I suspect these bits are the ones that broke the upstream build:

 drivers/pci/dmar.c:47: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘dmar_tbl_size’
 drivers/pci/dmar.c:62: warning: ‘struct acpi_dmar_device_scope’ declared inside parameter list
 drivers/pci/dmar.c:62: warning: its scope is only this definition or declaration, which is probably not what you want

config attached.
