From 4d66bcc7cf762e82703b94d416245d4a216c79ae Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Tue, 14 Apr 2015 15:45:45 -0700 Subject: ia64: expose number of page table levels on Kconfig level We would want to use number of page table level to define mm_struct. Let's expose it as CONFIG_PGTABLE_LEVELS. We need to define PGTABLE_LEVELS before sourcing init/Kconfig: arch/Kconfig will define default value and it's sourced from init/Kconfig.
