From 811f5ce823178b96ac04a770e90854ba98a8d67e Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Thu, 18 Jul 2013 11:32:01 -0700 Subject: [PATCH] kconfig: switch to "long long" for sanity Instead of using "long" for kconfig "hex" and "range" values, which may change in size depending on the host architecture, use "long long". This will allow values greater than INT_MAX on 32-bit hosts when cross compiling. Signed-off-by: Kees Cook Acked-by: Geert Uytterhoeven Tested-by: "Yann E. MORIN" Signed-off-by: "Yann E.
