Re: [git pull] IOMMU Updates for Linux v4.1

[Oded Gabbay <oded.gabbay@amd.com>]

Hi Joerg,

I sent to you (cc iommu mailing list) an important fix on Apr-16 for a bug in 
amd_iommu_v2.c (from kernel 4.0). See:
http://lists.linuxfoundation.org/pipermail/iommu/2015-April/012757.html

Could you please add that to the pull request ?
Its creating problems when running HSA applications.

Thanks,

	Oded
