This patchset from Stephen (includes "2/2 ARM: tegra: enable workaround for ARM erratum 716044") are both assigned to you in PatchWork, but haven't been applied yet to ARM/master AFAICT. I found them when I was searching for unapplied Tegra patches.
Could you please take this in thru the ARM tree ASAP?
Thanks,
Tom

Add common code to enable the workaround for ARM erratum 716044. This will be enabled for Tegra.

This depends on my previous ARM errata series. I found out we needed another one after I wrote the first series.
