[PATCH 00/41] signal: Use set_current_blocked()

[Matt Fleming <matt@console-pimps.org>]

From: Matt Fleming <matt.fleming@intel.com>

Hi Oleg,

I did a tree wide scan of all the code that modifies current->blocked
without using the set_current_blocked() accessor. This patch series is
the result of the conversion to the new accessor functions.

This series also helps to reduce the complexity of my signal
scalability patches that I posted in April, because we now have much
fewer callers of recalc_sigpending() (the signal scalability patches
introduce a new lock that needs to be held when calling
recalc_sigpending()).

This series is available in the 'oleg/set-current-blocked' branch at,

    git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/linux-2.6.git

P.S I've punted on fully converting ia64 to set_current_blocked()
because bits of the signal code are written in asm. I'll follow up
with a later patch that does the conversion once I've improved my ia64
foo (or coerced Tony Luck into doing it ;).
