3380 5745 d 22 h jermar /trunk/kernel/arch/amd64/include/ Prevent 'tmp' in amd64's atomic_lock_arch() from being allocated
to the same register as 'val->count'.		  
3233 5781 d 2 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3163 5821 d 20 h jermar /trunk/ First argument to atomic functions is read-write (amd64).  
3104 5832 d 10 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3070 5835 d 2 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types		  
3044 5835 d 21 h jermar /trunk/kernel/arch/amd64/ Some inline functions in memstr.h seem to be of uncertain origin (amd64).
Replace either with built-in functions or with generic functions.		  
3040 5836 d 5 h svoboda /trunk/kernel/arch/amd64/include/ Fix register-constraint typo in amd64 memstr.h and add two '&'s for symmetry's sake. (None were really causing trouble)  
2797 5895 d 21 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.		  
2794 5896 d 21 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2784 5910 d 20 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.		  
2777 5915 d 7 h cejka /trunk/ Unified context handling code for amd64.  
2774 5915 d 8 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.		  
2725 5953 d 3 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)		  
2721 5954 d 3 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2697 5975 d 4 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 5979 d 0 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2630 6024 d 19 h jermar /trunk/kernel/arch/ Formatting fixes.  
2612 6033 d 22 h jermar /trunk/kernel/arch/ Cleanup.  
2606 6035 d 1 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2467 6191 d 0 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
