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.

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.

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

mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.
Remove GET_PTL0_ADDRESS from kernel.
Update sparc64 comments in barrier.h.

sparc64 bugfix.
When disabling IMMU and DMMU the kernel has to perform synchronization operation
(e.g flush %r or membar #Sync instruction). There is no guarantee that the address
contained in %r is in DTLB and therefore the flush instruction can fault. Normally
this would be recognized and fixed by the OpenFirmware Fast Data MMU fault handler.
However, this handler lives in virtually mapped memory and an attempt to execute
there while the MMUs are disabled would result in a nested trap leading to error state.
Replacing flush %r instruction with membar #Sync, wich is sufficient in this case,
fixes this problem.

Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64.

Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.

Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.

Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.

Fix initialization of pta.base on ia64.

ia32 SMP updates.
Update info about supported version of Bochs (bump the counter to 2.2.6).
Add Task Priority Register type and initialize this register to a known state.

ia64 virtual address translation subsystem update.

ia64 work.
Add nice wrappers for thash and ttag instructions.
Add nice wrappers for accessing reion registers and PTA.
Fix set_vhpt_environment().
Allocate and initialize page_ht (a.k.a. VHPT).
Add missing header to sparc64.
Remove excessive header from debug.h.

sparc64 work.
13 bits wide means the max value is 8191 and not 0x8191.

sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.
