[PATCH 0/3] kinit: Allow mount options
This patch series allows user-specified mount commands to be
sent in via kernel command line ("kinit_mount=...") or via
an embedded /etc/fstab file.
The first patch is a cleanup of a patch sent last November
by San Mehat (http://web.archiveorange.com/archive/v/EazJNBMORV2U7E0coh5h);
the next two are small improvements or bug fixes.

[PATCH net-next 0/3] vhost: accelerate metadata access through vmap()
Hi:
This series tries to access virtqueue metadata through kernel virtual
address instead of copy_user() friends since they had too much
overheads like checks, spec barriers or even hardware feature
toggling.
Test shows about 24% improvement on TX PPS. It should benefit other
cases as well.
Please review

- Fixed maildir syncing: "UIDs not ordered in file" errors could have
occured sometimes wrongly
- --with-ioloop=epoll enables epoll code with Linux 2.6. Untested after
my changes.
- Pretty big changes in internal index handling code (I started this
change 2-3 months ago..)

Changes from V1:
- instead of pinning pages, use MMU notifier to invalidate vmaps and
remap duing
