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]

For samsung platforms, remove the include of mach/system-reset.h and

just define their arch_reset functions. As a result, the s3c2410 and

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.

1. map 4 pages of a file at offset 0

2. map 2 pages just after the first mapping of the same file but with
page offset 2
[0123][23]

|01|
mbind vma
Oops. then, it makes wrong vma merge and splitting ([01][0123] or similar).

gspca: Fix bulk mode cameras no longer working (regression fix)
The new iso bandwidth calculation code accidentally has broken support
for bulk mode cameras. This has broken the following drivers:
finepix, jeilinj, ovfx2, ov534, ov534_9, se401, sq905, sq905c, sq930x,
stv0680, vicam.
Thix patch fixes this. Fix tested with: se401, sq905, sq905c, stv0680 & vicam
cams.
