MSI hardcoded delivery mode to use logical delivery mode. Recently x86_64 moved to use physical mode addressing to support physflat mode. With this mode enabled noticed that my eth with MSI werent working. msi_address_init() was hardcoded to use logical mode for i386 and x86_64. So when we switch to use physical mode, things stopped working. Since anyway we dont use lowest priority delivery with MSI, its always directed to just a single CPU. Its safe and simpler to use physical mode always, even when we use logical delivery mode for IPI's or other ioapic RTE's.
