[PATCH 1/5] ARM64: Split out CONFIG_ARM64_AARCH32 from CONFIG_COMPAT. Signed-off-by: Andrew Pinski <apinski at cavium.com>

Andrew Pinski pinskia at gmail.com
Mon Sep 9 17:32:55 EDT 2013 

Right now CONFIG_COMPAT means enabling AARCH32 support in the ARM64 traget, which we want to split out so we can it to mean any 32bit ABI support instead.
