Subject: x86/asm/tsc: Replace rdtscll() with native_read_tsc()
X-Git-Tag: omap-for-v4.3/fixes-merge-window~19^2~80
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=87be28aaf1458445d5f648688c2eec0f13b8f3b9;p=pandora-kernel.git

x86/asm/tsc: Replace rdtscll() with native_read_tsc()

Now that the ->read_tsc() paravirt hook is gone, rdtscll() is
just a wrapper around native_read_tsc(). Unwrap it.
