP kernels have long suffered from instability
and random segmentation faults. This patch improves the situation although
there is more work to be done.
One of the problems is the various routines in pgtable.h that update page table
entries use different locking mechanisms, or no lock at all (set_pte_at). This
change modifies the routines to all use the same lock pa_dbit_lock. This lock
is used for dirty bit updates in the interruption code. The patch also purges
the TLB entries associated with the PTE to ensure that inconsistent values are
not used after the page table entry is updated. The UP and SMP code are now
identical.
The change also includes a minor update to the purge_tlb_entries function in
cache.c to improve its efficiency.

parisc: disable -mlong-calls compiler option for kernel modules
CONFIG_MLONGCALLS was introduced in commit
ec758f98328da3eb933a25dc7a2eed01ef44d849 to overcome linker issues when linking
huge linux kernels, e.g. with many modules linked in.
But in the kernel module loader there is no support yet for the new relocation
types, which is why modules built with -mlong-calls can't be loaded.
Furthermore, for modules long calls are not really necessary, since we already
use stub sections which resolve long distance calls.

in the following compiler warnings:

Memory maps typically require that the buffer size to be page

Also, the buffer overflow check doesn't take it into account.
So, instead of doing it at each memops driver, enforce it at
