David S. Miller 05c5e7698b sparc64: Fix race in signal instruction flushing. ... If another cpu does a very wide munmap() on the signal frame area, it can tear down the page table hierarchy from underneath us. Borrow an idea from the 64-bit fault path's get_user_insn(), and disable cross call interrupts during the page table traversal to lock them in place while we operate.
