[PATCH 3.15 104/139] arm64/dma: Removing ARCH_HAS_DMA_GET_REQUIRED_MASK macro

From: Greg Kroah-Hartman
Date: Sat Jun 28 2014 - 14:04:55 EST


3.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Suravee Suthikulpanit <Suravee.Suthikulpanit@xxxxxxx>

commit f3a183cb422574014538017b5b291a416396f97e upstream.

Arm64 does not define dma_get_required_mask() function.
Therefore, it should not define the ARCH_HAS_DMA_GET_REQUIRED_MASK.
This causes build errors in some device drivers (e.g. mpt2sas)
