2784 6030 d 11 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 6030 d 12 h jermar /trunk/kernel/arch/amd64/src/cpu/ Fix cstyle.  
2777 6034 d 22 h cejka /trunk/ Unified context handling code for amd64.  
2774 6035 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 6039 d 13 h jermar /trunk/kernel/arch/amd64/src/ Fix breakage in non-debug amd64 build.  
2745 6051 d 21 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 6072 d 18 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 6073 d 17 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2721 6073 d 19 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2713 6077 d 18 h decky /trunk/kernel/arch/amd64/src/boot/ remove fake tab  
2712 6077 d 19 h decky /trunk/kernel/ prettyprint output  
2703 6084 d 16 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 6084 d 21 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2697 6094 d 19 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 6098 d 15 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2630 6144 d 10 h jermar /trunk/kernel/arch/ Formatting fixes.  
2612 6153 d 13 h jermar /trunk/kernel/arch/ Cleanup.  
2606 6154 d 16 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2604 6155 d 16 h jermar /trunk/kernel/arch/amd64/src/ Fix register names in exception dump and cstyle.  
2467 6310 d 15 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
