[ Upstream commit 565138ac5f8a5330669a20e5f94759764e9165ec ]

These flags are supposed to be bit numbers.  Right now they cause a double
shift bug where we use BIT(BIT(2)) instead of BIT(2).  Fortunately, the bit
numbers are small and it's done consistently so it does not cause an issue
at run time.
