[PATCH] add and use COMPAT_SIGEV_PAD_SIZE
All the 32 bit architectures (effectively) define SIGEV_PAD_SIZE to be
((SIGEV_MAX_SIZE/sizeof(int)) - 3). So define COMPAT_SIGEV_PAD_SIZE to be
this and replace SIGEV_PAD_SIZE32 where it is used. It also needs to be
used in the definition of struct compat_sigevent as most of the
architectures would have had it 4 bytes too small in the kernel (since we
were using SIGEV_PAD_SIZE).
