Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.

/kernel/trunk/generic/
Added more granular locking to slab allocator and thus fix
hopefully last race condition.

Added scheduler queues output. The scheduler is buggy - on SMP
the cpus never get tu cpu_sleep, in slab2 test on 4 cpus everything
is on the first cpu.
The slab allocator passes tests in this configuration, but in slightly
different(more efficient) locking order it panics. TODO: Find out why
does it panic.

Added slab stress test.
Fixed race condition in slab allocator.
Moved initialization of slab to the point where we know correct config.cpu_count
Correctly passes tests on amd64, ia32 in both bochs & qemu.

Implemented malloc/free as SLABs.

SLAB allocator now uses itself for all its internal structures.
Added description of allocator.
Removed messy_stack_trace from amd64, as it would scroll away important
part of exception.

Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.

Partially working SLAB CPU cache.

Basic SLAB (without CPU-cache) passes test.

Add PAGE_WIDTH to aid divisions by PAGE_SIZE.

Tested basic non-cached slab allocation.

Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
762

/kernel/trunk/
Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference

Skeleton of SLAB allocator.
