Subject: [PATCH] ARM: Fix typo "CONFIG_LPAE" twice

Signed-off-by: Paul Bolle <pebolle@...cali.nl>

0) Untested.

1) This typo was first introduced in v3.4: commit
e5ab85800820edd907d3f43f285e1232f84d5a41 ("ARM: 7382/1: mm: truncate
memory banks to fit in 4GB space for classic MMU"). The second instance
was added in v3.9-rc2: commit d61947a164760ac520cb416768afdf38c33d60e7
(" ARM: 7657/1: head: fix swapper and idmap population with LPAE and
big-endian"). So testing is really needed here.

2) If this passes (review and) testing, this probably needs to go to
stable too.
