Subject: x86/tsc: Make recalibrate_cpu_khz() export GPL only
X-Git-Tag: v6.3-rc1~184^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8fe6d84947582e2c076abc6253b80709fb047935;p=thirdparty%2Fkernel%2Flinux.git

x86/tsc: Make recalibrate_cpu_khz() export GPL only

A quick search doesn't reveal any use outside of the kernel - which
would be questionable to begin with anyway - so make the export GPL
only.
