3973 5588 d 22 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()		  
3972 5589 d 10 h decky /trunk/kernel/ kernel memory management revisited (phase 1): proper support for zone flags
- the zone_t structures are now statically allocated to be easily available
- the locking scheme was simplified
- new flags for non-available zones were introduced
- FRAME_LOW_4_GiB flag is removed, the functionality will be eventually reimplemented using a generic mechanism		  
3940 5595 d 17 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3908 5599 d 15 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3891 5601 d 13 h jermar /trunk/ Get rid of CONFIG_SIMICS_FIX.  
3790 5638 d 22 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3240 5799 d 23 h decky / move unfinished ObjC support to a separate branch  
2725 5975 d 19 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)		  
2723 5976 d 18 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2721 5976 d 20 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2712 5980 d 20 h decky /trunk/kernel/ prettyprint output  
2702 5987 d 20 h decky /trunk/kernel/arch/ia32/src/mm/ change cstyle to human-readable form  
2701 5987 d 22 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2697 5997 d 21 h decky /trunk/kernel/ amd64: shorten kernel address space by 2 GB to support proper mapping of more than 2 GB of physical memory  
2441 6226 d 12 h decky /trunk/kernel/ fix ICC compilation  
2439 6226 d 13 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2222 6279 d 13 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust		  
2125 6335 d 14 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2106 6343 d 21 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.		  
2100 6348 d 15 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast
