Subject: [PATCH 07/20] arm64:uapi: set __BITS_PER_LONG correctly for ILP32 and LP64
Date: Mon, 9 Jan 2017 16:59:44 +0530	[thread overview]
Message-ID: <1483961397-8599-8-git-send-email-ynorov@caviumnetworks.com> (raw)
In-Reply-To: <1483961397-8599-1-git-send-email-ynorov@caviumnetworks.com>

From: Andrew Pinski <apinski@cavium.com>

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.
