2.6.33 high cpu usage
With the ATI bug I was hitting earlier fixed, only my btrfs partition
continues to show high cpu usage for some operations.
Rsync, git pull, git checkout and svn up are typicall operations which
trigger the high cpu usage.
As an example, this perf report is from using git checkout to change to
a new branch; the change needed to checkout 208 files out of about 1600
total files. du(1) reports

[PATCH 0/2] Hyper-V synthetic interrupt controller
This patchset implements the KVM part of the synthetic interrupt
controller (synic) which is a building block of the Hyper-V
paravirtualized device bus (vmbus).
Synic is a lapic extension, which is controlled via MSRs and maintains
for each vCPU
- 16 synthetic interrupt "lines" (SINT's); each can be configured to
trigger a specific interrupt vector optionally with auto-EOI
