* malloc-simple: Make calloc() return zeroed memorySteven J. Magnani2010-07-271-5/+4
| | | | | | | | | | The 0.9.31 release included a change to malloc-simple to request uninitialized memory from noMMU kernels. Unfortunately, the corresponding calloc() code assumed that memory returned by malloc() was already zeroed, which leads to all kinds of nastiness. Signed-off-by: Steven J.

* 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>
