980 6810 d 16 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6810 d 17 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6810 d 19 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
840 6837 d 17 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
823 6844 d 7 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
822 6844 d 8 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.		  
814 6844 d 18 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
792 6846 d 16 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
789 6847 d 9 h palkovsky /kernel/trunk/generic/ Early SLAB initialization, the cpu-cache is initialized later.
If you want to use slab_cache_create befor slab_cpu_enable, add
a flag SLAB_CACHE_MAGDEFERRED.		  
788 6847 d 13 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
786 6847 d 15 h bondari /kernel/trunk/ frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed		  
778 6848 d 12 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
771 6849 d 7 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
762 6850 d 17 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
757 6851 d 10 h jermar /kernel/trunk/ Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64.		  
756 6852 d 7 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.		  
755 6853 d 6 h jermar /kernel/trunk/ Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.		  
754 6853 d 7 h jermar /kernel/trunk/generic/ Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas.		  
727 6864 d 8 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
718 6868 d 9 h decky /kernel/trunk/ interface change: as_area_load_mapping -> as_area_set_mapping (set single page mapping)
map init directly from the physical frames it is loaded in
