[Linux-stable-mirror] Patch "x86/smpboot: Make optimization of delay calibration work correctly" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled x86/smpboot: Make optimization of delay calibration work correctly to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: x86-smpboot-make-optimization-of-delay-calibration-work-correctly.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 76ce7cfe35ef58f34e6ba85327afb5fbf6c3ff9b Mon Sep 17 00:00:00 2001 From: Pavel Tatashin <pasha.tatashin(a)oracle.com> Date: Fri, 27 Oct 2017 20:11:00 -0400 Subject: x86/smpboot: Make optimization of delay calibration work correctly From: Pavel Tatashin <pasha.tatashin(a)oracle.com> commit 76ce7cfe35ef58f34e6ba85327afb5fbf6c3ff9b upstream. If the TSC has constant frequency then the delay calibration can be skipped when it has been calibrated for a package already. This is checked in calibrate_delay_is_known(), but that function is buggy in two aspects: It returns 'false' if (!tsc_disabled && !cpu_has(&cpu_data(cpu), X86_FEATURE_CONSTANT_TSC) which is obviously the reverse of the intended check and the check for the sibling mask cannot work either because the topology links have not been set up yet. Correct the condition and move the call to set_cpu_sibling_map() before invoking calibrate_delay() so the sibling check works correctly.
