2089 6500 d 18 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6506 d 18 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6511 d 10 h jermar /trunk/ (c) versus (C)  
1903 6623 d 11 h jermar /trunk/ SMP stuff for sparc64.
Almost complete except for IPIs.
The absence of IPI support deadlocks

1902 6624 d 15 h jermar /trunk/kernel/arch/sparc64/include/ Implement spinlock and test_and_set for sparc64.  
1890 6632 d 19 h jermar /trunk/ - Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.

- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.

- More TSB work on the sparc64 front.		  
1888 6636 d 14 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1860 6650 d 12 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.		  
1787 6701 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6702 d 10 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.		  
1780 6708 d 14 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6729 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1104 6812 d 14 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1082 6817 d 11 h jermar /kernel/trunk/arch/sparc64/include/ Fix atomic_postdec() operation.  
1024 6819 d 12 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
863 6841 d 7 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add initial TLB miss handlers.		  
861 6841 d 18 h jermar /kernel/trunk/arch/sparc64/include/ Add atomic_add() operation for sparc64.
