commit ee68555b979e6add431ed7cb0f965b36cc309ebb
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBL4B6

--------------------------------

commit 711b5875814b2a0e9a5aaf7a85ba7c80f5a389b1 upstream.

arch-s390.h uses types from std.h, but does not include it.
Depending on the inclusion order the compilation can fail.
Include std.h explicitly to avoid these errors.
