ia64 CPU identification.

/SPARTAN/trunk/arch/ia64/src/
ia64 work.
Comment some offending steps of heavyweight interrupt handler regarding RSE switching.
With this change, ia64 will do well on tests rwlock #4 and thread #1.
Cleanup.

Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.
ia64 work.
Better General Exception handler.

ia64 work.
Big cleanup of IA-64 interrupt processing.
Merge of interrupt.c and interrupt_handler.c.
Rewrite of ivt.S and interrupt.c.
Higher level interrupt handlers are now passed a vector number and a pointer to stack structure.
ia32 work.
ia32 has ordered writes. Until it deploys weaker memory ordering model, write_barrier() can be empty statement.

ia64 work.
Do not break memory stack alignment in heavyweight interrupt handler.
Reserve scratch area for nested procedure calls on memory stack.

/SPARTAN/trunk/arch/ia64/src/
r12 (stack pointer) must be descremented prior to storing data into new memory stack frame.

/SPARTAN/trunk/arch/ia64/src/
Two small ia64 improvements.
438

ia64 work.
Heavyweight handler should be complete up to the point where it switches back to interrupted RSE context.
435
6860 d 22 h
jermar
/SPARTAN/trunk/arch/ia64/
ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.

ia64 work.
Fix definition of __u32.
Add more register manipulation functions.
Add unions describing bit-structured registers.
Distinguish between timer, unhandled and spurious external interrupts.
Initialize interval timer to generate first timer interrupt.

/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.

6879 d 9 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
6879 d 19 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.
