92b48f5fe8 (sos_alloc): cmpxchg_ptr() now returns a boolean value (TRUE on success).

ffb9c88e0a (ia64_find_save_locs): Separate out the no-cache case so we don't 
acquire the script-cache lock needlessly.

22ca263109 (ia64_init): To prevent a race, unw.needs_initialization must be cleared 
_after_ everything is initialized.

8b3248c32e (unw_set_caching_policy): If caching-policy didn't change, return 
early.  Always flush cache after changing the policy.
	This is to ensure that the per-thread cache gets initialized
	and no stale info remains.

caching.

	per-thread caching.

8d7426fe0a (linux_scratch_loc): Add a default-case which simply returns the 
register-location.  This is so that special-cases such

e5cf56ec1c (mi_init): Initializing unwi_full_sigmask is too late here, it needs to be done in the 
arch-specific initialization, so that thread-safety can be guaranteed.

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).

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.

d0fddf5de8 (ia64_find_save_locs): Only call ia64_fetch_proc_info() when we really

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
	here.
(put_script_cache): New function.
(ia64_get_cached_proc_info): Adjust for get_script_cache() and
	put_script_cache() changes.

	opening-coding the equivalent code.
