From: Ingo Molnar Date: Wed, 27 Oct 2010 15:41:17 +0000 (+0200) Subject: percpu: Remove the multi-page alignment facility X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=47f19a0814e80e1d4e5c17d61b70fca85ea09162;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git percpu: Remove the multi-page alignment facility [DECLARE|DEFINE]_PER_CPU_MULTIPAGE_ALIGNED never really worked because the head percpu section was only page aligned. Now that the last user is gone (32-bit IRQ stacks), remove the generic percpu facility.
