Re: [PATCH 4/5] sh: split arch/sh/mm/consistent.c

Hi Christoph, I have a single comment on something I noticed which might be an implementation bug. On the overall patch architecture, it's very hard for me to provide a valuable opinion as it's all relatively new for me here :) On Thu, Jul 19, 2018 at 06:05:15AM -0700, Christoph Hellwig wrote: >

[RESEND 1/6] iommu/ipmmu-vmsa: Increase maximum micro-TLBS to 48

From: Magnus Damm Bump up the maximum numbers of micro-TLBS to 48. Each IPMMU device instance get micro-TLB assignment via the "iommus" property in DT. Older SoCs tend to use a maximum number of 32 micro-TLBs per IPMMU instance however newer SoCs such as r8a7796 make use of up to 48 micro-TLBs.
