Linux 5.11-rc6 compile error

Linux 5.11-rc6 compile error

[Shuah Khan]

I am seeing the following compile error on Linux 5.11-rc6.
No issues on 5.11.0-rc5 with the same config.

ld: arch/x86/built-in.a: member arch/x86/kernel/pci-swiotlb.o in archive 
is not an object
make: *** [Makefile:1170: vmlinux] Error 1

CONFIG_SWIOTLB_XEN=y
CONFIG_SWIOTLB=y

I can debug further later on today. Checking to see if there are any
known problems.

thanks,
-- Shuah

That honestly sounds like something went wrong earlier - things like
doing a system upgrade in the middle of the build, or perhaps running
out of disk space or similar.

I've not seen any other reports of the same, and google doesn't find
anything like that either.

Does it keep happening if you do a "git clean -dqfx" to make sure you
have no old corrupt object files sound and re-do the whole build?

My bad. I was playing with two test systems this morning and totally
lost track. All is well after a "make clean" and make.

Sorry for the noise.

Those config settings in allmodconfig builds for me.
