From 9a431bd5a26ca7db8ab251a75e006aa8b145718e Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 25 Jun 2015 10:44:08 +0100 Subject: [PATCH] ARM: make highpte an expert option When highmem is enabled, there's little reason not to also enable highpte support as well. Rather than leaving this to chance, make it an expert option, and default it to be enabled if highmem is enabled. Add some help text to the option while we're here.
