CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().

Fix bug in switch to userspace on ia64: ensure start in bank 1.
Fix bug in tlb_invalidate_all() that cause interrupts to be unconditionally enabled.
Optimize context switching by discarding packed attribute of context structures.

Userspace is now working.
There is an unrelated show stopper, however.

ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.
There is actually no appropriate syscall handler yet.

- Another item had to be allocated on stack to remember new value written to ar.bspstore.
Fix heavyweight interruption handler to calculate RSC.loadrs from the new value of ar.bspstore
instead from the old one.
Uncomment instructions switching ar.bspstore.
- Configure kernel with 512M of memory.

ivt.S:
Detect userspace stack in heavyweight handler and switch to kernel stack.
Remember the old stack pointer.
As for register stack, kernel stack is assumed still.
Fix alignment issues that showed when STACK_ITEMS was odd.
Fix ld8 instruction that did subtraction of 8 instead of addition of 8.
scheduler.c:
Change before_thread_runs_arch() to calculate address of top of the stack
for the interrupt handler.

/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.)

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.
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.
