Hmm, I applied your first series of 5 patches (which I signed-off). When
trying to apply your second series, I get this from quilt:

Applying patch 2_1-Simplify-the-lifetime-logic-of-struct-uio_device.patch
patching file drivers/uio/uio.c
Hunk #2 succeeded at 287 (offset 8 lines).
Hunk #3 succeeded at 312 (offset 8 lines).
Hunk #4 FAILED at 339.
Hunk #5 succeeded at 806 (offset 17 lines).
Hunk #6 FAILED at 831.
Hunk #7 FAILED at 858.
Hunk #8 FAILED at 889.
4 out of 8 hunks FAILED -- rejects in file drivers/uio/uio.c
Patch 2_1-Simplify-the-lifetime-logic-of-struct-uio_device.patch does not apply (enforce with -f)

The first series applied without any fuzz against 2.6.36-rc5.

Thanks,
Hans
