Message-Id: <20080424.040239.193699673.davem@davemloft.net>

Subject: [GIT]: Sparc
Several Sparc updates for 2.6.26:
1) NUMA support, detection is added for Niagara machines.
Support for detection on older systems will be forthcoming.
2) Make use of an unused field in pt_regs to store both
a magic number, and the trap number, this allows:
a) Removing the funny passing of the "restart_syscall"
boolean in the trap return paths to the signal dispatch.
b) Allow more accurate stack backtraces, since we have the
magic cookie, we can detect trap frames accurately.
c) The UTRACE guys want to be able to detect if a thread
off the cpu is in a system call, they can do that trivially
now just like they can on x86.
In fact much of this idea is from Roland McGrath.
3) Two cleanups from Adrian Bunk that are possible as a result
of the SunOS/Solaris support removal.
Please pull, thanks a lot!
