    [PATCH] PCI: Change MSI to use physical delivery mode always · b4033c17
    Ashok Raj authored
    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.
