[PARISC] fix user-triggerable panic on parisc
int sys32_rt_sigprocmask(int how, compat_sigset_t __user *set, compat_sigset_t __user *oset,
unsigned int sigsetsize)
{
sigset_t old_set, new_set;
int ret;
if (set && get_sigset32(set, &new_set, sigsetsize))
...
static int
get_sigset32(compat_sigset_t __user *up, sigset_t *set, size_t sz)
{
compat_sigset_t s;
int r;
if (sz != sizeof *set) panic("put_sigset32()");
In other words, rt_sigprocmask(69, (void *)69, 69) done by 32bit process
will promptly panic the box.
