  1. [PATCH 0/2][stable] x86: check correctness of IRQ0 override on systems with ATI/AMD SB450/SB600 chipsets

    Hi,

    following patches should go into 2.6.27-stable tree.

    They fix issues with HP Laptops that provide a wrong override for IRQ0
    and which change the thermal trip point as soon as Linux unmasks
    IOAPIC INT2.

    See for instance following bugzillas:

    Are these patches in the upstream Linus kernel already?

    If so, can you please give us the git commit ids?

    thanks,

    The one for SB450 is upstream. It's commit
    33fb0e4eb53f16af312f9698f974e2e64af39c12

    The second one was posted yesterday and it is not yet commited.

    BTW, I just posted another patch to remove superfluos DMI-quirks
    that are related to HP Laptops with SB450/SB600.
    IMHO this patch should go into stable as well. But first I'd like
    to get a response from Ingo here.


    Regards,

    Andreas

    That one is already added to the tree.

    Please let us know when it makes it upstream.

    Sure, just let us know when it goes upstream if you want it in -stable.

    That patch is now in Linus's tree, but it doesn't apply. Can you
    backport it to 2.6.27.3 and send it to stable@kernel.org if you still
    want this change to be in the 2.6.27 tree?

    thanks,
