From: James Morse james.morse@arm.com Date: Mon, 6 Nov 2017 18:44:27 +0000 Subject: ACPI / APEI: Remove arch_apei_flush_tlb_one()

From: James Morse james.morse@arm.com

commit 4a75aeacda3c2455954596593d89187df5420d0a upstream.

Nothing calls arch_apei_flush_tlb_one() anymore, instead relying on __set_pte_vaddr() to do the invalidation when called from clear_fixmap() Remove arch_apei_flush_tlb_one().
