Hi Mark, Will,
I have been trying to debug some perf builtin tests on ARM 32-bit and
found that "Breakpoint overflow signal handler" and "Breakpoint overflow

Hi all,
I tried that patch mentioned by Mimi but it does not change anything for me.

When a UHID_CREATE command is written to the uhid char device, a

A2XX has its own very simple MMU.
Added a msm_use_mmu() function because we can't rely on iommu_present to
decide to use MMU or not.
