From: Al Viro <v...@zeniv.linux.org.uk>
--EWB Added #ifdef CONFIG_X86_X32_ABI to arch/x86/kernel/signal_compat.c
Changed #ifdef CONFIG_X86_X32 to #ifdef CONFIG_X86_X32_ABI in
linux/compat.h
CONFIG_X86_X32 is set when the user requests X32 support.
CONFIG_X86_X32_ABI is set when the user requests X32 support
and the tool-chain has X32 allowing X32 support to be built.
Signed-off-by: Al Viro <v...@zeniv.linux.org.uk>
