-Subject: [PATCH gnumach 09/10] 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'.

-Subject: [PATCH gnumach 10/10] kern: remove the list of free stacks
-
-* kern/counters.c: Remove relevant counters.
-* kern/counters.h: Likewise.
-* kern/thread.c (stack_free_{list,count,limit}): Drop variables.
-(stack_next): Remove macro.
-(stack_alloc_try): Allocate stack using the slab allocator.
-(stack_alloc): Merely call `stack_alloc_try'.
-(stack_free): Adopt accordingly.
