Subject: s390: Remove extra check of task_stack_page()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a59b9cb8596ce82a5a8d4dda417e1a721158ed53;p=thirdparty%2Fkernel%2Flinux.git

s390: Remove extra check of task_stack_page()

There is no need to call task_stack_page(),
because try_get_task_stack() already takes care of that.
