From e53281bc21f061f96c9004f534bc3e807d70cb73 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Fri, 14 Aug 2020 06:54:49 +0000 Subject: powerpc: Drop _nmask_and_or_msr() _nmask_and_or_msr() is only used at two places to set MSR_IP. The SYNC is unnecessary as the users are not PowerPC 601. Can be easily writen in C. Do it, and drop _nmask_and_or_msr() Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/c2d2b8dfb8dd677026b26dffc8d31070c38a6b89.1597388079.git.christophe.leroy@csgroup.eu --- arch/powerpc/kernel/misc_32.S | 13 ------------- 1 file changed, 13 deletions(-) (limited to 'arch/powerpc/kernel/misc_32.S') diff --git a/arch/powerpc/kernel/misc_32.S b/arch/powerpc/kernel/misc_32.S index b24f866fef81..8d9cb5df580e 100644 --- a/arch/powerpc/kernel/misc_32.S +++ b/arch/powerpc/kernel/misc_32.S @@ -215,19 +215,6 @@ _GLOBAL(low_choose_7447a_dfs) #endif /* CONFIG_CPU_FREQ_PMAC && CONFIG_PPC_BOOK3S_32 */ -/* - * complement mask on the msr then "or" some values on. - * _nmask_and_or_msr(nmask, value_to_or) - */ -_GLOBAL(_nmask_and_or_msr) - mfmsr r0 /* Get current msr */ - andc r0,r0,r3 /* And off the bits set in r3 (first parm) */ - or r0,r0,r4 /* Or on the bits in r4 (second parm) */ - SYNC /* Some chip revs have problems here... */ - mtmsr r0 /* Update machine state */ - isync - blr /* Done */ - #ifdef CONFIG_40x /* -- cgit
