Subject: [RFC PATCH 03/15] FIXME: mips: fix copy_to_link_location for 64 bit mode
Date: Thu, 17 May 2018 16:58:46 +0300	[thread overview]
Message-ID: <20180517135858.16202-4-pmamonov@gmail.com> (raw)
In-Reply-To: <20180517135858.16202-1-pmamonov@gmail.com>

A better solution: use 4 instead of LONGSIZE
