Subject: [Qemu-devel] [PATCH 1/2] memory: allow zero size for adjust_endianness()
Date: Wed, 26 Aug 2015 18:04:07 +0800	[thread overview]
Message-ID: <1440583448-15797-1-git-send-email-jasowang@redhat.com> (raw)

Wildcard mmio eventfd use zero size, but it will lead abort() since it
was illegal in adjust_endianness(). Fix this by allowing zero size.
