Subject: x86/smpboot: remove redundant CONFIG_SCHED_SMT
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=992de2b02509bed68f693ea5a68b07cd586197b7;p=thirdparty%2Fkernel%2Fstable.git

x86/smpboot: remove redundant CONFIG_SCHED_SMT

On x86 CONFIG_SCHED_SMT is default y if SMP is enabled, so let's
simply drop CONFIG_SCHED_SMT.
