ARM randconfig builds with lld sometimes show a build failure from kallsyms: Inconsistent kallsyms data Try make KALLSYMS_EXTRA_PASS=1 as a workaround The problem is the veneers/thunks getting added by the linker extend the symbol table, which in turn leads to more veneers being needed, so it may take a few extra iterations to converge. This bug has been fixed multiple times before, but comes back every time a new symbol name is used. lld uses a different set of identifiers from ld.bfd, so the additional ones need to be added as well. I looked through the sources and found that arm64 and mips define similar prefixes, so I'm adding those as well, aside from the ones I observed. I'm not sure about powerpc64, which seems to already be handled through a section match, but if it comes back, the "__long_branch_" and "__plt_" prefixes would have to get added as well.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
