IS_ENABLED should be reserved for CONFIG_<FOO> uses so convert
the uses of IS_ENABLED with a #define to __is_defined.

s390: detect etoken facility2018-07-18T06:32:17ZMartin Schwidefskyschwidefsky@de.ibm.com2018-05-08T13:14:48Zurn:sha1:aeaf7002a76c8da60c0f503badcbddc07650678c
Detect and report the etoken facility. With spectre_v2=auto or
CONFIG_EXPOLINE_AUTO=y automatically disable expolines and use
the full branch prediction mode for the kernel.

s390: move spectre sysfs attribute code2018-05-07T19:12:41ZMartin Schwidefskyschwidefsky@de.ibm.com2018-04-24T06:23:54Zurn:sha1:4253b0e0627ee3461e64c2495c616f1c8f6b127b
The nospec-branch.c file is compiled without the gcc options to
generate expoline thunks. The return branch of the sysfs show
functions cpu_show_spectre_v1 and cpu_show_spectre_v2 is an indirect
branch as well. These need to be compiled with expolines.
Move the sysfs functions for spectre reporting to a separate file
and loose an '.' for one of the messages.
