Patch from Deepak Saxena
The current memset() and memzero() macros on ARM reference the
incoming parameters more than once and this can cause uninted
side-effects. The issue was found while debugging SCTP protocol
and with the specific usage of memzero(skb_put(skb,size),size).
This call would call skb_put(skb,size) twice leading to badness.
The fixed version copies the incoming parameters into local
variables and uses those instead.

The S3C2400 doesn't have a cpuid information stored anywhere. This patch adds
support to the S3C2400 at include/asm-arm/arch-s3c2400/uncompress.h by
initializing the cpuid variable to the S3C2410, as they share the same
routine. The GSTATUS1 pin is then used only if not compiling for the S3C2400.

(!ARCH_S390 && !M68K && !IA64 && !UML) is obviously always true on ARM.
Intended behaviour for ARM is "absent unless we are on RiscPC or
EBSA285". So what we want is added && !ARM in the first term - without
it the last part (|| ARCH_RPC || ARCH_EBSA285, that is) doesn't do

Turns __get_unaligned() and __put_unaligned into macros. That is
definitely safe; leaving them as inlines breaks on e.g. alpha [try to

CONFIG_HW_CONSOLE selects vt.c; without the stuff pulled by CONFIG_VT it
will not build. Normally we get both in drivers/char/Kconfig and there
HW_CONSOLE depends on VT. sparc64 does not pull drivers/char/Kconfig
and has that sutff in arch/sparc64/Kconfig instead. However, it forgets
to add the same dependency. As the result, turning VT off [which is
possible] will end up with broken build. For no good reason...

This patch is required to support cpu removal for IPF systems. Existing code
just fakes the real offline by keeping it run the idle thread, and polling
for the bit to re-appear in the cpu_state to get out of the idle loop.
For the cpu-offline to work correctly, we need to pass control of this CPU
back to SAL so it can continue in the boot-rendez mode. This gives the
SAL control to not pick this cpu as the monarch processor for global MCA
events, and addition does not wait for this cpu to checkin with SAL
for global MCA events as well. The handoff is implemented as documented in
SAL specification section 3.2.5.1 "OS_BOOT_RENDEZ to SAL return State"

We were forgetting to call sunsu_change_speed(). The reason
that replugging in the mouse cable "fixes things" is that
causes a BREAK interrupt which in turn caused a call to
sunsu_change_speed() which would get the chip setup properly.

Provide support for drivers/char/rtc.c ioctls in the
Mostek rtc driver as well as the Sparc specific RTCGET
and RTCSET.
This allows userspace to be much less messy. Currently
util-linux and other spots jump through hoops trying
various ioctl variants until it hits the right one whatever
driver actually being used supports.
Eventually all of this should move over to the genrtc.c
driver, but not today...
While we are here, fix up the register types for sparse.
