Subject: init: Remove check_bugs() leftovers
From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
commit 61235b24b9cb37c13fcad5b9596d59a1afdcec30 upstream
Everything is converted over to arch_cpu_finalize_init(). Remove the
check_bugs() leftovers including the empty stubs in asm-generic, alpha,
parisc, powerpc and xtensa.
