Subject: [PATCH v6 02/21] arm64: ensure the kernel is compiled for LP64
Date: Fri, 8 Jan 2016 02:34:20 +0300 [thread overview]
Message-ID: <1452209679-19445-3-git-send-email-ynorov@caviumnetworks.com> (raw)
In-Reply-To: <1452209679-19445-1-git-send-email-ynorov@caviumnetworks.com>
From: Andrew Pinski <apinski@cavium.com>
The kernel needs to be compiled as a LP64 binary for ARM64, even when
using a compiler that defaults to code-generation for the ILP32 ABI.
Consequently, we need to explicitly pass '-mabi=lp64' (supported on
gcc-4.9 and newer).
