Subject: kconfig/x86: Add HAVE_TEXT_POKE_SMP config for stop_machine dependency
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3cba11d32bb4b24c3ba257043595772df4b9c7b5;p=linux-beck.git

kconfig/x86: Add HAVE_TEXT_POKE_SMP config for stop_machine dependency

Since the text_poke_smp() definately depends on actual
stop_machine() on smp, add that dependency to Kconfig.
