a) vfc is not 64bit-clean, marked as such in Kconfig
	b) aurora is simply broken - still uses tqueues.  Marked as broken.
	c) vfc does dereferencing of userland pointer, right after having
carefully copied the data to kernel space ;-)  Fixed.
	d) vfc ->mmap() had missed prototype change.  Fixed.
	e) BPP ioctls are misdeclared - they should've been _IO(...) instead
of _IOR(..., void).  Too late to fix, but we can at least make them
_IOR(..., char) - same value, but doesn't try to find sizeof(void).
