Hi,
Following patch fix panic on i386 for drivers using such functions.
Those two functions take 64-bit variable(s) for their arguments.
On i386 that takes additional 32-bit variable per argument.
This is required so that windrv_wrap() can correctly wrap function that
miniport driver calls with stdcall convention.
Similar explanation is provided in subr_ndis.c for other functions.
On amd64 we do not use these numbers.
