The patch titled
Subject: s390/compat: change parameter types from unsigned long to compat_ulong_t
has been removed from the -mm tree. Its filename was
s390-compat-change-parameter-types-from-unsigned-long-to-compat_ulong_t.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Heiko Carstens <heiko.carstens@xxxxxxxxxx>
Subject: s390/compat: change parameter types from unsigned long to compat_ulong_t
Change parameter types of s390's compat ipc syscall from unsigned long to
compat_ulong_t to enforce zero extension of these parameters.
This is not really a bug, since s390_ipc compat syscall is only a wrapper
to the generic compat_sys_ipc() syscall, which performs correct zero and
sign extension.
This was introduced with 56e41d3c5aa84 "merge compat sys_ipc instances".
