917c2ccf3a Refactor stack pointers 
Change all linux/*/arch_regs.c to provide either ARCH_SP_REG
or ARCH_SP_PEEK_ADDR.  Introduce get_stack_pointer(), rewrite
all code accessing stack pointers to use get_stack_pointer().
On some architectures stack pointers were referred to as frame pointers,
clean up this confusion.

20ac169d7b Change the first argument of upeek from pid to tcp 
All users were changed automatically by:

	for i in `git grep -l 'upeek(tcp->pid'`; do \
		sed -i 's/upeek(tcp->pid/upeek(tcp/g' "$i"; \
	done

* upeek.c (upeek): Change the first argument from pid_t pid to struct
tcb *tcp. Use tcp->pid instead of pid in the function's body.

upeek calls.
