Remove the special handling for the Data TLB entry dirty bit in the TLB-miss
handler. As the code stands, all that it does is to cause us to take a second
data address exception to set the dirty bit. Instead, we can just let
pte_mkdirty() set the bit.

Implement the TIF_NOTIFY_RESUME thread flag, making it call do_notify_resume()

This adds the back-end for the PMU on POWER7 processors. POWER7
has 4 fully-programmable counters and two fixed-function counters
(which do respect the freeze conditions, can generate interrupts,
and are writable, unlike PMC5/6 on POWER5+/6).

the only use of those GPIO are IRQs and IRQ code does setup GPIO

This patch introduces three boot options (no_cmci, dont_log_ce
and ignore_ce) to control handling for corrected errors.
The "mce=no_cmci" boot option disables the CMCI feature.
Since CMCI is a new feature so having boot controls to disable
it will be a help if the hardware is misbehaving.
The "mce=dont_log_ce" boot option disables logging for corrected
errors. All reported corrected errors will be cleared silently.
This option will be useful if you never care about corrected
errors.
The "mce=ignore_ce" boot option disables features for corrected
errors, i.e. polling timer and cmci. All corrected events are
not cleared and kept in bank MSRs.
Usually this disablement is not recommended, however it will be
a help if there are some conflict with the BIOS or hardware
monitoring applications etc., that clears corrected events in
banks instead of OS.

Now that the dependent patches are merged, we are ready to enable

This fixes up a typo in the ll/sc based cmpxchg code which apparently

that fixed up, the ll/sc code also starts using it and provides its own
