8e71bb0ab2 (unw): Initialize "lock" member. Switch to ANSI99-style initializers. 
(ia64_init): Use unw.lock to protect against races during
	initialization.  Disable signal delivery during initialization
	to ensure thread-safety (e.g., unw_init_local() may call
	ia64_init() and the former must be thread-safe).

b85b2fb28f [PATCH] x86: fix unw_is_signal_frame() and unwinding across signal handlers 
This patch fixes two problems: first, it makes unwinding across signal
handlers work on x86 and second it fixes unw_is_signal_frame() to work
properly when SA_SIGINFO is in effect.

656e9d6e7d (_Uia64_search_unwind_table): Correct off-by-8 error in calculating 
personality-routine and LSDA address and dont' forget to
	dereference the personality-routine function-pointer, so we
	really get the address of the function-descriptor of the
	personality routine.
(callback): Set the segment-base based on the segment that contains
	the unwind-table.  Normally, that the text segment but in
	special cases, such as the kernel's gate DSO, it will be
	in a different segment.

most scratch register and caused test-setjmp to fail.
