2008-10-28Finally fix the MALLOC=y and MALLOC_SIMPLE=y breakage from svn 23660. (I ↵Rob Landley
found it, this is Bernhard's patch to fix it. Tested and it Works For Me (tm)).
2008-10-11Fix bug 4994 hangs on read(). I have tested the patch extensibly on ARM/LT.old.Khem Raj
Thank you Chase Douglas for reporting it and for the patch.

2002-07-25Redo the locking, so that it may actually work. Now locking is done atMiles Bader
the malloc/free level, not within the heap abstraction, and there's a separate lock to control sbrk access. Also, get rid of the separate `unmap_free_area' function in free.c, and just put the code in the `free' function directly, which saves a bunch of space (even compared to using an inline function) for some reason.
2002-07-19Rename mutex stuff to use heap-specific names.Miles Bader
Doc fix.
2002-07-18Miles Bader implemented a new mmap based malloc which is muchEric Andersen
smarter than the old "malloc-simple", and actually works, unlike the old "malloc". So kill the old "malloc-simple" and the old "malloc" and replace them with Miles' new malloc implementation. Update Config files to match. Thanks Miles!
