Subject: s390/setup: always inline gen_lpswe()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=029a4f4b9555ddb47f38f9589fd6d43277efb9c6;p=linux.git

s390/setup: always inline gen_lpswe()

gen_lpswe() contains a BUILD_BUG_ON() statement which depends on a function
parameter. If the compiler decides to generate a not inlined function this
will lead to a build error, even if all call sites pass a valid parameter.

To avoid this always inline gen_lpswe().
