John Stultz f5c9c9be26 sparc: Convert sparc to use read/update_persistent_clock
This patch converts the sparc architecture to use the generic
read_persistent_clock and update_persistent_clock interfaces, reducing
the amount of arch specific code we have to maintain, and allowing for
further cleanups in the future.

[ davem: compile fix: Here's a version that compiles, you have to get
  rid of the now unused variably last_rtc_update since we build with
  -Werror ]

John Stultz 0299b1371d sparc: convert to arch_gettimeoffset()
This patch converts sparc (specifically sparc32) to use GENERIC_TIME via
the arch_getoffset() infrastructure, reducing the amount of arch
specific code we need to maintain.

The sparc architecture is one of the last 3 arches that need to be
converted.

This patch applies on top of Linus' current -git tree

I've taken my best swing at converting this, but I'm not 100% confident
I got it right. My cross-compiler is now out of date (gcc4.2) so I
wasn't able to check if it compiled. Any assistance from arch
maintainers or testers to get this merged would be great.

Kristoffer Glembo fdd98ac96e sparc32: Remove early interrupt enable.
Enabling interrupts at this points causes the warning
"start_kernel(): bug: interrupts were enabled early"
to be printed in start_kernel().

Sam Ravnborg 6943f3da3e sparc: move EXPORT_SYMBOL to the symbols definition
Move all applicable EXPORT_SYMBOL()s to the file where the respective
symbol is defined.

Removed all the includes that are no longer needed in sparc_ksyms_32.c

Comment all remaining EXPORT_SYMBOL()s in sparc_ksyms_32.c

Two symbols are shared with sparc64 thus the exports were removed from
the sparc_ksyms_64.c too, along with the include their ommission made
redundant.

Additions by Julian Calaby:
* Moved EXPORT_SYMBOL()s for prom functions to their rightful places.
* Made some minor cleanups to the includes and comments of sparc_ksyms_32.c
* Made another subtraction from sparc_ksyms_64.c
* Updated and tidied commit message.
* Rebased patch over sparc-2.6.git HEAD.
* Ensured that all modified files have the correct includes.

Sam Ravnborg d670bd4f80 sparc: prepare kernel/ for unification
o sparc32 files with identical names to sparc64 renamed to <name>_32.S
o introduced a few Kconfig helpers to simplify Makefile logic
o refactored Makefile to prepare for unification
  - use obj-$(CONFIG_SPARC32) for sparc32 specific files
  - use <name>_$(BITS) for files where sparc64 has a _64 variant
  - sparc64 directly include a few files where sparc32 builds them,
    refer to these files directly (no BITS)
  - sneaked in -Werror as used by sparc64
o modified sparc/Makefile to use the new names for head/init_task
