Subject: [PATCH v2 1/4] arm: processor: rename iss to res0 in hsr_cond union
Date: Wed, 9 Aug 2017 22:44:27 +0300 [thread overview]
Message-ID: <1502307870-11317-2-git-send-email-volodymyr_babchuk@epam.com> (raw)
In-Reply-To: <1502307870-11317-1-git-send-email-volodymyr_babchuk@epam.com>
Name "iss" in this case was used not exactly correctly, because this
is only part of HSR.ISS field. ARM refence manual denotes this
part of ISS as RES0 when it describes encoding for conditional
exceptions (ARM DDI 0487A.k pages D7-1939 - D7-1949).
