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.
754

/kernel/trunk/generic/
Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas.
753

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

/kernel/trunk/generic/include/
Replace % operator by explicit overflow test to make this ADT compile on ia64.

/kernel/trunk/arch/ia64/
Fix initialization of pta.base on ia64.

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.
746

/kernel/trunk/test/mm/
Fix and cleanup frame allocator tests.
falloc1:
- fix so that it compiles on ia64
- check that frames is not NULL
falloc2:
- threads cannot be passed argument in the way this test did
(otherwise some threads will use the same value for val)
- check that frames is not NULL
- free frames at the end of the test

Remove ia64 boot as it is not needed by the simulator.

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.

Unlock address space prior TLB shootdown in get_asid() to unify
the locking order among mips32, sparc64 and ia64.

in a clean way.

Cannot printf in frame_alloc, because on ia32/amd64 it
would print before ega_init and that stucks fs.
