Subject: [patch 2/6] h8300: Use schedule_preempt_irq
Date: Tue, 17 Sep 2013 18:53:06 -0000 [thread overview]
Message-ID: <20130917183628.646285522@linutronix.de> (raw)
In-Reply-To: 20130917182350.449685712@linutronix.de
[-- Attachment #1: h8300-use-schedule-preempt-irq.patch --]
[-- Type: text/plain, Size: 889 bytes --]
Use the proper function instead of fiddling with PREEMPT_ACTIVE and
interrupt enable/disable in the low level code.
