Subject: [PATCH 4.14 10/44] ARCv2: [plat-hsdk]: Save accl reg pair by default
Date: Mon, 23 Jul 2018 14:24:46 +0200 [thread overview]
Message-ID: <20180723122437.939085285@linuxfoundation.org> (raw)
In-Reply-To: <20180723122437.447870153@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vineet Gupta <vgupta@synopsys.com>
commit af1fc5baa724c63ce1733dfcf855bad5ef6078e3 upstream.
This manifsted as strace segfaulting on HSDK because gcc was targetting
the accumulator registers as GPRs, which kernek was not saving/restoring
by default.

Depending on the configuration, CPU can contain accumulator reg-pair
(also referred to as r58:r59). These can also be used by gcc as GPR so
