* malloc: simplify MAP_UNINITIALIZE ifdef logicMike Frysinger2010-07-271-7/+4

* nommu: use MAP_UNINITIALIZE for mallocsMike Frysinger2009-11-231-1/+1
| | | | | | | | | Now that the kernel supports MAP_UNINITIALIZE, have the malloc places use it to get real uninitialized memory on no-mmu systems. This avoids a lot of normally useless overhead involved in zeroing out all of the memory (sometimes multiple times). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Lea. It is about 2x faster than the old malloc-930716, and behave itself much better -- it will properly release memory back to the system, and it uses a combination of brk() for small allocations and mmap() for larger allocations. -Erik
