fvdl	01fbe9c413	Drink the swapgs kool-aid. Enable the use of syscall/sysret as the default system cal entry point.	2002-06-03 18:23:16 +00:00
fvdl	8b277a3d68	Add definition for CPU-private data (in a remapped page in the data segment). Somewhat of a kludge to be able to switch stack pointers in in the syscall entry point without clobering a register, avoiding the terror of 'swapgs'.	2002-05-28 23:09:36 +00:00
fvdl	9b4c0e34d2	Initial commit of the port to AMD's upcoming 64 bit architecture, the x86-64. Since there's no hardware available yet, this port is only known to run on the Simics simulator for at the moment, and as such uses the PC devices that it simulates for now. It will be developed more (and cleaned up) as the hardware becomes available.	2001-06-19 00:19:12 +00:00
