This series provides a common way to call an arch's ioremap_exec, which currently only exists for ARM, so that we can use it in the generic sram driver in a forthcoming patch. This patch is part of a patch series split into several smaller sets for introducing suspend on AM335x. I plan to use it to copy several pieces of ASM code from an EMIF driver and the SoC PM code to run from SRAM on the SoC. I have pushed a branch here [1] based on v3.18-rc6 with all required patches so that the higher level plan for these patches can be seen.
