Subject: [PATCH for-4.8 V2 02/10] powerpc/mm: Convert early cpu/mmu feature check to use the new helpers
Date: Sat, 23 Jul 2016 14:42:35 +0530 [thread overview]
Message-ID: <1469265163-1491-3-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1469265163-1491-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>
This switch the early feature check to use the non static key
variant of the function. In later patches we will be switching
cpu_has_feature and mmu_has_feature to use static keys and we can use
them only after static key/jump label is initialized. Any check for
feature before jump label init should be done using this new helper.
