1: correct LDT checks 2: add address validity check to guest_map_l1e() 3: use {rd,wr}{fs,gs}base when available 4: check for canonical address before doing page walks Signed-off-by: Jan Beulich <jbeulich@suse.com>

All- With suggestions from Ian and previous posts on this list, I''ve been investigating why Xen causes a Transmeta-based system to reboot immediately.. I''ve added instrumentation to xen/arch/x86/boot/x86_32.S (a collection of ''.asciz "foo"'' statements) hoping to locate a point of failure.. and it dies sometime before this code is run.. At what point

This series consists of improvements to Xen''s ability to print traces of its own stack, and specifically for the stack overflow case to be able to use frame pointers in a debug build. I have dev tested the series in debug and non-debug cases, with and without memory guards, and I believe that all the stack traces look correct (given the available information Xen has), and that the
