Subject: [PATCH v2] iommu/io-pgtable-arm: Add built time dependency
Date: Mon, 23 Feb 2015 10:05:21 +0100 [thread overview]
Message-ID: <20150223100521.45108573@endymion.delvare> (raw)
If io-pgtable-arm is an ARM-specific driver then configuration option
IOMMU_IO_PGTABLE_LPAE should not be presented to the user by default
for non-ARM kernels.
