The downside is the double this_cpu_ptr() now on the
arch_leave_lazy_mmu_mode() path.
This is only temporary, patch 9 removes it from arch_enter(). I don't
think having a redundant this_cpu_ptr() for a few commits is really a
concern?
Oh, right. Consider mentioning in the patch description
"Note that follow-up patches will remove the double this_cpu_ptr() on
the arch_leave_lazy_mmu_mode() path again."
