Apologies, we're in the process of getting LLD turned on. These
warnings look new to me, so I'll file an issue to follow up on. It's
unrelated to the yyloc change.

$ gzip -d .config.gz

ld.lld does not support AArch64 or ARM big endian:

https://reviews.llvm.org/D58655#1410281

https://github.com/ClangBuiltLinux/linux/issues/380

Does 0day do an allyesconfig little endian? I know that arm64 defaults
to little endian after commit d8e85e144bbe ("arm64: Kconfig: add a
choice for endianness") but arm does not have something like that (maybe
it should?). I've always forced CONFIG_CPU_LITTLE_ENDIAN with the
KCONFIG_ALLCONFIG variable, as I note in issue #380 above.

Kind of surprised that it got to drivers/staging though, I error out in
arch/arm/vdso/Makefile:

$ mkdir -p out/arm32 && curl -LSs 'https://lists.01.org/hyperkitty/list/kbuil...@lists.01.org/message/V6YPX24H2YFOKOE7FWFJ66DQI63R3WKZ/attachment/2/config.gz' | gzip -d > out/arm32/.config

$ make -j$(nproc) -s ARCH=arm CC=clang CROSS_COMPILE=arm-linux-gnueabi- LD=ld.lld O=out/arm32 olddefconfig all
ld.lld: error: unknown argument: --be8

got it, we will update build logic to keep lld where it suits.

currently no, the default arm allyes uses CONFIG_CPU_BIG_ENDIAN=y.
