4605 5658 d 0 h decky /branches/snapshot/ add task snapshoting branch  
4490 5686 d 18 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
3973 5783 d 2 h decky /trunk/kernel/ kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone()		  
3971 5784 d 15 h vana /trunk/kernel/arch/ia64/src/mm/ Fix I/O access to identicaly mapped space  
3940 5789 d 20 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3908 5793 d 19 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory

More capable TLB miss handlers.
The ia64 kernel now passes mm/mapping1 test.

Fix generic hash table to properly initialize lists.
