+Subject: [PATCH] hw/pl031: Actually raise interrupt on timer expiry
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Fix a typo in pl031_interrupt() which meant we were setting a bit
+in the interrupt mask rather than the interrupt status register
+and thus not actually raising an interrupt. This fix allows the
+rtctest program from the kernel's Documentation/rtc.txt to pass
+rather than hanging.
