Hi Greg and Antonio, The stable-rc 5.4 build is failing. ( 5.10 and 5.15 builds pass ) because new build getting these two extra configs. CONFIG_GENERIC_COMPAT_VDSO=y CONFIG_COMPAT_VDSO=y These two configs are getting added by extra build variable CROSS_COMPILE_COMPAT=arm-linux-gnueabihf- This extra variable is coming from new tuxmake tool. Doesn't build 32 bit vDSO for arm64 https://gitlab.com/Linaro/tuxmake/-/issues/160 ref: https://qa-reports.linaro.org/lkft/linux-stable-rc-linux-5.4.y/ Reported-by: Linux Kernel Functional Testing <lkft@xxxxxxxxxx> -- Linaro LKFT https://lkft.linaro.org
