Subject: [S390] Move psw_set_key.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dc74d7f996b465d8a95033c753d34c8b4c01c9d7;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[S390] Move psw_set_key.

Move psw_set_key() from ptrace.h to processor.h which is a more
suitable place for it. In addition the moves makes the function
invisible to user space.
