1780 6748 d 12 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6769 d 14 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1511 6780 d 14 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1423 6786 d 15 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6789 d 12 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 6857 d 19 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1064 6858 d 4 h palkovsky /kernel/trunk/arch/amd64/ Cleanup of amd64 code.  
1063 6858 d 5 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
977 6860 d 15 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6860 d 18 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
940 6862 d 10 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
832 6892 d 6 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6892 d 13 h jermar /kernel/trunk/ Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared).		  
825 6893 d 12 h jermar /kernel/trunk/ Remove WAKEUP_IPI stuff.

Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.		  
808 6895 d 19 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
802 6896 d 6 h palkovsky /kernel/trunk/arch/amd64/ Userspace now starts executing correctly.  
765 6900 d 8 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6900 d 14 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6900 d 16 h jermar /kernel/trunk/ mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.

Remove GET_PTL0_ADDRESS from kernel.

Update sparc64 comments in barrier.h.		  
756 6902 d 5 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
