[PATCH 0/7] Clean up signal code

[Franck Bui-Huu <vagabon.xyz@gmail.com>]

Hi,

This patchset cleans up signal related code by factorizing code
shared by all signal sources. The consequence is that the signal
code is decreased a lot.

This patchset has been splitted out into 7 differents patches
to ease code review.

Two questions are still open: 

    (a) It seems that the status register is not saved by
        setup_sigcontext() and therefore not restored by
        restore_sigcontext(). Is it a bug ?

    (b) Status register is saved by setup_sigcontext32() but
        not restored by restore_sigcontext(). Is it a bug ?

Unfortunately I do not have any 64 bits cross compiler setup
and no adequate plateforms to test the changes introduced by
this patchset in signal32.c and signal_n32.c. If someone
could give it a try, that would be nice.

Please, consider.

                Franck
