    Subject[10/54] PCI: Do not run NVidia quirks related to MSI with MSI disabled
    2.6.34-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Rafael J. Wysocki <rjw@sisk.pl>

    commit 3d2a531804d16cd8df6dbbb0429c6f143e756049 upstream.

    There is no reason to run NVidia-specific quirks related to HT MSI
    mappings with MSI disabled via pci=nomsi, so make
    __nv_msi_ht_cap_quirk() return immediately in that case.

    This allows at least one machine to boot 100% of the time with
    pci=nomsi (it still doesn't boot reliably without that).

    Addresses https://bugzilla.kernel.org/show_bug.cgi?id=16443 .
