target/linux/rb532/patches-2.6.28/015-korina_irqf_flags.patch

   1 As the kernel warning states: "IRQF_DISABLED is not guaranteed on shared
   2 IRQs". Since these IRQs' values are hardcoded and my test system doesn't
   3 show any shared use of IRQs at all, rather make them non-shared than
   4 non-disabled.
