Fix sparc64 and ia64 to work with the changed frame allocator.
Fix ppc32 to at least compile.

Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.
Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.

Fix number of steps in softint division.
Make ia64 port compile with softint.

Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.

Page hash table architectures now use generic hash table to manage
mappings.

frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed

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

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.
753

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

Fix initialization of pta.base on ia64.

ia64 virtual address translation subsystem update.
748

First HT_HASH_ARCH implementation for 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.

sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.
741
6760 d 14 h
jermar
/kernel/trunk/
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.
