You have just added some examples for hardening the kernel. Maybe you want read more here User:Pietinger/Tutorials/Kernel_Hardening_with_KSPP

Wording Queries
This is a really good new submission and one I think many people will find helpful so thanks for creating it.
I do have two queries though:
Here you have suggested using -O3, I know from testing using it systemwide this is generally slower so I think if you know in the case of kernel this is better it would be wise to add some results to show what to accept.
2. Kernel/Optimization#Clang.2FLLVM
Could you clarify what the warning is for on this one as you can use a LLVM compiled system with a GCC compiled kernel with very few issues nowadays as I'm running gentoo-kernel-bin on my system which is setup in this way.

- 1. You can see some results in Phoronix article. I might add my own benchmarks 2. What i meant is to not mix the binutils, for example make CC=gcc LD=ld.lld AR=llvm-ar will not work because LLVM's ar and ld is not compatible with GCC. -- Gso321 (talk) 17:25, 10 March 2023 (UTC)
