Subject[PATCH] mce: acpi/apei: Only disable banks listed in HEST if mce is configured
From: "Naveen N. Rao" <naveen.n.rao@linux.vnet.ibm.com>

Randconfig testing found this error:
>> hest.c(.init.text+0x6004): undefined reference to 'mce_disable_bank'

Fix by wrapping body of hest_parse_cmc() inside #ifdef CONFIG_X86_MCE

Reported-by: "Wu, Fengguang" <fengguang.wu@intel.com>

[Peter: Thanks for pulling Naveen's series from my ras tree. Fengguang's
testbuild robot promtly found this build issue. Please apply this patch
on top of the x86/mce branch. - Thanks]
