power management changes for omap and imx

Cleanups for the Samsung platforms

drivers/tty/serial/Kconfig both due to just adding code close to
changes.
Cleanups on various subarchitectures
Cleanup patches for various ARM platforms and some of their associated
drivers, the bulk of these is for mach-91.
Arnd ended up pulling in the restart branch from Russell in order to
fix up some simple but annoying merge conflicts.

Non-critical bug fixes
Simple bug fixes that were not considered important enough for inclusion
into 3.2.
* tag 'fixes-non-critical' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
MAINTAINERS: update pxa and mmp

ARM: OMAP2+: DMA: Workaround for invalid source position
* 'for-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu:
percpu: Remove irqsafe_cpu_xxx variants
Fix up conflict in arch/x86/include/asm/percpu.h due to clash with
cebef5beed ("x86: Fix and improve percpu_cmpxchg{8,16}b_double()")
which edited the (now removed) irqsafe_cpu_cmpxchg*_double code.
Commit 2f0778afa (ARM: 7205/2: sched_clock: allow sched_clock to be
selected at runtime) replaced the picoxcell specific sched_clock() with
a generic runtime selectable version but replaced "unsigned long long
notrace sched_clock(void)" with "unsigned u32 notrace
picoxcell_read_sched_clock(void)" fix this up to return a u32 as
expected.

The renesas_usbhs driver doesn't use the clk functions. So, even if we
adds "CLKDEV_DEV_ID("renesas_usbhs.0", ...)" only, we cannot use the USB
controller because clk_late_init() will disable the clock by "usb0".
So, the patch also removes the "CLKDEV_CON_ID("usb0", ...)".
