2013-02-05mman: rename MAP_UNINITIALIZE to MAP_UNINITIALIZEDBernhard Reutner-Fischer
The name was changed to include a trailing 'D' when it went into the kernel. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2009-11-23nommu: use MAP_UNINITIALIZE for mallocsMike Frysinger
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>

sed -i -e '/Experimentally off - /d' $(grep -rl "Experimentally off - " *) sed -i -e '/^\/\*[[:space:]]*libc_hidden_proto(/d' $(grep -rl "libc_hidden_proto" *) should be a nop Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

things, and avoid potential deadlocks caused when a thread holding a uClibc internal lock get canceled and terminates without releasing the lock. This change also provides a single place, bits/uClibc_mutex.h, for thread libraries to modify to change all instances of internal locking.

this was sent earlier in a different form: http://www.uclibc.org/lists/uclibc/2004-January/008136.html find attached a smaller version ... perhaps adding a fprintf to stderr before calling abort would be nice like in the glibc patch, but whatever glibc has since adopted a similar fix for their malloc (third hunk, line 1970) http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/malloc/malloc.c.diff?r1=1.121&r2=1.122&cvsroot=glibc&f=h -mike
2004-07-15_SC_PAGESIZE is standard. Some ancient legacy unix variants used _SC_PAGE_SIZEEric Andersen
instead, but we are not such a system and should not propagate such things.
2004-07-15Use MAP_PRIVATE whenever __ARCH_HAS_MMU__ is set.Eric Andersen
Only use MAP_SHARED when mmu-less.
2003-12-30Rework malloc. The new default implementation is based on dlmalloc from DougEric Andersen
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
