sys/amd64/include frame.h ucontext.h
Log:
For the page fault handler, save %cr2 in the outer trap handler so that
we do not have to run so long with interrupts disabled. This involved
creating tf_addr in the trapframe. Reorganize the trap stubs so that
they consistently reserve the stack space and initialize any missing
bits.
