This is a note to let you know that I've just added the patch titled MIPS: BMIPS: Also call bmips_cpu_setup() for secondary cores to the 5.8-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: mips-bmips-also-call-bmips_cpu_setup-for-secondary-c.patch and it can be found in the queue-5.8 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit df2f8c28e3153f0ad54fb1001281ec4c77dea202 Author: Florian Fainelli <f.fainelli@xxxxxxxxx> Date: Wed Aug 19 11:26:45 2020 -0700 MIPS: BMIPS: Also call bmips_cpu_setup() for secondary cores [ Upstream commit e14f633b66902615cf7faa5d032b45ab8b6fb158 ] The initialization done by bmips_cpu_setup() typically affects both threads of a given core, on 7435 which supports 2 cores and 2 threads, logical CPU number 2 and 3 would not run this initialization.
