The problem is that currently none of the clocks are being registered for
OMAP4470 devices and so on boot-up no clocks can be found and the kernel panics.
This fix allows the kernel to boot without failure using a simple RAMDISK file
system on OMAP4470 blaze board.
Per feedback from Paul and Benoit the 4470 clock data is incomplete for new
modules such as the 2D graphics block that has been added to the 4470.
Therefore add a warning to indicate that the clock data is incomplete.

Iteration over all power domains in the idle path is unnecessary since
only power domains that are transitioning need to be accounted for.
Also PRCM register accesses are known to be expensive, so the
additional latency added to the idle path is signficiant.
In order allow the pre/post transitions to be isolated and called

trigger the pre/post transtion accounting for only that specific power
domain. Passing NULL means iterating over all power domains as is

IO Daisychain feature has to be triggered whenever there is a change in

Now devices can idle independent of the powerdomain, there can be a

enabled at padlevel as well as io daisychain sequence is triggered,
there will be 2 PRCM interrupts (Module async wake up via swakeup and

[b] Clear PM_WKEN_WKUP.EN_IO bit
[c] Clear PM_WKST_WKUP.ST_IO bit by writing 1 to it.

Btrfs: don't assume to be on the correct extent in add_all_parents
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).

mm/memblock: fix overlapping allocation when doubling reserved array
__alloc_memory_core_early() asks memblock for a range of memory then try
to reserve it. If the reserved region array lacks space for the new
range, memblock_double_array() is called to allocate more space for the
array. If memblock is used to allocate memory for the new array it can
end up using a range that overlaps with the range originally allocated in
__alloc_memory_core_early(), leading to possible data corruption.
With this patch memblock_double_array() now calls memblock_find_in_range()
with a narrowed candidate range (in cases where the reserved.regions array
is being doubled) so any memory allocated will not overlap with the
original range that was being reserved. The range is narrowed by passing
in the starting address and size of the previously allocated range. Then
the range above the ending address is searched and if a candidate is not
found, the range below the starting address is searched.

The original reason has gone away after the previous patch, ->children
list must be empty after zap_pid_ns_processes().
However now we can not switch to init_pid_ns.child_reaper.
__unhash_process() relies on the "->child_reaper == parent" check, but
this check does not work if the last exiting task is also the child
reaper.
As Eric sugested, we can change __unhash_process() to use the parent's
pid_ns and remove this code.

pidns: guarantee that the pidns init will be the last pidns process reaped
Today we have a twofold bug. Sometimes release_task on pid == 1 in a pid
namespace can run before other processes in a pid namespace have had
release task called. With the result that pid_ns_release_proc can be
called before the last proc_flus_task() is done using upid->ns->proc_mnt,
resulting in the use of a stale pointer. This same set of circumstances
can lead to waitpid(...) returning for a processes started with
clone(CLONE_NEWPID) before the every process in the pid namespace has
actually exited.
To fix this modify zap_pid_ns_processess wait until all other processes in
the pid namespace have exited, even EXIT_DEAD zombies.
The delay_group_leader and related tests ensure that the thread gruop
leader will be the last thread of a process group to be reaped, or to
become EXIT_DEAD and self reap. With the change to zap_pid_ns_processes
we get the guarantee that pid == 1 in a pid namespace will be the last
task that release_task is called on.
With pid == 1 being the last task to pass through release_task
pid_ns_release_proc can no longer be called too early nor can wait return
before all of the EXIT_DEAD tasks in a pid namespace have exited.
