I put the patches in these bugzillas:

    https://bugzilla.kernel.org/show_bug.cgi?id=16228 (Dell T3500)
    https://bugzilla.kernel.org/show_bug.cgi?id=23132 (Dell 1545)
    https://bugzilla.kernel.org/show_bug.cgi?id=23542 (HP 2530p)
    https://bugzilla.kernel.org/show_bug.cgi?id=23802 (PCI / TPM conflict)

Bernard Wiedemann reported success for 16228 on a Dell T3500.  No
news yet on the others.

For this one:

    https://bugzilla.kernel.org/show_bug.cgi?id=23332 (HP nx6325)

I have an nx6325 and tested it myself.
