Begin MIPS implementation of 4-level page table interface.
Add email address to each item in doc/AUTHORS.
Correct type names in comments in mm/vm.c.
Introduce ptl0 pointer in vm_t.

Generic 4-level page tables interface & implementation (review & test).
Implement more architecture dependant macros on IA-32.
Provide fake implementation on IA-64 and MIPS.
Convert map_page_to_frame() to use the new interface.
Move adjusted map_page_to_frame() from IA-32's arch/mm/page.c to the generic mm/page.c.
119

Start with generic 4-level page table interface.
Usual cleanup.
117

Do panic() on page_fault().
Good for long testing in SMP mode as silent "extinctions" of a CPU are no longer supported.
Tiny changes here and there.
116

Add map_structure() to automate mapping of memory structures that can span multiple pages and/or cross page boundaries.
Change ACPI map_sdt() to use map_structure().
Small changes in MPS code.
The extra frame allocation for accessing frame 0 is unnecessary as it is possible to access frame 0 from kernel address space.
Zero TSS descriptor in the newly prepared GDT.
115

Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file.
Gain both better speed and size.
113

SMP recovery patch #2 (SMP is no longer broken !!!).
Fix missing KA2PA() operation in ap.S which was causing page faults during AP early initialization.
Fix bug in map_page_to_frame(): 'root' was interpretted as kernel address while read_dba() returns physical address.
Make references to page directory and page tables use kernel addresses instead of physical addresses.
Massive frame allocation code cleanup.
Basically revert to what we had had before implementation of userspace.
Usual cosmetics.
112

Define two placeholder functions for atomic_inc and atomic_dec on IA-64.
Add Ondrej Palkovsky to doc/AUTHORS.
Tweaks in IA-32 low level code to bring SMP back to life. (SMP still broken)
111
6964 d 22 h
palkovsky
/SPARTAN/trunk/
Code cleanup in scheduler.c thread.c - removed unnecessary spinlock.
atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h,
advisable to use even in non-smp mode.
Fixed atomic_inc, atomic_dec in mips architecture.

SMP recovery patch #1. (SMP still broken)
Move ap_boot() to K_TEXT_START_2 section.
Change ap_boot() to cope with mapping of kernel address space.
Change some addresses in mps.c from kernel to physical.
MIPS.
Move msim dprinter device to 0xB0000000.
This address is from kseg1 (unmapped, uncached) segment.
109

Discard 'copy' parameter of map_page_to_frame().
Introduce 'root' parameter of map_page_to_frame().
If 'root' is zero, page directory address is read from CPU.
Otherwise 'root' is used as page directory address.
Add missing word to new doxygen-style comments in scheduler.c.
106

IA-32 fixes.
Use kernel addresses instead of physical addresses in map_page_to_frame().
Physical addresses are supposed to only be exported to mm hardware.
Because of this fix, userspace is functional again.
Remap EGA videoram to (0x80000000 + videoram) and change the ega driver to work with the new address.
Minor cosmetics through out the code.
Changes in linker scripts.
