Subject: [PATCH 3.8 090/116] arm64/dma: Removing ARCH_HAS_DMA_GET_REQUIRED_MASK macro -stable review patch.  If anyone has any objections, please let me know.


From: Suravee Suthikulpanit <>

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)
