Subject: [PATCH 2/4] numa, iommu/io-pgtable-arm: Use NUMA aware memory allocation for smmu translation tables
Date: Thu, 21 Sep 2017 14:29:20 +0530 [thread overview]
Message-ID: <20170921085922.11659-3-ganapatrao.kulkarni@cavium.com> (raw)
In-Reply-To: <20170921085922.11659-1-ganapatrao.kulkarni@cavium.com>
function __arm_lpae_alloc_pages is used to allcoated memory for smmu
translation tables. updating function to allocate memory/pages
from the proximity domain of SMMU device.
