re-initialize the CPUs exception banked registers via that code rather
than having platforms deal with that level of detail. So, move the
call to cpu_init() out of platform code into core code.

We don't need a veneer for cpu_suspend, it can be called directly from
C code now. Move it into sa11x0_pm_enter() along with the re-enabling
of clock switching.

Move the call to cpu_suspend into C code, and noticing that all the
s3c_cpu_save implementations are now identical, we can move this
into the common samsung code.

The core suspend code calls flush_cache_all() immediately prior to
calling the suspend finisher function, so remove these needless calls
from the finisher functions.

We don't need a veneer for cpu_suspend, it can be called directly from

The ABI allows called functions to corrupt r0-r3 and ip (r12). So
its pointless saving these registers in the suspend code - the
calling function will expect them to be corrupted and so won't rely
on their contents after resume.

The code alludes to r9 being used to indicate what was lost over the
suspend/resume transition. However, although r9 is set, it is never
actually used.
Also, the comments before the code (which refer to the value of r9)
and the comments against the assignment of r9 contradict each other,
so just

before we resume normal operations. This ensures that userspace

Hi Paul,
Here are the latest bug fixes done on the hwmod framework.
There are mainly around wakeup capability added in OMAP4.
The series is based on for_3.0.1/2_prcm_files_cleanup and tested
on OMAP4430 ES2.1 + SDP.
The patches are available here:
