When int 0x80 is called from long mode r8-r11 would leak out of the kernel (or rather they would be filled with some values from the kernel stack). I don't think it's a security issue because the values come from the fixed stack frame which should be near always user registers from a previous interrupt. Still better fix it. Longer term the register save macros need to be cleaned up to avoid such mistakes in the future. Original analysis from Richard Brunner, fix by me.
