From: Stefano Stabellini Date: Wed, 8 Aug 2012 17:20:36 +0000 (+0000) Subject: xen: clear IRQ_NOAUTOEN and IRQ_NOREQUEST X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=fb94522b3bb90de6641d7c691aca4d73deefce7e;p=people%2Fsstabellini%2Flinux-pvhvm-deprecated.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.
