This commit adds pullup method implementation for UDC s3c-hsotg driver.
It is needed for e.g. CCG - Configurable Composite Gadget, when user space
configuration change request device disconnection from USB bus (done via
calling usb_gadget_connect/disconnect, which calls UDC's pullup method).
Implementation of pullup method has caused removal of phy_enable and
core_init methods from udc_start to pullup.

Currently, when a new value is stored to the “file” sysfs entry,
fsg_store_file() will release existing backing file and only then attempt to
open a new one. If that fails, no new backing file is open.
This commit changes the fsg_lun_open() so that it closes existing backing file
only after the new backing file has been successfully opened. With that
change, fsg_store_file() may use it to perform an atomic open operation with
guarantee that logical unit will either point to the new backing file or still
to the old one.

As per the OMAP4 documentation, audio over HDMI must be transmitted in
no-idle mode. This patch adds the HWMOD_SWSUP_SIDLE so that omap_hwmod uses
no-idle/force-idle settings instead of smart-idle mode.
This is required as the DSS interface clock is used as functional clock
for the HDMI wrapper audio FIFO. If no-idle mode is not used, audio could
be choppy, have bad quality or not be audible at all.

Until the OMAP4 code is converted to disable the use of the clock
framework-based clockdomain enable/disable sequence, any clock used as
a hwmod main_clk must have a clockdomain associated with it. This
patch populates some clock structure clockdomain names to resolve the
following warnings during kernel init:
omap_hwmod: dpll_mpu_m2_ck: missing clockdomain for dpll_mpu_m2_ck.
omap_hwmod: trace_clk_div_ck: missing clockdomain for trace_clk_div_ck.

Commit de1cbee which removed b_file_offset in favor of b_bn introduced a bug
causing xfs_buf_allocate_memory() to overestimate the number of necessary
pages. The problem is that xfs_buf_alloc() sets b_bn to -1 and thus effectively
every buffer is straddling a page boundary which causes
xfs_buf_allocate_memory() to allocate two pages and use vmalloc() for access
which is unnecessary.
Dave says xfs_buf_alloc() doesn't need to set b_bn to -1 anymore since the
buffer is inserted into the cache only after being fully initialized now.
So just make xfs_buf_alloc() fill in proper block number from the beginning.

An inode in the AIL can be flush locked and marked stale if
a cluster free transaction occurs at the right time. The
inode item is then marked as flushing, which causes xfsaild
to spin and leaves the filesystem stalled. This is
reproduced by running xfstests 273 in a loop for an
extended period of time.
Check for stale inodes before the flush lock. This marks
the inode as pinned, leads to a log flush and allows the
filesystem to proceed.

The OProfile perf backend uses a static array to keep track of the
perf events on the system. When compiling with CONFIG_CPUMASK_OFFSTACK=y
&& SMP, nr_cpumask_bits is not a compile-time constant and the build
will fail with:
oprofile_perf.c:28: error: variably modified 'perf_events' at file scope
This patch uses NR_CPUs instead of nr_cpumask_bits for the array
initialisation. If this causes space problems in the future, we can
always move to dynamic allocation for the events array.

There is some concern that these iput()'s could be the final iputs and could
induce lockups on people waiting on writeback. This would happen in the
rare case that we don't create ordered extents because of an error, but it
is theoretically possible and we already have a mechanism to deal with this
so just make them delayed iputs to negate any worry.

add_all_parents did assume that path is already at a correct extent data
item, which may not be true in case of data extents that were partly
rewritten and splitted.
We need to check if we're on a matching extent for every item and only
for the ones after the first. The loop is changed to do this now.
This patch also fixes a bug introduced with commit 3b127fd8 "Btrfs:
remove obsolete btrfs_next_leaf call from __resolve_indirect_ref".
The removal of next_leaf did sometimes result in slot==nritems when
the above described case happens, and thus resulting in invalid values
(e.g. wanted_obejctid) in add_all_parents (leading to missed backrefs
or even crashes).

The final formal of migrate_pages() is a mode of type enum migrate_mode,
