This patch fixes a bunch of UML bugs -
crashes caused by excessive stack usage, plus assiciated cleanups
SA_SIGINFO signal delivery is fixed, making JVMs run a lot better
skas mode now has protection against tmpfs filling up
the initial UML thread is protected against running kernel code
a couple of data corruption bugs are fixed

This fixes a number of UML bugs -
fixes a crash in the network seen with slab poisoning
fixes a timer bug and cleans up the code
changes how IRQs are disabled and enabled
fixes the semantics of PROT_NONE
adds asm/xor.h so that raid drivers will build

xor.h was created as asm-um/xor.h rather than include/asm-um/xor.h.
Fixed.
ChangeSet@1.668, 2002-10-02 12:04:54-04:00, jdike@uml.karaya.com
Back out a piece of the last merge which didn't apply in 2.5.
ChangeSet@1.667, 2002-10-02 11:39:20-04:00, jdike@uml.karaya.com
A small network bug fix from 2.4.19-7.
ChangeSet@1.666, 2002-10-02 10:23:50-04:00, jdike@uml.karaya.com

ChangeSet@1.579.15.1, 2002-09-23 20:38:01-04:00, jdike@uml.karaya.com
A number of bug fixes from UML 2.4.19-6 -
Fixed the net crash seen when slab debugging is enabled
Fixed PROT_NONE
Fixed the 'tracing myself' bug seen on umlcoop. This was caused by
a number of SIGALRM handlers nesting on the idle thread stack because
the system was busy enough that UML couldn't clear one before the
next arrived.
