// USER needs a way to distinguish between a WOW and a Win32 window proc. We
// used to achieve this by always setting the MSB of a 16:16 address as 1 (and
// storing the MSB in the Table indicator bit of the LDT which is always 1). The
// MSB of a user mode flat address was guranteed to be never 1 as the user mode
// address space was limited to 2GB. Starting with NT 5.0, user mode address
// space is being increased to 3GB. This change breaks the above assumption
// that a 32bit user mode flat address will never have the MSB as 1.
// To work around this problem, WOW is going to use the two bits of a
// 16:16 address instead of just one. We will set both these bits as 1 because
// with 3GB address space, the user mode flat addresses cannot have 11 as the
// first two bits. To achieve this, we will save the 2 most significant bits of
// the selector in the bit 1 and bit 2. We are able to do this because for WOW
// because both these bits have fixed values.
