416 6815 d 19 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Put RSE into lazy mode before writing ar.bspstore and ar.rnat.
Flush RSE before setting ar.bspstore so that ar.bsp is set to the same address.		  
414 6816 d 23 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.		  
413 6817 d 9 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.		  
412 6817 d 23 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
context_save() doesn't have to restore ar.pfs as it is a leaf procedure.
Get rid of assembler warning for start.S.		  
388 6831 d 20 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Map interrupt vectors to their names.		  
368 6843 d 19 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
322 6856 d 10 h jermar /SPARTAN/trunk/arch/ia64/ Reduce IA-64 context_t according to IA-64 ABI.

Make IA-64 port compile again.		  
309 6858 d 23 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
272 6861 d 15 h vana /SPARTAN/trunk/arch/ia64/ Symtab support for ia64  
266 6861 d 19 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
249 6862 d 14 h vana /SPARTAN/trunk/arch/ia64/src/ Serialization of psr write  
239 6863 d 15 h vana /SPARTAN/trunk/ Missing ";" added  
238 6863 d 15 h vana /SPARTAN/trunk/ Register dump on IA-64 exceptions  
230 6863 d 17 h cejka /SPARTAN/trunk/arch/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.		  
220 6864 d 1 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
212 6864 d 11 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
205 6864 d 23 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().		  
161 6880 d 21 h jermar /SPARTAN/trunk/arch/ For all relevant architectures, rename fake.s to dummy.s to better reflect the purpose of the file.
Also define global symbol called dummy.		  
120 6926 d 9 h jermar /SPARTAN/trunk/ 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.		  
106 6953 d 20 h jermar /SPARTAN/trunk/ 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.
