1.7	24-Apr-2025	riastradh	mips longjmp: Use _UC_SIGMASK to restore signal mask. This way, restoring the signal mask and restoring the stack pointer happen atomically with respect to signal handler calls, whereas using sigprocmask would restore the signal mask _before_ the stack pointer, breaking sigaltstack. The motivation for using sigprocmask first and then setcontext later, rather than _UC_SIGMASK in setcontext, was to get SA-based libpthead sigprocmask interposition. But that's long gone and unlikely to come back. PR lib/57946: longjmp fails to restore stack first before restoring signal mask on most architectures
