Subject: [PATCH 2/2] EDAC, altera: Add IRQ Flags to disable IRQ while handling
Date: Thu, 22 Sep 2016 17:13:39 -0500 [thread overview]
Message-ID: <1474582419-7053-2-git-send-email-tthayer@opensource.altera.com> (raw)
In-Reply-To: <1474582419-7053-1-git-send-email-tthayer@opensource.altera.com>
From: Thor Thayer <tthayer@opensource.altera.com>
Add the IRQF_ONESHOT and IRQF_TRIGGER_HIGH flags to disable the
IRQ while executing the IRQ handler. Remove the IRQF_SHARED because
these are not shared IRQs in the domain. Exposed when flooding IRQs.
