From b2e02b820d5b42479195b89d3d73f31bcedb264e Mon Sep 17 00:00:00 2001 From: Brian Gerst Date: Mon, 22 Jun 2015 07:55:11 -0400 Subject: [PATCH] x86/compat: Make mmap_is_ia32() common compat TIF_ADDR32 is set for both ia32 and x32 tasks, so change from CONFIG_IA32_EMULATION to CONFIG_COMPAT. Use config_enabled() to make the function more readable. Signed-off-by: Brian Gerst Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Denys Vlasenko Cc: H.
