The C-state idle time is not calculated correctly, which will return the wrong

1. The system can't choose the deeper C-state when it is idle next time.
Of course the system power is increased. E.g. On one server machine about 40W

2. The powertop shows that it will stay in C0 running state about 95% time

i2c: Remove all i2c_set_clientdata(client, NULL) in drivers
I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers.
As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

xen: ensure timer tick is resumed even on CPU driving the resume
The core suspend/resume code is run from stop_machine on CPU0 but
parts of the suspend/resume machinery (including xen_arch_resume) are
run on whichever CPU happened to schedule the xenwatch kernel thread.
As part of the non-core resume code xen_arch_resume is called in order
to restart the timer tick on non-boot processors. The boot processor
itself is taken care of by core timekeeping code.
xen_arch_resume uses smp_call_function which does not call the given
function on the current processor. This means that we can end up with
one CPU not receiving timer ticks if the xenwatch thread happened to
be scheduled on CPU > 0.
Use on_each_cpu instead of smp_call_function to ensure the timer tick

libata: implement on-demand HPA unlocking
Implement ata_scsi_unlock_native_capacity() which will be called
through SCSI layer when block layer notices that partitions on a
device extend beyond the end of the device. It requests EH to unlock
HPA, waits for completion and returns the current device capacity.
This allows libata to unlock HPA on demand instead of having to decide
whether to unlock upfront. Unlocking on demand is safer than
unlocking by upfront because some BIOSes write private data to the
area beyond HPA limit. This was suggested by Ben Hutchings.

at 'perf record' time we used __perf_session__process_events and that

entries to the global DSO list _after_ removing the current directory
from the DSO name, for presentation purposes.
Because of that we end up having two entries in the DSO list when
recording events for binaries using relative pathnames.
Fix it minimally by setting symbol_conf.full_paths to true when marking
the DSOs with hits in 'perf buildid-list --with-hits', as used by 'perf
archive'
Right fix longer term is to shorten the path only at presentation time.
Will be done for 2.6.36.

cifs: fix page refcount leak
Commit
315e995c63a15cb4d4efdbfd70fe2db191917f7a is causing OOM kills
when stress-testing a CIFS filesystem. The VFS readpages operation takes
a page reference. The older code just handed this reference off to the
page cache, but the new code takes an extra one. The simplest fix is to
put the new reference after add_to_page_cache_lru.

fix cpu_chain section mismatch...
In commit
e9fb7631ebcd ("cpu-hotplug: introduce cpu_notify(),
__cpu_notify(), cpu_notify_nofail()") the new helper functions access
cpu_chain. As a result, it shouldn't be marked __cpuinitdata (via
section mismatch warning).
Alternatively, the helper functions should be forced inline, or marked
__ref or __cpuinit. In the meantime, this patch silences the warning
the trivial way.
