Subject: [PATCH 0/2] sparc/module: R_SPARC_UA64 handling to help with LLVM
 IAS enablement

Hello~

This series lets the module loader handle R_SPARC_UA64, which is emitted
by LLVM's IAS in certain conditions. Additionally, I put on a small change
to the error log to make it clearer that the printed relocation number
is in hex.

The intention is to get both the kernel and LLVM in a state where
doing a clang+IAS build is possible.

As with before, on the LLVM side the project is tracked here:
https://github.com/llvm/llvm-project/issues/40792
