Subject: [PATCH v2 09/22] arm64: Convert to generic memblock for numa-info
Date: Sun, 12 Jul 2020 09:26:54 -0700
Message-ID: <159457121480.754248.17292511837648775358.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <159457116473.754248.7879464730875147365.stgit@dwillia2-desk3.amr.corp.intel.com>

Drop the existing memory_add_physaddr_to_nid() stub and add support for
phys_to_target_node() by selecting the generic CONFIG_MEMBLOCK_NUMAINFO
mechanism for querying firmware numa data at runtime.
