[uml-devel] uml-patch-2.4.18-22

[Jeff D. <jd...@ka...>]

This patch fixes a few signal delivery bugs, including the non-existence
of sys_rt_sigreturn and a crash when a sigreturn happened without a signal
deliver preceding it.

These fixes allow UML to run nested.  See 
	http://user-mode-linux.sf.net/nesting.html
for the details.

SIGCHLD is now ignored by the idle thread.  This fixes a crash caused by
a helper exiting in the context of the idle thread.

Fixed the code which reads /proc/cpuinfo to handle EOF properly.

KSTK_EIP and KSTK_ESP are now implemented, so the IP and SP fields of
/proc/<pid>/stat now have real values.
