If anyone has any objections, please let me know. ------------------ [ Upstream commit d5654e156bc4d68a87bbaa6d7e020baceddf6e68 ] Make sure that the HPMC (High Priority Machine Check) handler is 16-byte aligned and that it's length in the IVT is a multiple of 16 bytes. Otherwise PDC may decide not to call the HPMC crash handler.
