From 4daa832d99871356f5fdc52372c975e40f73a15e Mon Sep 17 00:00:00 2001 From: Mathias Krause Date: Mon, 20 Jul 2015 18:32:53 +0200 Subject: [PATCH] x86: Drop bogus __ref / __refdata annotations The __ref / __refdata annotations used to be needed because of referencing functions / variables annotated __cpuinit / __cpuinitdata. But those annotations vanished during the development of v3.11. Therefore most of the __ref / __refdata annotations are not needed anymore. As they may hide legitimate sections mismatches, we better get rid of them. Signed-off-by: Mathias Krause Cc: Borislav Petkov Cc: Paul Gortmaker Cc: Peter Zijlstra Cc: Rafael J.
