Subject: cpu/SMT: State SMT is disabled even with nosmt and without "=force"
X-Git-Tag: v4.9.203~38
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6270cc3754f9d94fdf42d859c1acfa5ced8ef08b;p=platform%2Fkernel%2Flinux-amlogic.git

cpu/SMT: State SMT is disabled even with nosmt and without "=force"

[ Upstream commit d0e7d14455d41163126afecd0fcce935463cc512 ]

When booting with "nosmt=force" a message is issued into dmesg to
confirm that SMT has been force-disabled but such a message is not
issued when only "nosmt" is on the kernel command line.

Fix that.
