Looking through the various asm-*/siginfo.h files in Linux 2.3.41pre2,
I've encountered only two platforms with problems: Alpha and Sparc.
Could the maintainers of these platforms please check the following
and take appropriate action?

Alpha defines:
#define SI_PAD_SIZE     ((SI_MAX_SIZE/sizeof(int)) - 4)
#define SIGEV_PAD_SIZE  ((SIGEV_MAX_SIZE/sizeof(int)) - 4)

but all other platforms have a 3 instead of a 4 for these two defines:
#define SI_PAD_SIZE     ((SI_MAX_SIZE/sizeof(int)) - 3)
#define SIGEV_PAD_SIZE  ((SIGEV_MAX_SIZE/sizeof(int)) - 3)

Sparc and Sparc64 additionally define the member _trapno for _sigfault
- and SIGEMT is also only used by Sparc*:
                /* SIGILL, SIGFPE, SIGSEGV, SIGBUS, SIGEMT */
                struct {
                        void *_addr;    /* faulting insn/memory ref. */
                        int  _trapno;   /* TRAP # which caused the signal */
                } _sigfault;


Do we need Linux/alpha and Linux/sparc versions of <bits/siginfo.h>?
