    Subject[34-longterm 179/247] x86, quirk: Fix SB600 revision check
    Date
    From: Andreas Herrmann <andreas.herrmann3@amd.com>

    -------------------
    This is a commit scheduled for the next v2.6.34 longterm release.
    If you see a problem with using this for longterm, please comment.
    -------------------

    commit 1d3e09a304e6c4e004ca06356578b171e8735d3c upstream.

    Commit 7f74f8f28a2bd9db9404f7d364e2097a0c42cc12
    (x86 quirk: Fix polarity for IRQ0 pin2 override on SB800
    systems) introduced a regression. It removed some SB600 specific
    code to determine the revision ID without adapting a
    corresponding revision ID check for SB600.

    See this mail thread:

    http://marc.info/?l=linux-kernel&m=129980296006380&w=2

    This patch adapts the corresponding check to cover all SB600
    revisions.
