3672 5865 d 17 h jermar /trunk/ Merge sparc branch to trunk.  
2071 6553 d 16 h jermar /trunk/ (c) versus (C)  
2065 6567 d 14 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
1891 6674 d 14 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1860 6692 d 18 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.		  
1823 6722 d 21 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6723 d 1 h jermar /trunk/ sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.

This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.

Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow.		  
1787 6743 d 18 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6750 d 19 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6771 d 22 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
617 6953 d 14 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Support for TLB Demap operations.
Add tlb_invalidate(), tlb_invalidate_asid() and tlb_invalidate_page() (latter two are broken as they ignore asid).		  
534 6962 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6962 d 17 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
531 6963 d 16 h jermar /kernel/trunk/arch/sparc64/include/mm/ sparc64 work.
MMU ASI & virtual addresses definitions.		  
530 6964 d 2 h jermar /kernel/trunk/arch/sparc64/include/mm/ sparc64 work.
TTE (Translation Table Entry) type definitions.
