Peter Zijlstra ed53a0d971 x86/alternative: Use .ibt_endbr_seal to seal indirect calls ... Objtool's --ibt option generates .ibt_endbr_seal which lists superfluous ENDBR instructions. That is those instructions for which the function is never indirectly called. Overwrite these ENDBR instructions with a NOP4 such that these function can never be indirect called, reducing the number of viable ENDBR targets in the kernel.
