Subject: [PATCH 4.4 01/99] MIPS64: R6: R2 emulation bugfix
Date: Sun, 5 Jun 2016 14:40:34 -0700 [thread overview]
Message-ID: <20160605213903.127819462@linuxfoundation.org> (raw)
In-Reply-To: <20160605213902.974592018@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Leonid Yegoshin <Leonid.Yegoshin@imgtec.com>
commit 41fa29e4d8cf4150568a0fe9bb4d62229f9caed5 upstream.
Error recovery pointers for fixups was improperly set as ".word"
which is unsuitable for MIPS64.
Replaced by STR(PTR)
