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?
