Peter Zijlstra f2c4db1bd8 x86/cpu: Sanitize FAM6_ATOM naming
Going primarily by:

  https://en.wikipedia.org/wiki/List_of_Intel_Atom_microprocessors

with additional information gleaned from other related pages; notably:

 - Bonnell shrink was called Saltwell
 - Moorefield is the Merriefield refresh which makes it Airmont

The general naming scheme is: FAM6_ATOM_UARCH_SOCTYPE

	sed -i  -e 's/ATOM_PINEVIEW/ATOM_BONNELL/g'		\

platform_get_irq() returns an error code, but the intel_mid_powerbtn

Sudeep Holla daea5a65de intel_mid_powerbtn: Remove misuse of IRQF_NO_SUSPEND flag
The IRQF_NO_SUSPEND flag is used to identify the interrupts that should
be left enabled so as to allow them to work as expected during the
suspend-resume cycle, but doesn't guarantee that it will wake the system
from a suspended state, enable_irq_wake is recommended to be used for
the wakeup.

This patch removes the use of IRQF_NO_SUSPEND flags and uses newly
introduce PM wakeup APIs dev_pm_{set,clear}_wake_irq.

This change removes the use of __devinit, __devexit_p, __devinitdata,

Michael Demeter 7714567c87 intel_mid_powerbtn: use MSIC read/write instead of ipc_scu
In the 2.6.36 kernel we did not have the MSIC driver. Changed
all ipc_scu_reads/writes to use the MSIC driver and defines.
Added a fix from the 2.6.36 kernel where the SCU FW could send
a power button interrupt to the IA32 FW and the kernel was not
running yet. This resulted in the interrupt not getting cleared
and the power button was ignored. this fix just clears the
interrupt on start-up.
