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

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