Subject: [PATCH 4.14 042/104] x86/cpu/AMD: Remove the pointless detect_ht() call

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Gleixner <tglx@...utronix.de>

commit 44ca36de56d1bf196dca2eb67cd753a46961ffe6 upstream

Real 32bit AMD CPUs do not have SMT and the only value of the call was to
reach the magic printout which got removed.
