Subject: [Qemu-devel] [PATCH v2] SPARC: Fix LEON3 power down instruction
Date: Wed, 27 Nov 2013 08:50:11 +0100 [thread overview]
Message-ID: <1385538611-8149-1-git-send-email-sebastian.huber@embedded-brains.de> (raw)
In-Reply-To: <CAFEAcA8DyS8ftustsMmQWGxmhMUNujVN25m+5d6XCPxQVj3d0A@mail.gmail.com>
Synchronize the program counter before the power down helper call
otherwise interrupts will return to the wrong context.
