2014-11-17ARM: 8195/1: vfp: Bounce undefined instructions in vectored modeStepan Moskovchenko
Certain ARM CPU implementations (e.g. Cortex-A15) may not raise a floating- point exception whenever deprecated short-vector VFP instructions are executed.

2014-11-17ARM: tegra: Re-add removed SoC id macro to tegra_resume()Dmitry Osipenko
Commit d127e9c ("ARM: tegra: make tegra_resume can work with current and later chips") removed tegra_get_soc_id macro leaving used cpu register corrupted after branching to v7_invalidate_l1() and as result causing execution of unintended code on tegra20. Possibly it was expected that r6 would be SoC id func argument since common cpu reset handler is setting r6 before branching to tegra_resume(), but neither tegra20_lp1_reset() nor tegra30_lp1_reset() aren't setting r6 register before jumping to resume function. Fix it by re-adding macro.

2014-11-17ARM: shmobile: Add early debugging support using SCIF(A)Geert Uytterhoeven
Add serial port debug macros for the SCIF(A) serial ports. This includes all supported shmobile SoCs, except for EMEV2. The configuration logic (both Kconfig and #ifdef) is more complicated than one would expect, for several reasons: 1. Not all SoCs have the same serial devices, and they're not always at the same addresses. 2. There are two different types: SCIF and SCIFA. Fortunately they can easily be distinguished by physical address. 3. Not all boards use the same serial port for the console. The defaults correspond to the boards that are supported in mainline. If you want to use a different serial port, just change the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt. 4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END = 0xff000000, and must not conflict with the 2 MiB reserved region at PCI_IO_VIRT_BASE = 0xfee00000. - On SoCs not using the legacy machine_desc.map_io(), debug_ll_io_init() is called by the ARM core code. - On SoCs using the legacy machine_desc.map_io(), debug_ll_io_init() must be called explicitly. Calls are added for r8a7740, r8a7779, sh7372, and sh73a0. This was derived from the r8a7790 version by Laurent Pinchart.
