1861 6467 d 7 h jermar /trunk/kernel/arch/sparc64/ Convert sparc64 traps using SIMPLE_HANDLER to using PREEMPTIBLE_HANDLER.  
1860 6468 d 1 h jermar /trunk/kernel/ A lot of untested sparc64 stuff:
- Write ASID to hardware when a thread is about to run in userspace.
- Add userspace() and switch_to_userspace() functions.
- Handle special cases when the userspace spill/fill handler causes MMU trap.
- Resolve some TODOs in the existing sparc64 code.
- sparc64 has now C99 compliant header guards.
- Formatting and indentation fixes.		  
1859 6468 d 8 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
- Convert interrupt_vector trap handler and some mm related trap handlers to
use preemptibe_handler(), which is essential for traps coming from userspace.
- Add fast_data_access_protection() handler.		  
1852 6473 d 1 h jermar /trunk/kernel/ sparc64 work.
Bunch of changes in preparation for sparc64 mm and userspace support.
Fix alignment of hardcoded_* variables in linker script.		  
1851 6478 d 7 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.		  
1849 6482 d 8 h jermar /trunk/kernel/ sparc64 work.
interrupt_vector trap experimental handling.
Minimal reverse-engineered FireHose Controller driver (documentation needed!).

667 6713 d 1 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Rename saving_handler() to preemptible_handler()
and fix it to make sparc64 kernel preemptive.
Add two handlers for two fatal exceptions (i.e.
instruction_access_exception and mem_address_not_aligned.
Fix panic_printf() to not allocate its own register window.		  
666 6714 d 22 h jermar /kernel/trunk/ sparc64 work.
