-Subject: [PATCH 085/203] irqchip: armada-370-xp: fix IPI race condition
-
-In the Armada 370/XP driver, when we receive an IRQ 0, we read the
-list of doorbells that caused the interrupt from register
-ARMADA_370_XP_IN_DRBEL_CAUSE_OFFS. This gives the list of IPIs that
-were generated. However, instead of acknowledging only the IPIs that
-were generated, we acknowledge *all* the IPIs, by writing
-~IPI_DOORBELL_MASK in the ARMADA_370_XP_IN_DRBEL_CAUSE_OFFS register.
-
-This creates a race condition: if a new IPI that isn't part of the
-ones read into the temporary "ipimask" variable is fired before we
-acknowledge all IPIs, then we will simply loose it. This is causing
-scheduling hangs on SMP intensive workloads.
-
-It is important to mention that this ARMADA_370_XP_IN_DRBEL_CAUSE_OFFS
-register has the following behavior: "A CPU write of 0 clears the bits
-in this field. A CPU write of 1 has no effect". This is what allows us
-to simply write ~ipimask to acknoledge the handled IPIs.
-
-Notice that the same problem is present in the MSI implementation, but
-it will be fixed as a separate patch, so that this IPI fix can be
-pushed to older stable versions as appropriate (all the way to 3.8),
-while the MSI code only appeared in 3.13.
