the real one.

1877ea16ca Fix obstack* on i?86
obstack calls several callbacks, so on i?86 it'd better be compiled
without -mpreferred-stack-boundary=2, otherwise the callbacks are called
with misaligned stack.

bec466d922 Fix race in corruption check.
With atomic fastbins the checks performed can race with concurrent
modifications of the arena.  If we detect a problem re-do the test
after getting the lock.

bea0ac1d87 Use rel semantics of cas instead of acq semantics with full barrier before it in _int_free
The following patch fixes catomic_compare_and_exchange_*_rel definitions
(which were never used and weren't correct) and uses
catomic_compare_and_exchange_val_rel in _int_free.  Comparing to the
pre-2009-07-02 --enable-experimental-malloc state the generated code should
be identical on all arches other than ppc/ppc64 and on ppc/ppc64 should use
lwsync instead of isync barrier.

	* malloc/arena.c (heap_info): Add mprotect_size field, adjust pad.
	(new_heap): Initialize mprotect_size.
	(grow_heap): When growing, only mprotect from mprotect_size till
	new_size if mprotect_size is smaller.  When shrinking, use PROT_NONE
	MMAP for __libc_enable_secure only, otherwise use MADV_DONTNEED.

	[BZ #4349]
	* malloc/malloc.c: Keep separate list for first blocks on the bin
	lists with a given size.  This helps skipping over list elements
	we know won't fit in two places.
	Inspired by a patch by Tomash Brechko <tomash.brechko@gmail.com>.
