[PATCH 0/2] Refactor dummy DMA ops

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Tangential to Christoph's RFC for mitigating indirect call overhead in
common DMA mapping scenarios[1], this is a little reshuffle to prevent the
CONFIG_ACPI_CCA_REQUIRED case from getting in the way. This would best go
via the dma-mapping tree, so reviews and acks welcome.

Robin.
