Discussing with Matthew Wilcox some of his outstanding patches lead me to this patch (among others). The preamble in struct sigevent can be expressed independently of the architecture. Also use __ARCH_SI_PREAMBLE_SIZE on ia64. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
