[PATCH V2 1/2] cpufreq, xenpm: fix cpufreq and xenpm mismatch
Currently cpufreq and xenpm are out of sync. Fix cpufreq reporting of
if turbo mode is enabled or not. Fix xenpm to not decode for tristate,
but a boolean.

[patch 0/6] i386 gdt and percpu cleanups
Hi Andi,
This is a series of patches based on your latest queue (as of the
other day, at least).
It includes:
- the most recent patch to compute the appropriate amount of percpu
space to allocate, using a separate reservation for modules where
needed.
- make the percpu sections page-aligned, so that percpu variables can
be page aligned if needed (which is used by gdt_page)

[PATCH]Add free memory size of every NUMA node in phsical info
Returns free memory size per node in "xm info". This info can help users
who want to bind their guest domain in one node of their NUMA machines
thought set CPU affinity. I also write IA64 part support which I would
send to XEN-IA64 mail-list. Thanks.

Per-cpu patches on top of PDA stuff...
Hi Jeremy, all,
Sorry this took so long, spent last week in Japan at OSDL conf then
netconf. After several false starts, I ended up with a very simple
implementation, which clashes significantly with your work since then
8(. I've pushed the patches anyway, but it's going to be significant
work for me to re-merge them, so I wanted your feedback first.
The first patch simply changes
