Dear stable kernel maintainers,

Please consider applying the following patch for LLVM_IAS=1 support on Chrome OS: commit 6e7b64b9dd6d "elfcore: fix building with clang"

Please find in the attached a slightly changed patch due to missing upstream commit 7a896028adcf. This patch would fix an issue similar to the one fixed by another upstream patch ( https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=l...) that has been included in 5.4.

But 78762b0e79bc ("x86/asm/32: Add ENDs to some functions and relabel with SYM_CODE_*") is in the 5.4.90 kernel release, so are you sure this is still correct and will work properly?

And your subject is odd, as again, that commit is already in 5.4.90 :)

I've just queued up 6e7b64b9dd6d ("elfcore: fix building with clang") to the 5.4.y queue directly, if it's incorrect, please let me know.

thanks,

greg k-h
