Subject: x86/alternatives: Remove 'smp_text_poke_batch_flush()'
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=2c373ca0640f25361aee1bcf382fc8081830938e;p=users%2Fdwmw2%2Flinux.git

x86/alternatives: Remove 'smp_text_poke_batch_flush()'

It only has a single user left, merge it into smp_text_poke_batch_add()
and remove the helper function.
