[Fix] * Backport fix from upstream commit f47729b94e11 (backport: rename ktime_get_boot_ns for v5.3+). * Also updates -fcf-protection=none usage for bug 1830961. [Test Case] Verified DKMS module build on linux-oem/linux-oem-osp1/linux-generic >= 4.10 kernels on series Xenial/Bionic/Cosmic/Disco/Eoan and Focal. [Regression Risk] Low. There is no functional changes in comparison to 7906-0ubuntu1. ======== original bug description ======== Compiling kernels & kernel modules fails due to these errors: ./include/linux/compiler.h:193:1: error: ‘-mindirect-branch’ and ‘-fcf-protection’ are not compatible (This happens with any kernel modules.) This appears to be due to the changes in 9.1.0-3ubuntu1 enabling -fcf- protection by default on 19.10's gcc-9. Switching to gcc-8 allows compilation to proceed.
