3973 5781 d 21 h decky /trunk/kernel/ kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone()		  
3908 5792 d 14 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3778 5835 d 19 h jermar /trunk/kernel/arch/ia64/include/mm/ Extern declaration for ia64 last_frame.  
2721 6169 d 19 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2071 6553 d 12 h jermar /trunk/ (c) versus (C)  
1888 6678 d 16 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6743 d 14 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 6771 d 18 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
967 6862 d 22 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
944 6864 d 12 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
935 6864 d 15 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
911 6871 d 16 h jermar /kernel/trunk/arch/ia64/ ia64 work.

Change heavyweight interrupt handler to use bank 0 registers instead of AR.KR0 and AR.KR1.
This prevents userspace from the possibility to see what addresses are being used by kernel.

Store kernel stack address in bank 0 r23 instead of AR.KR7. Again, userspace will not be
able to read the address of its kernel stack.

Increase FRAME_SIZE to 64K as this is the first supported page size in which will fit
thread's combined register and memory stack. (RSE can write out as many as 16K.)		  
763 6902 d 18 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
715 6920 d 15 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
534 6962 d 13 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6962 d 13 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6974 d 18 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
102 7152 d 13 h jermar /SPARTAN/trunk/ IA-64 work.
Redefine FRAME_SIZE to "(16*1024)" instead of "2*4096". Note that the latter definition was wrong because of the lack of "()".
Take panic_printf(), cpu_halt() and memsetb() out of fake.s and implement them properly in asm.S.
Move ski_init_console() from arch_post_mm_init() to arch_pre_mm_init().
In start.S, write r0 to ar.bspstore.

Janitorial fixes.
Add count_t type.
Replace several occurrences of int and __u32 by count_t or size_t.
Shorten several panic strings.		  
35 7179 d 22 h jermar /SPARTAN/trunk/ Early support for IA-64 architecture.
