24981bc5f9 Important bug-fix: dl_iterate_phdr() doesn't appear to be signal-safe. 
To compensate, mask signal-delivery while it's running.

b15a2bd5ef ia64: Based on patch by Todd L. Miller: extend semantics of 
UNW_DYN_ALIAS to alias a sub-region of the aliased
	region.  The degenerate case of an empty subregion can
	then be used to alias with a particular IP.

7e8488d45d Allow unw_get_proc_name() to be called from signal-handler (for 
cursors in the local address-space).
Clarify that unw_get_proc_info(), unw_get_proc_info_by_ip(),
unw_init_remote(), unw_resume(), and unw_step() are async-signal
safe only from the local address-space (we can't make any guarantees
beyond that because of the dependency of the per-address-space
callback routines, which may have all kinds of restrictions).

77f159fe41 linux: Reimplement maps_init()/maps_next()/maps_close() such that 
they are async-signal safe.  This in turn also makes
	unw_get_proc_name() async-signal safe (for the local address
	space).

(KB): New macro.

(gettime): Fix typo and lower the assumed cache-line size from 64
	to 8 bytes just to be safe across platforms.
(measure_init): Lower N from 1000 to 100.
	(cursor): Add some padding between each unw_cursor_t to avoid
		benefitting from cache-line sharing.
	(uc): Likewise.
	Warm up the TLB before measuring the cold-cache cases.
(main): Unlimit the max. stack-size just in case.
	Write to "big" to ensure it's backed by real memory
	(not just by the zero page).
