From d2313da4ff56bd631a3afe7a17992ed5bd0e04a6 Mon Sep 17 00:00:00 2001 From: He Ying Date: Tue, 16 Mar 2021 00:11:48 -0400 Subject: powerpc/setup_64: Fix sparse warnings Sparse warns: warning: symbol 'rfi_flush' was not declared. warning: symbol 'entry_flush' was not declared. warning: symbol 'uaccess_flush' was not declared. Define 'entry_flush' and 'uaccess_flush' as static because they are not referenced outside the file. Include asm/security_features.h in which 'rfi_flush' is declared.
