[GIT PULL] block bits for 2.6.36-rc3

[GIT PULL] block bits for 2.6.36-rc3

[Jens Axboe]

Hi Linus,

All of these (except a single fix) have been brewing while
you were away and have been in -next for over a week as well.
All are fixes for bugs, the cfq patches are the odd ones out.
But they have been well tested and should have been included
in the first merge in the merge window, so I don't have an
issue pushing them now.

Please pull.
