If CONFIG_BUILD_ELF64 was not selected and gcc had -msym32 option
(i.e. 4.0 or newer), there is no point to use %highest, %higher for
kernel symbols.
This patch also fixes 64-bit SMTC version of get_saved_sp() which is
broken but harmless since there is no such CPUs for now.
A bonus is set_saved_sp() and SMP version of get_saved_sp() are more
readable now.

This option is no longer usable with supported compilers. It will be
replaced by usage of -msym32 in a separate patch.

TLB handlers a bit, match definitions in pgtable-{32,64}.h better.

binutils are broken and don't warn about this use of $at even though
gas is in .set noat mode so this for now is an accident waiting to
happen.

Removed obsolete stuff from arch makefile.
mips had a special rule for generating asm-offsets.h so preserved it
using an architecture specific hook in top-level Kbuild file.
Renamed .h file to asm-offsets.h

Update the generic MIPS code. Highlights are oprofile for MIPS, initially for
the PMC-Sierra RM9000. We're also taking a significantly more aggressive
approach to the TLB exception handlers which now are runtime generated and
provide an upto 20% speedup on certain micro benchmarks.

o General updates of MIPS to 2.6.10-rc2
o Remove the Baget platform due to lack of maintenance over several years.
Some of the drivers remain and will be removed in a separate patch.
o Remove the HP Laserjet platform. No user reports ever and no patches from
the original submitters made this port a neat hack - and a directory full
of clutter.
o SMP support for the PMC-Sierra.

MIPS update:
- Further conversion of MIPS kernel configuration to reverse dependencies.
- Support for the PMC-Sierra Yosemite evaluation board.
- Merge arch/mips/mm-32 and arch/mips/mm-32 into arch/mips/mm.
- Partial support for the R8000 now that I finally have clearance for the
documentation previously covered by NDA.
- Make distclean fixes.
- Regenerate default configuration files against latest Kconfig files.
- Fix handling of data bus errors in modules.
- Make R4000 bug probing more bullet proof.
- Rewrite semaphore code folloing the PPC implementation to no longer
manipulate 2 32-bit quantities atomically using 64-bit instructions.
Occasionally this did cause problems due to struct semaphore not having
sufficient alignment.
- Make sys_pipe() code bullet proof against gcc 3.5 over-optimization.
- Fix possibly exploitable bug in IRIX compatibility statvfs(2).
- Make sched_clock() an outline function.
- Support for the MIPS 24K and 25K processors.
- Make functions static that aren't needed anywhere else.
- Factor out some more generic MIPS SMP code.
- Factor out common part of the GT-64240 code.
- Ocelot C now uses the generic MV-64340 interrupt handler code.
- Factor out common board support code
- More cleanup and bug fixes for the NEC VR41xx code.
- Start cleanup of hazard handling as required for MIPS32/64 V2 processors.
- Enforce minimal kmalloc alignment of 8 byte so 64-bit registers can be
stored into fields without exceptions.
- Speeling and warning fixes.

Below following 125547 lines of patches, all to arch/mips and
include/asm-mips. I'm going to send the remaining stuff of which the one
or other bit may need to be discussed in smaller bits.

Here's another MIPS update. The patch is huge because it completly
folds mips64 into mips, thereby eleminating 41010 lines of code.
|
|
This contains all the generic 32-bit MIPS code, so all arch/mips/ and
include/asm-mips/ stuff.

- make sure "sync()" doesn't effectively lock up the machine by
overloading all the IO resources
- fix up some network memory allocations that don't wan tto wait on IO.
- merge with Alan (including MIPS update)
- Jeff Garzik: network driver updates.
- Al Viro: System V FS update (write capability, page cache, mondo cleanups)
- Kai Germaschewski: ISDN cleanups, TURBOPAM driver by Stelian Pop
- Ben Fennema: UDF update (time handling, i_blocks fix)
- Neil Brown: md error handling improvements, knfsd file handle compatibility
- Paul Mackerras: PPC update
- Jakub Jelinek: fix up kernel linker scripts to accept .rodata better
- Patrick Mochel: fix PME handling in pci_enable_wake()
- Chris Mason: reiserfs PF_MEMALLOC handling
