[PATCH 00/17] Extirpate IRQF_SAMPLE_REMOVE from the kernel

[Theodore Ts'o]

This set of changes is fairly straight forward; if there are no
objections, I plan to carry these in the random.git tree for the next
merge window.

[PATCH 14/17] [ARM] pxa: remove IRQF_SAMPLE_RANDOM which is now a no-op

[Theodore Ts'o]

With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a
no-op; interrupt randomness is now collected unconditionally in a very
low-overhead fashion; see commit 775f4b297b.  The IRQF_SAMPLE_RANDOM
flag was scheduled to be removed in 2009 on the
feature-removal-schedule, so this patch is preparation for the final
removal of this flag.

My original plan was to carry the patch in the random.git tree, so
that it only gets applied after the new random interrupt sampling
commit has gone in.  If you carry it in your tree, then the
/dev/random seeding for your platform will be worse until the
random.git tree is merged in.....
