Subject: [PATCH V6 7/8] powerpc: Check arch.vec earlier during boot for memory features
Date: Wed, 21 Sep 2016 09:17:45 -0500	[thread overview]
Message-ID: <d6614f82-0c59-8457-188a-3f6dcaa92bb3@linux.vnet.ibm.com> (raw)

architecture.vec5 features: The boot-time memory management needs to
know the form of the "ibm,dynamic-memory-v2" property early during
scanning of the flattened device tree.  This patch moves execution of
the function pseries_probe_fw_features() early enough to be before
the scanning of the memory properties in the device tree to allow
recognition of the supported properties.

[V2: No change]
[V3: Updated after commit 3808a88985b4f5f5e947c364debce4441a380fb8.]
[V4: Update comments]
[V5: Resynchronize/resubmit]
[V6: Resync to v4.7 kernel code]
