StephenR,

I'm not very familiar with git diff for merge conflicts, so I might be
wrong here, but I did reproduce this conflict to investigate, and I
think your fixup isn't quite correct.

I think you're left with two separate copies of the macro
arch_ret_to_user, and your conflict resolution diff should be more like
that below:

diff --git a/arch/arm/mach-tegra/include/mach/entry-macro.S
b/arch/arm/mach-tegra/include/mach/entry-macro.S
index ac11262..e577cfe 100644
--- a/arch/arm/mach-tegra/include/mach/entry-macro.S

Thanks for the work on linux-next.
