Subject: [PATCH 03/10] arch/x86/platform/uv: BAU replace uv_physnodeaddr
Date: Tue, 20 Sep 2016 17:21:09 -0500 [thread overview]
Message-ID: <1474410076-178329-4-git-send-email-abanman@sgi.com> (raw)
In-Reply-To: <1474410076-178329-1-git-send-email-abanman@sgi.com>
The BAU driver should use the functions provided by uv_hub.h rather than
its own implementations. uv_physnodeaddr converts vaddrs to paddrs for
BAU MMR fields, but this is done better by uv_gpa_to_offset.
