2014-09-01MdePkg BaseLib NASM Thunk16: Initialize _16GdtrBase to 0Jordan Justen
Previously we were setting it to the start of the GDT in the UEFI driver's copy of BaseLib. This address is irrelavent, since the C code will initialize it to the cooresponding address after the Thunk16 code has been placed in low memory. Additionally, initializing this was causing a link error for the XCLANG toolchain.
