977 6821 d 10 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6821 d 13 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
832 6853 d 1 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6853 d 8 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 6854 d 7 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 6856 d 14 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
765 6861 d 2 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
760 6861 d 11 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.		  
534 6921 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6921 d 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6933 d 9 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
391 6982 d 2 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.		  
349 7001 d 3 h jermar /SPARTAN/trunk/ Optimize sorting functions so that malloc() and free() is called only for e_size > EBUFSIZE.
Smaller buffers are allocated directly on the stack.

Some copyright holder fixes on some files written by Ondrej Palkovsky.		  
289 7012 d 4 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.		  
251 7013 d 23 h palkovsky /SPARTAN/trunk/ Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first.		  
226 7015 d 9 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
194 7017 d 6 h palkovsky /SPARTAN/trunk/arch/amd64/ Code cleanup.  
188 7017 d 9 h palkovsky /SPARTAN/trunk/arch/amd64/ AMD64 now can switch into long mode.
Basic page tables working.		  
172 7023 d 11 h palkovsky /SPARTAN/trunk/arch/amd64/ Do not allow red area on stack in kernel mode.
Small updates for AMD64 memory layout.		  
169 7027 d 1 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().
