Gcc might emit an absolute address for the the "m" constraint which
gas unfortunately does not permit.

Saves like 1,600 lines of code, is way easier to debug, compilers
frequently do a better job than the cut and paste type of handlers many
boards had. And finally having all the stuff done in a single place
also means alot of bug potencial for the MT ASE is gone.
The only surviving handler in assembler is the DECstation one; I hope
Maciej will rewrite it.

Some things were renamed because the PPC variant of the MV-643XX now
uses the same header and the Jaguar code didn't catch up on that.

Came up through a quick grep for other cases similar to the ftruncate()
one in commit 0a489cb3b6.
Also, add a comment, so that people who read the code understand why we
do what looks like a no-op.
(Again, this won't actually matter to any sane user, since libc will
save and restore the register gcc stomps on, but it's still wrong to
stomp on it)

Gcc thinks it owns the incoming argument stack, but that's not true for
"asmlinkage" functions, and it corrupts the caller-set-up argument stack
when it pushes the third argument onto the stack. Which can result in
%ebx getting corrupted in user space.
Now, normally nobody sane would ever notice, since libc will save and
restore %ebx anyway over the system call, but it's still wrong.
I'd much rather have "asmlinkage" tell gcc directly that it doesn't own
the stack, but no such attribute exists, so we're stuck with our hacky
manual "prevent_tail_call()" macro once more (we've had the same issue
before with sys_waitpid() and sys_wait4()).
Thanks to Hans-Werner Hilse <hilse@sub.uni-goettingen.de> for reporting
the issue and testing the fix.

tee was already there for some reason for native 64bit, but
sys_sync_file_range was missing. Also add it to the compat layer.

Needed for some big Opteron systems to compute a numa hash function
They have more than 12 bits significant address.
TBD switch this over to dynamic allocation or use better hash

o Start booting into the capture kernel after an Oops if system is in a
unrecoverable state. System will boot into the capture kernel, if one is
pre-loaded by the user, and capture the kernel core dump.
o One of the following conditions should be true to trigger the booting of
capture kernel.
- panic_on_oops is set.
- pid of current thread is 0
- pid of current thread is 1
- Oops happened inside interrupt context.

The patch I submitted earlier to fix disabled LAPIC handling in ACPI
was mismerged for some reason I still don't quite understand. Parts
of it was applied to the wrong function.
This patch fixes it up.
