| H A D | traps.h | 6271cfdf Tue Aug 30 19:27:57 CDT 2016 Andy Lutomirski <luto@kernel.org> x86/mm: Improve stack-overflow #PF handling
If we get a page fault indicating kernel stack overflow, invoke
handle_stack_overflow(). To prevent us from overflowing the stack
again while handling the overflow (because we are likely to have
very little stack space left), call handle_stack_overflow() on the
double-fault stack.
