[PATCH] add sysenter/syscall emulation for 32bit compat mode

2009-06-16 Thread Andre Przywara
sysenter/sysexit are not supported on AMD's 32bit compat mode, whereas syscall is not supported on Intel's 32bit compat mode. To allow cross vendor migration we emulate the missing instructions by setting up the processor state accordingly. The sysenter code was originally sketched by Amit Shah, it
