set_cp0_* and change_cp0_* which makes the kernel code somewhat more
readable. Going through the kernel code I notices some stupid abuse of
the old function like set_cp0_status(ST0_BEV, 1) - this clear ST0_BEV
but actually looks like attempting to set it and other abuses, so will
people please look over their code again.

binaries. For 64-bit kernel and 32-bit the higher 32-bit of addresses
have to be stripped of all addresses.

of rejects to fixup while integrating Linus patches. I also found
that this kernel will only boot SMP on Origin; the UP kernel freeze
soon after bootup with SCSI timeout messages. I commit this anyway
since I found that the last CVS versions had the same problem.

o only code for the configured CPU is compiled
and linked (saves ~100k for R3000 kernels!)
o removed a lot of indirect function calls
o removed Ralf's "cowboy patch"
o added sanity check for DECstations (print warning
if the kernel is configured for the wrong CPU)

o New clear_user.
o Memcpy now efficiently copies the (src^dest)&3 != 0.
o Memmove new correctly deals with overlaps
o Rewrite csum_partial in assembler.
o Rewrte csum_partial_from_user in assembler.
o __copy_user is now integrated with memcpy.
o get_user now returns a zero value on error.
o copy_from_user now clears the destination buffer on error.
o strncpy_user now has a more efficient caller routine.
o strlen_user now has a more efficient caller routines and is faster.
o The unaligned handler is now much cleaner. It's now also save from
interrupt. Some more esotheric bugs fixed as well.
o Don't export bcopy anymore, it's now a inline function.
o Delete ancient junk from the first days of Linux/MIPS.
o Delete dead code in indy_sc.c.
o Including the IDE driver doesn't crash an Indy anymore.
o Eleminate active_ds. We now use current_ds directly in the thread
structure which is faster and threadsafe. Saves almost 2kb on the
kernel.
o Serial console should work again.

o First round of bugfixes for the SC/MC CPUs.
o FPU context switch fixes.
o Lazy context switches.
o Faster syscalls.
o Removed dead code.
o Shitloads of other things I forgot ...

Pentium :-)
o Little bit smarter handling of unimplemented exceptions.
o Fix FPU context switches.
o Fix reboot / halt. Powerdown in software still doesn't work.
o Fix the fix for handling of return values of interrupted syscalls.
o Handling of the Indy second level cache now works as spec'ed. Purely
cosmentic, this was not causing any problems.

o Just count missed heartbeats on Indys but don't print a messages. This
was a bug by itself.
o Fix a crash in exit_mmap().
o Fix scanmem().
o Fix clear_active_bh(), a ~ was missing causing weak performance.
o Remove experimental cache instructions from stackframe.h. It wasn't
improving performance as I was hoping.
o Shrink the size of the exception handler routines in uaccess.h.
o Cleanup, remove dead code in various files.
