Subject2.5.61-mjb1 (scalability / NUMA patchset)
Yeah, yeah. I know Linus beat me to it ... I'm just "fashionably late".


The patchset contains mainly scalability and NUMA stuff, and anything
else that stops things from irritating me. It's meant to be pretty stable,
not so much a testing ground for new stuff.

I'd be very interested in feedback from anyone willing to test on any
platform, however large or small.


Since 2.5.59-mjb5 (~ = changed, + = added, - = dropped)

Notes: Just a merge from 59-mjb6 up with 2.5.61 really ... I'd like
kprobes and lkcd tested though, if someone can.

Merged with Linus:
- summit_smp John Stultz
- cyclone_fixes John Stultz
- enable_cyclone John Stultz
- lost_tick John Stultz
- frlock_xtime Stephen Hemminger et al.
- frlock-xtime-i386 Stephen Hemminger et al.
- frlock-xtime-ia64 Stephen Hemminger et al.
- frlock-xtime-other Stephen Hemminger et al.
- numaq_ioapicids William Lee Irwin
- oprofile_p4 John Levon
- starfire Ion Badulescu
- tcp_fix Alexey
- pgd_ctor William Lee Irwin
- pfn_to_nid William Lee Irwin
- oprofile_fixes John Levon
- alt_sysrq_t Russell King
