Re: clang kernel PPC32 build failure, undefined reference to `__umoddi3'
Thanks for the report; tracking the issue here: https://github.com/ClangBuiltLinux/linux/issues/1679 clang-15 got more aggressive about eliminating loops outright; some cases can be replaced with division/remainder. LLVM is missing support for expanding 64b division by constant for 32b targets; WIP.

Looks like since recently some clang builds fails for missing reference to `__umoddi3`.

Your solution addresses all needs of current architectures. My proposal was just meant as preparation for the case, that new (smaller) architectures may come up in the future with a TRNG support, but with other granularity. But anyhow: we can handle it as soon as it happens, fine with me. -- Mit freundlichen Grüßen / Kind regards Holger Dengler -- IBM Systems, Linux on IBM Z Development deng...@linux.ibm.com

[PATCH] powerpc/64e: Fix kexec build error
When building ppc64_book3e_allmodconfig the build fails with:
arch/powerpc/kexec/file_load_64.c:1063:14: error: implicit declaration of
function ‘firmware_has_feature’
1063 | if (!firmware_has_feature(FW_FEATURE_LPAR))
| ^~~~
Add a direct include of asm/firmware.h to fix the error.
