Minor bugfix caused by invalid frame_region_not_free() usage

Rename HelenOS/SPARTAN to HelenOS/kernel again.

Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)

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

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.

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.

Small improvement in pte_t type definition.

mips32 memory management work.
TLB exceptions seem to be working on at least simics.
msim handles TLB Refill and TLB Invalid exceptions well,
but seems to skip writes to the mapped addressies in mm
mapping test #1 (the data is not written and exception
is not triggered).

Small changes to mips32 mm.
Small changes in mm mapping test #1.
396
6845 d 18 h

/SPARTAN/trunk/
Add mm/mapping1 test.
(Will not make it past TLB Invalid exception on mips32.)
Fixes in asid.c.
Make TLB register types union with __u32 value.
Implement tlb_invalidate() for mips32.
(TLB invalidation and shootdown path will have to be revised.)

Small fix.
MIPS32 pte_t.c is not bool.

MIPS32 memory management work.
Fix some bugs introduced yesterday (PTL3 index is indeed calculated by >> 14).
Introduce two new bits in pte_t (i.e. 'a' and 'w').
Implement TLB Invalid Exception and TLB Modified Exception. (Needs review and testing)

mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.
Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.

MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.
Other architectures: add dummy tlb_init_arch().

Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.

Updated symtab so that it works correctly with BE architectures.
Changed compiler for BE MIPS to be mips-sgi-irix5, because
mipsel -EB does not behave correctly.
Doc updates to amd64.
Added ARC BIOS support to MIPS architecture. Putchar works correctly,
kernel passed FPU & some rwlock tests.

Basic changes to boot it on SGI Indy.

6872 d 5 h

/SPARTAN/trunk/
Cleanup of makefiles to have common options in one main makefile.
Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.
There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.
