Merge branch 'wireguard-patches-for-5-19-rc6'
Jason A. Donenfeld says: ==================== wireguard patches for 5.19-rc6 1) A few small fixups to the selftests, per usual. Of particular note is a fix for a test flake that occurred on especially fast systems that boot in less than a second. 2) An addition during this cycle of some s390 crypto interacted with the way wireguard selects dependencies, resulting in linker errors reported by the kernel test robot. So Vladis sent in a patch for that, which also required a small preparatory fix moving some Kconfig symbols around. ==================== Link: https://lore.kernel.org/r/20220707003157.526645-1-Jason@zx2c4.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
