There's various fixes here, ranging from some architecture updates (ia64, 
ARM, MIPS, SH, Sparc64) to KVM, networking and network drivers.

And random one-liners.

But probably more important, and likely much more visible to most people 
is the fixes for the fallout from the hrtimers and no-HZ changes, and some 
of the ACPI regressions.

Those timer changes ended up much more painful than anybody wished for, 
but big thanks to Thomas Gleixner for being on it like a weasel on a dead 
rat, and the regression list has kept shrinking.

So if you have reported a regression in the 2.6.21-rc series, please check 
2.6.21-rc5, and update your report as appropriate (whether fixed or "still 
problems with xyzzy").
