[PATCH v7 00/12] Support non-lru page migration
Recently, I got many reports about perfermance degradation in embedded
system(Android mobile phone, webOS TV and so on) and easy fork fail.
The problem was fragmentation caused by zram and GPU driver mainly.
With memory pressure, their pages were spread out all of pageblock and
it cannot be migrated with current compaction algorithm which supports
only LRU pages. In the end, compaction cannot

Dmesg log for 2.6.31-rc8 kernel been built on F12 (rawhide) vs log for same kernel been built on F11 and installed on F12
Previous 2.6.31-rc8 kernel was built on F11 and installed with modules on F12.
Current kernel has been built on F12 (2.6.31-0.204.rc9.fc12.x86_64) and installed
on F12 before loading under Xen 3.4.1.
Dmesg log looks similar to Michael Yuong''s ''rc7.git4'' kernel for F12.

Greetings,
after Carsten pitched CMM2 on the kvm mini summit here is a repost
of version 5 of the guest page hinting patches. The code is still

[patch 0/6] [rfc] guest page hinting version 5
After way to many months here is the fifth version of the guest page
hinting patches. Compared to version four a few improvements have been
added:
- Avoid page_host_discards() calls outside of page-states.h
- The discard list is now implemented via the page_free_discarded
hook and architecture specific code.
- PG_state_change page flag has been replaced with architecture

[PATCH] drm/nouveau/fbcon: fix deadlock with FBIOPUT_CON2FBMAP
The FBIOPUT_CON2FBMAP ioctl takes a console_lock(). When this is called
while nouveau was runtime suspended, a deadlock would occur due to
nouveau_fbcon_set_suspend also trying to obtain console_lock().
Fix this by delaying the drm_fb_helper_set_suspend call. Based on the
i915 code (which was done for performance reasons though).
