>From 529d30309769b0c9a40d0a4bd78ad54e8faec105 Mon Sep 17 00:00:00 2001 From: Andrew Pinski Date: Tue, 25 Aug 2015 02:26:54 +0300 Subject: [PATCH] arm64:uapi: set __BITS_PER_LONG correctly for ILP32 and LP64 Define __BITS_PER_LONG depending on the ABI used (i.e. check whether __ILP32__ or __LP64__ is defined). This is necessary for glibc to determine the appropriate type definitions for the system call interface.
