I decided to dig out a toy project which uses a DragonBoard 410c. This has been "running" with kernel 4.9, which I would keep this way for unrelated reasons. The vanilla 4.9 kernel wasn't bootable back then, but it was buildable, which was good enough.
Upgrading the kernel to 4.9.180 caused the boot to suddenly fail:
aarch64-unknown-linux-gnueabi-ld: ./drivers/firmware/efi/libstub/lib.a(arm64- stub.stub.o): in function `handle_kernel_image': /tmp/e2/build/linux-4.9.139/drivers/firmware/efi/libstub/arm64-stub.c:63 : undefined reference to `__efistub__GLOBAL_OFFSET_TABLE_' aarch64-unknown-linux-gnueabi-ld: ./drivers/firmware/efi/libstub/lib.a(arm64- stub.stub.o): relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `__efistub__GLOBAL_OFFSET_TABLE_' which may bind externally can not be used when making a shared object; recompile with -fPIC /tmp/e2/build/linux-4.9.139/drivers/firmware/efi/libstub/arm64-stub.c:63 : (.init.text+0xc): dangerous relocation: unsupported relocation /tmp/e2/build/linux-4.9.139/Makefile:1001: recipe for target 'vmlinux' failed -make[1]: *** [vmlinux] Error 1
This is caused by commit 27b5ebf61818749b3568354c64a8ec2d9cd5ecca from linux-4.9.y (which is 91ee5b21ee026c49e4e7483de69b55b8b47042be), reverting this commit fixes the build.
This happens with vanilla binutils 2.32 and gcc 8.3.0 as well as 9.1.0. See the attached .config for reference.
If you have questions or patches just ping me.
Does Linus's latest tree also fail for you (or 5.1)?
5.1.7 with the same config as before and "make olddefconfig" builds for me.
Just for the fun of it: both 4.19 and 4.19.48 also work.
