There were some concerns that the earlier munmap patch could lead
to address space being freed that cannot be allocated again
by ggc due to fragmentation. This patch adds a fragmentation
fallback to solve this: when a GGC_QUIRE_SIZE sized allocation fails,
try again with a page sized allocation.

Passes bootstrap and testing on x86_64-linux with the fallback
forced artificially.

v2: fix missed initialization bug added in last minute edit.

	* ggc-page (alloc_anon): Add check argument.
	(alloc_page): Add fallback to 1 page allocation.
	Adjust alloc_anon calls to new argument.

From-SVN: r180649

This implements the freeing back of large chunks in the ggc madvise path
Richard Guenther asked for.  This way on systems with limited
address space malloc() and other allocators still have
a chance to get back at some of the memory ggc freed. The
fragmented pages are still just given back, but the address space
stays allocated.

I tried freeing only aligned 2MB areas to optimize for 2MB huge
pages, but the hit rate was quite low, so I switched to 1MB+
unaligned areas.

v2: Hardcode free unit size instead of param

gcc/:
2011-10-18  Andi Kleen  <ak@linux.intel.com>

	* ggc-page (release_pages): First free large continuous
	chunks in the madvise path.

From-SVN: r180648

This one place in ggc forgot to round page_entry->bytes to the
next page boundary, which lead to all the heuristics in freeing to
check for continuous memory failing. Round here too, like all other
allocators already do. The memory consumed should be the same
for MMAP because the kernel would round anyways. It may slightly
increase memory usage when malloc groups are used.

This will also increase the hitrate on the free page list
slightly.
