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

Page hash table modifications.

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.

Unlock address space prior TLB shootdown in get_asid() to unify
the locking order among mips32, sparc64 and ia64.
Add ASID_STEALING_ENABLED macro to disable the stealing part on ia64
in a clean way.
727
6819 d 22 h

/kernel/trunk/
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.

Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().

Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.

Cleanup.

Add functions to read and write TICK and TICK_compare registers.
Add types describing TICK and TICK_compare registers.

Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error.
sparc64 work.
Reorganize kernel vs. userspace memory layout.
Add panic_printf().
Turn dummy() into nop rather than into infinite loop.

sparc64 work.
Functions for disabling/enabling MMU.
TLB initialization.
Identity mapping of first 4M for kernel.
Switch to kernel copy of trap table.

/kernel/trunk/arch/sparc64/
sparc64 work.
Support for TLB Demap operations.
Add tlb_invalidate(), tlb_invalidate_asid() and tlb_invalidate_page() (latter two are broken as they ignore asid).
613

More ITLB and DTLB controlling functions.
