When building with CONFIG_LTO_CLANG_FULL, there are several errors due to the way that parse_r is defined with an __asm__ statement in a header: ld.lld: error: ld-temp.o <inline asm>:105:1: macro 'parse_r' is already defined .macro parse_r var r ^ This was an issue for arch/mips as well, which was resolved by commit67512a8cf5("MIPS: Avoid macro redefinitions"). However, parse_r is unused in arch/loongarch after commit83d8b38967("LoongArch: Simplify the invtlb wrappers"), so doing the same change does not make much sense now. Just remove parse_r (and parse_v, which is also unused) to resolve the redefinition error. If it needs to be brought back due to an actual use, it should be brought back with the same changes as the aforementioned arch/mips commit.

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.
