Origin of this file: copied from linux/x86_64 dir, blended with the

freebsd x86 changes and checked against objdump of a
|
||||
x86_64/freebsdprog
|
||||
- jge directly behind the syscall to branch on non-error
|
||||
- rcx is used as scratch reg (fpc/Linux-x86_64 uses edx)
|
||||
- More 6 and 7 param dosyscall because of the __syscall problem
