[PATCH] Fix sigevent_t stuff

[Ralf Baechle <ralf at linux-mips dot org>]

Uli,

below patch fixes a mismatch between glibc and the kernel header's
definition on MIPS.  Please apply.

Thanks,

  Ralf

2003-08-31  Ralf Baechle  <ralf@linux-mips.org>

	* sysdeps/unix/sysv/linux/mips/bits/siginfo.h: Delete comment
	obsoleted by this patch.
	(__SIGEV_PAD_SIZE: Change the definition such that it'll keep the size
	of sigevent_t at SIGEV_MAX_SIZE bytes for 64-bit also.
	(SIGEV_MAX_SIZE): Remove unused definition making this match the
	kernel definition.
