MIPS's siginfo handling has been broken since this commit:
commit 574c4866e3
Author: Al Viro <viro@zeniv.linux.org.uk>

consolidate kernel-side struct sigaction declarations
for 64-bit BE MIPS CPUs.
The UAPI variant looks like this:
struct sigaction {
unsigned int sa_flags;
__sighandler_t sa_handler;
sigset_t sa_mask;
};
but the core kernel's variant looks like this:
struct sigaction {
#ifndef __ARCH_HAS_ODD_SIGACTION
__sighandler_t sa_handler;
unsigned long sa_flags;
#else
unsigned long sa_flags;
__sighandler_t sa_handler;
#endif
#ifdef __ARCH_HAS_SA_RESTORER
__sigrestore_t sa_restorer;
#endif
sigset_t sa_mask;
};
The problem is that sa_flags has been changed from an unsigned int to an
unsigned long.
Fix this by making sa_flags unsigned int if __ARCH_HAS_ODD_SIGACTION is
defined.
Whilst we're at it, rename __ARCH_HAS_ODD_SIGACTION to
__ARCH_HAS_IRIX_SIGACTION.

The existing asm-generic versions are incomplete and included
by some architectures. New architectures should be able
to use a generic version, so rename the existing files and
change all users, which lets us add the new files.
