configurable replacement for slab allocator
This adds a CONFIG_SLAB option under CONFIG_EMBEDDED. When CONFIG_SLAB is
disabled, the kernel falls back to using the 'SLOB' allocator.
SLOB is a traditional K&R/UNIX allocator with a SLAB emulation layer,
similar to the original Linux kmalloc allocator that SLAB replaced. It's
signicantly smaller code and is more memory efficient. But like all
similar allocators, it scales poorly and suffers from fragmentation more
than SLAB, so it's only appropriate for small systems.
It's been tested extensively in the Linux-tiny tree. I've also
stress-tested it with make -j 8 compiles on a 3G SMP+PREEMPT box (not
recommended).
Here's a comparison for otherwise identical builds, showing SLOB saving
nearly half a megabyte of RAM:
