[PATCH] Fix si_band type in asm-generic/siginfo.h

From: Andi Kleen <ak@suse.de>

POSIX says si_band in siginfo_t must be long. glibc uses this, except
for Alpha.

This type must be correct on little endian machines, otherwise
Konqueror does not get any events from dnotity for created/deleted files.

Currenly asm-generic/siginfo.h uses int, which is wrong.

This patch adds a new macro __ARCH_SI_BAND_T which is int for alpha
and long for everybody else. This makes the type on x86-64 come out
correctly
