Re: [PATCH v5 4/8] x86/mm/tlb: Flush remote and local TLBs concurrently

Given that the last patch killed the last previously existing
user of on_each_cpu_cond_mask there are now the only users.

Which means the cond_func is unused, and thus on_each_cpu_cond_mask can
go away entirely in favor of on_each_cpu_cond.
