d0fddf5de8 (ia64_find_save_locs): Only call ia64_fetch_proc_info() when we really 
have to (i.e., if we don't have cached info).  Otherwise,

b3c1bf3f75 (flush_script_cache): Drop addr_space_t argument. Initialize 
hash-table, collision-chains, and hash-table in addition
	to clearing the script's IP value.  The latter wasn't nearly
	sufficient because it could cause loops on the collision
	chain...
(get_script_cache): Also lock the cache if global caching is in
	effect.  Take additional "saved_sigmaskp" argument.
	After flushing the cache, update the cache generation

a157d632f7 (desc_is_active): Need to cast 1 to (unw_word_t) before shifting it by

(access_reg) [HAVE_SYS_UC_ACCESS_H]: Sanitize and simplify this routine.  Turns out
