2467 6360 d 0 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2465 6365 d 3 h jermar /trunk/ Merge arm32 into trunk.  
2441 6372 d 20 h decky /trunk/kernel/ fix ICC compilation  
2089 6496 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6506 d 21 h jermar /trunk/ (c) versus (C)  
2007 6553 d 20 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.		  
1891 6627 d 20 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6628 d 6 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.		  
1889 6628 d 22 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support		  
1888 6632 d 1 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6696 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6704 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6725 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1511 6736 d 3 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1468 6738 d 1 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1423 6742 d 4 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6745 d 1 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1070 6813 d 8 h jermar /kernel/trunk/ More checks for address space area conflicts.  
977 6816 d 4 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6816 d 7 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.
