This parameter was misinterpreted as an alignment parameter for the lower bits of the allocated memory region, although it is a constraint on the higher bits.
Add a new internal ntdll virtual_alloc_aligned function that has a separate alignment parameter which is now used instead of the zero_bits parameter.
