One more patch added:
http://review.whamcloud.com/#change,3745 add missing include dir

Three 3.5 support patches are also submitted for tracking purpose. I need them to start atomic_open change. They depend on Xuezhao's 3.4 patches so I didn't add any reviewer yet and I will rebase/resubmit later after Xuezhao's patches are merged.
http://review.whamcloud.com/#change,3755 v3.5 defines INVALID_UID
http://review.whamcloud.com/#change,3756 kernel 3.5 renames end_writeback to clear_inode
http://review.whamcloud.com/#change,3757 3.5 kernel encode_fh passes in parent inode

[Xuezhao Liu]

Add a new one:
http://review.whamcloud.com/3885 vfs: provides ll_get_acl to >i_op>get_acl

Rebased/resubmitted the un-merged patches for 3.4 kernel, addressed the comments for them and re-arranged the patches sequence to be same as kernel version.

[Peng Tao]

One more is added:
http://review.whamcloud.com/4039 llite:ll_inode_permission should check RCU walk

[Christopher Morrone]

Fix previous LU-1337 breakage of the build on ppc64:

Add one more patch to handle SEEK_HOLE/SEEK_DATA in ll_file_seek, which is introduced in 3.1 kernel.
