From b4b3bd96f26586e53ab5482f1869221dd1b5ac36 Mon Sep 17 00:00:00 2001 From: Daniel Rahn Date: Fri, 6 Jun 2008 09:42:36 +0200 Subject: [PATCH] x86: correctly report NR_BANKS in mce_64.c attached is a no-brainer that makes kernel correctly report NR_BANKS for MCE. We are right now limited to NR_BANKS==6, but the error message will use the available number of banks instead of the defined maximum. For a Nehalem based system it will print: "MCE: warning: using only 9 banks" while the correct message would be "MCE: warning: using only 6 banks" Signed-off-by: Pavel Machek Signed-off-by: Ingo Molnar --- arch/x86/kernel/cpu/mcheck/mce_64.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/x86/kernel/cpu/mcheck/mce_64.c b/arch/x86/kernel/cpu/mcheck/mce_64.c index f1f3f5e163b..8c8299ce7ad 100644 --- a/arch/x86/kernel/cpu/mcheck/mce_64.c +++ b/arch/x86/kernel/cpu/mcheck/mce_64.c @@ -445,9 +445,9 @@ static void mce_init(void *dummy) rdmsrl(MSR_IA32_MCG_CAP, cap); banks = cap & 0xff; if (banks > MCE_EXTENDED_BANK) { + banks = MCE_EXTENDED_BANK; printk(KERN_INFO "MCE: warning: using only %d banks\n", MCE_EXTENDED_BANK); - banks = MCE_EXTENDED_BANK; } /* Use accurate RIP reporting if available. */ if ((cap & (1<<9)) && ((cap >> 16) & 0xff) >= 9) -- 2.41.1
