The "strictlimit" feature was introduced to enforce per-bdi dirty limits
for FUSE which sets bdi max_ratio to 1% by default:
http://article.gmane.org/gmane.linux.kernel.mm/105809
However the feature can be useful for other relatively slow or untrusted
BDIs like USB flash drives and DVD+RW. The patch adds a knob to enable
the feature:
echo 1 > /sys/class/bdi/X:Y/strictlimit
Being enabled, the feature enforces bdi max_ratio limit even if global
(10%) dirty limit is not reached. Of course, the effect is not visible
until /sys/class/bdi/X:Y/max_ratio is decreased to some reasonable value.

788257d6101d9 ("ufs: remove the BKL") replaced BKL with mutex protection
using functions lock_ufs, unlock_ufs and struct mutex 'mutex' in sb_info.
b6963327e052 ("ufs: drop lock/unlock super") removed lock/unlock super and
added struct mutex 's_lock' in sb_info.
Those 2 mutexes are generally locked/unlocked at the same time except in
allocation (balloc, ialloc).
This patch merges the 2 mutexes and propagates first commit solution. It
also adds mutex destruction before kfree during ufs_fill_super failure and
ufs_put_super.

Since 4dcfa600 ("ARM: DMA-API: better handing of DMA masks for coherent
allocations") arm_dma_limit_pfn has almost substituted the arm_dma_limit.
The remaining user is dma_contiguous_reserve(). It is also referenced in
setup_dma_zone() to calculate arm_dma_limit_pfn.
Kill the global arm_dma_limit and equip setup_zone_dma with the local one.

Currently, memsetting and kfreeing the device is bad behaviour. The
device will have a reference count of 1 and hence can cause trouble
because it has kfree'd. Proper way to handle a failed device_register is
to call put_device right after it fails.

Unbreak i386 allmodconfig.
This is a hack - please fix properly ;)
