The linux changes since v3.16 are
78283edf2c01 kbuild: setlocalversion: print error to STDERR b24413180f56 License cleanup: add SPDX GPL-2.0 license identifier to files with no license 6147b1cf1965 scripts/setlocalversion: git: Make -dirty check more robust 8ef14c2c41d9 Revert "scripts/setlocalversion: git: Make -dirty check more robust" ff64dd485730 scripts/setlocalversion: Improve -dirty check with git-status --no-optional-locks 7a82e3fa28f1 scripts/setlocalversion: clear local variable to make it work for sh 991b78fbd223 scripts: setlocalversion: fix a bashism 3c96bdd0ebfa scripts: setlocalversion: replace backquote to dollar parenthesis
and it's ff64dd485730 that is the motivation for this sync. It fixes false positive "-dirty" added to the version string when building with Yocto (https://lists.openembedded.org/g/openembedded-core/message/137702).
There has been one U-Boot specific patch since this was synced with linux 3.16: 81630a3b38c2 (scripts: setlocalversion: safely extract variables from auto.conf using awk). However, it seems that since a356e7a86b (spl: Kconfig: Escape '$(ARCH)' in LDSCRIPT entries), auto.conf doesn't contain the $(ARCH) string but instead the actual value of ARCH.
So for now, use the linux version as-is; it should be fairly obvious if 81630a3b38c2 or something like it does need to be applied on top.
