[PATCH 5.4 049/149] s390/processor: always inline stap() and __load_psw_mask()

From: Greg Kroah-Hartman

From: Heiko Carstens <hca@xxxxxxxxxxxxx>

[ Upstream commit 9c9a915afd90f7534c16a71d1cd44b58596fddf3 ]

s390 is the only architecture which makes use of the __no_kasan_or_inline
attribute for two functions. Given that both stap() and __load_psw_mask()
are very small functions they can and should be always inlined anyway.

Therefore get rid of __no_kasan_or_inline and always inline these
functions.
