1968 6411 d 22 h jermar /tags/ Canonize pre-0.2.0.3 tags: remove inner branches, tags and trunk directories.
The change now should reflect how those releases looked like after checkout.		  
1963 6411 d 23 h jermar /tags/0.1.1/ Tagging release 0.1.1  
1070 6636 d 10 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1063 6636 d 21 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
940 6641 d 1 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
802 6674 d 22 h palkovsky /kernel/trunk/arch/amd64/ Userspace now starts executing correctly.  
756 6680 d 20 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.		  
703 6699 d 7 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().		  
534 6739 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6739 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6751 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
391 6799 d 22 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 6818 d 23 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.		  
172 6841 d 8 h palkovsky /SPARTAN/trunk/arch/amd64/ Do not allow red area on stack in kernel mode.
Small updates for AMD64 memory layout.		  
164 6848 d 1 h palkovsky /SPARTAN/trunk/ Basics for amd64 architecture. It does compile, but it does not work yet.
