Linus,
Please pull the for-linus branch from the git tree:

HEAD:7146db3317c67b517258cb5e1b08af387da0618b signal: Better detection of synchronous signals
This contains 4 small fixes for signal handling. A missing range check, a regression fix, prioritizing signals we have already started a signal group exit for, and better detection of synchronous signals.
The confused decision of which signals to handle failed spectacularly when a timer was pointed at SIGBUS and the stack overflowed. Resulting in an unkillable process in an infinite loop instead of a SIGSEGV and core dump.
Eric W. Biederman (4): signal: Make siginmask safe when passed a signal of 0 signal: Always attempt to allocate siginfo for SIGSTOP signal: Always notice exiting tasks signal: Better detection of synchronous signals
