Subject: [PATCH] iommu/io-pgtable-arm: Add built time dependency
Date: Fri, 20 Feb 2015 19:44:45 +0100 [thread overview]
Message-ID: <20150220194445.4225d56b@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.
