signal: Remove the need for __ARCH_SI_PREABLE_SIZE and SI_PAD_SIZE
Rework the defintion of struct siginfo so that the array padding struct siginfo to SI_MAX_SIZE can be placed in a union along side of the rest of the struct siginfo members. The result is that we no longer need the __ARCH_SI_PREAMBLE_SIZE or SI_PAD_SIZE definitions. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
