SYSENTER/SYSCALL support . add cpufeature detection of both . use it for both ipc and kernelcall traps, using a register for call number . SYSENTER/SYSCALL does not save any context, therefore userland has to save it . to accomodate multiple kernel entry/exit types, the entry type is recorded in the process struct. hitherto all types were interrupt (soft int, exception, hard int); now SYSENTER/SYSCALL is new, with the difference that context is not fully restored from proc struct when running the process again. this can't be done as some information is missing. . complication: cases in which the kernel has to fully change process context (i.e. sigreturn). in that case the exit type is changed from SYSENTER/SYSEXIT to soft-int (i.e. iret) and context is fully restored from the proc struct. this does mean the PC and SP must change, as the sysenter/sysexit userland code will otherwise try to restore its own context. this is true in the sigreturn case. . override all usage by setting libc_ipc=1 2012-06-10 19:50:17 +02:00			`member P_KERN_TRAP_STYLE p_seg.p_kern_trap_style`
