Greetings,
After downloading this new patch and patching the 5.4.119 kernel sources
for arm through "./scripts/prepare-kernel.sh", I'm facing kernel
compiling issues with the "sama5_defconfig" configuration:

I'm using the Linaro ARM 2018.05 toolchain (Linaro GCC 7.3-2018.05), but
I also tried with another toolchain (gcc 10.2), and getting the same issue.
I don't have any trouble with ipipe-core-4.19.144-arm-10.patch on
sama5_defconfig.
Does it ring a bell to anyone?
Cheers,
Michael.
