From: Stefano Stabellini Date: Wed, 22 Aug 2012 16:20:15 +0000 (+0100) Subject: xen: clear IRQ_NOAUTOEN and IRQ_NOREQUEST X-Git-Tag: v3.7-rc1~128^2~19 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a8636c0;p=thirdparty%2Fkernel%2Flinux.git xen: clear IRQ_NOAUTOEN and IRQ_NOREQUEST Reset the IRQ_NOAUTOEN and IRQ_NOREQUEST flags that are enabled by default on ARM. If IRQ_NOAUTOEN is set, __setup_irq doesn't call irq_startup, that is responsible for calling irq_unmask at startup time. As a result event channels remain masked.
