2784 5907 d 12 h jermar /trunk/kernel/arch/ Fortify ia32 and amd64 kernels against mallicious uspace applications that set
DF prior to entering the kernel. For AMD64 syscalls, we don't use the CLD
instruction, but make use of the SFMASK MSR instead. Simics works fine with
it, but QEMU seems to have a problem.		  
2783 5907 d 13 h jermar /trunk/kernel/arch/amd64/src/cpu/ Fix cstyle.  
2777 5911 d 23 h cejka /trunk/ Unified context handling code for amd64.  
2774 5912 d 0 h cejka /trunk/kernel/arch/ Context.s renamed to context.S for ia32 and fixed links for ia32xen.
Added asm macros for context save/restore and offset definitions.		  
2767 5916 d 14 h jermar /trunk/kernel/arch/amd64/src/ Fix breakage in non-debug amd64 build.  
2745 5928 d 22 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 5949 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 5950 d 17 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2721 5950 d 19 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2713 5954 d 19 h decky /trunk/kernel/arch/amd64/src/boot/ remove fake tab  
2712 5954 d 19 h decky /trunk/kernel/ prettyprint output  
2703 5961 d 17 h jermar /trunk/kernel/arch/amd64/ Grow the initial identity mapping from 64M to 4G.
We should not allocate GDT's from above 4G or the amd64 will occassionally
triple-fault again.		  
2701 5961 d 21 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2697 5971 d 20 h decky /trunk/kernel/ amd64: shorten kernel address space by 2 GB to support proper mapping of more than 2 GB of physical memory  
2692 5975 d 16 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2630 6021 d 11 h jermar /trunk/kernel/arch/ Formatting fixes.  
2612 6030 d 14 h jermar /trunk/kernel/arch/ Cleanup.  
2606 6031 d 17 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2604 6032 d 17 h jermar /trunk/kernel/arch/amd64/src/ Fix register names in exception dump and cstyle.  
2467 6187 d 16 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
