-Subject: [PATCH gnumach 2/3] kern: allocate kernel stacks using the slab
- allocator
-
-* kern/slab.c (kmem_cache_init): Relax alignment restriction.
-* kern/thread.c (stack_cache): New variable.
-(stack_alloc): Use the slab allocator.
-(stack_collect): Adjust accordingly.
-(thread_init): Initialize `stack_cache'.
