mm: make stack guard page logic use vm_prev pointer
commit 0e8e50e20c837eeec8323bba7dcd25fe5479194c upstream. Like the mlock() change previously, this makes the stack guard check code use vma->vm_prev to see what the mapping below the current stack is, rather than have to look it up with find_vma(). Also, accept an abutting stack segment, since that happens naturally if you split the stack with mlock or mprotect.
