Add PAGE_WIDTH to aid divisions by PAGE_SIZE.

Tested basic non-cached slab allocation.

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.

/kernel/trunk/
Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727
6775 d 17 h
jermar
/kernel/trunk/
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
704
6781 d 23 h
jermar
/kernel/trunk/
Make various mips32 tlb manipulation functions preserve EntryHi register.
Cleanup and more precise comments for previous commit.

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.
Pass address space identifier to functions in page_operations to support single global page hash table.

/kernel/trunk/arch/mips32/src/mm/
Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.

/kernel/trunk/arch/mips32/src/mm/
Weaken the assumption, that PageMask register contains the right mask everytime.
As a result, TLB exceptions will explicitly write this register when filling TLB entry.
Adjust tlb_print() on mips32 to print PageMask as well.
599

/kernel/trunk/arch/mips32/
Fixes for mips32 invalidation functions.

jermar
/kernel/trunk/arch/mips32/src/mm/
TLB invalidation functions for mips32. Not deployed yet. Not tested.
594

ptlb command (currently usable on mips32 only).
569
6817 d 17 h

sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.

Rename HelenOS/SPARTAN to HelenOS/kernel again.

Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.

6834 d 17 h
jermar
/SPARTAN/trunk/
Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.
413
6869 d 16 h
jermar
/SPARTAN/trunk/
Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.
