From c392bccf2c1075b5d2cc9022d0116a516acb721d Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 20 Nov 2019 12:14:51 +1100 Subject: [PATCH] powerpc: Add const qual to local_read() parameter A patch in net-next triggered a compile error on powerpc: include/linux/u64_stats_sync.h: In function 'u64_stats_read': include/asm-generic/local64.h:30:37: warning: passing argument 1 of 'local_read' discards 'const' qualifier from pointer target type This seems reasonable to relax powerpc local_read() requirements.
