This should eventually squash down to: [audit: log namespace serial numbers]

Use a more current logging style.
Convert the remaining printks without a KERN_
to pr_ where appropriate.
There a few additional printks without a level that
are emitted at KERN_DEFAULT for stack dumps and such.
Add printf format/argument verification to the static
inline just in case.
These are now unused so delete them.

Commit 1e434f9318efc3dddc0c0b8d2071712668154c2b (OMAPFB: remove early mem
alloc from old omapfb) deleted the support for early fbmem allocation
from the platform code, but some code still remains in the driver side.
Delete this code now, as it repotedly causes build issues on !MMU.

https://lkml.org/lkml/2010/6/15/147
This patch would have fixed the apbfreq not being a real struct member
and would also explain why clk_get_rate is called without using it's
return value in the line above what you have.

To implement the context tracker properly on arm64,
a function call needs to be made after debugging and
interrupts are turned on, but before the lr is changed
to point to ret_from_exception(). If the function call
is made after the lr is changed the function will not
return to the correct place.
Make calls to ct_user_enter when the kernel is exited
and ct_user_exit when the kernel is entered (in el0_da,
el0_ia, el0_svc, el0_irq and all of the "error" paths).
These macros expand to function calls which will only work
properly if el0_sync and related code has been rearranged

a prerequisite for FULL_NOHZ support). This patchset
builds upon earlier work by Kevin Hilman and is based on 3.15-rc2.

Hi,
In some testing I ran today, we end up spending 40% of the time in
filemap_check_errors(). That smells fishy. Looking further, this is
basically what happens:
blkdev_aio_read()
generic_file_aio_read()
filemap_write_and_wait_range()
if (!mapping->nr_pages)

Hello,
Currently, while csses (cgroup_subsys_states) have ->parent linkage
too, only cgroups form full tree through their ->children and
->sibling fields and css iterations naturally is implemented by
iterating cgroups and then dereferencing the css for the specified
subsystem.
There are now use
mem_cgroup_force_empty() is used only from
mem_cgroup_force_empty_write() and tests whether the target memcg has
any tasks or children without any synchronization and then returns
-EBUSY if so.
This is just weird. The tests don't really mean anything as tasks and
children may be added after the
