[Qemu-trivial] [PATCH 2/3] linux-user: fixed getsockopt() optlen


From: pavel . zbitskiy
Subject: [Qemu-trivial] [PATCH 2/3] linux-user: fixed getsockopt() optlen
Date: Sat, 11 Jan 2014 13:34:10 +0400

From: Pavel Zbitskiy <address@hidden>

optlen parameter of getsockopt() of type socklen_t* was read into
variable of type socklen_t, that caused zeroing out of upper 4 bytes
when running s390x on top of x86_64. This patch changes optlen type
to abi_ulong.
