778 6669 d 5 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
776 6669 d 9 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.		  
775 6669 d 10 h palkovsky /kernel/trunk/generic/ 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.		  
773 6669 d 22 h palkovsky /kernel/trunk/ 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.		  
772 6669 d 23 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
771 6670 d 1 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
769 6670 d 22 h palkovsky /kernel/trunk/ 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.		  
768 6671 d 0 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6671 d 1 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6671 d 2 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
765 6671 d 3 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
764 6671 d 8 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
763 6671 d 9 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
762 6671 d 10 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6671 d 22 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.
