2015-12-15ARM: 8471/1: need to save/restore arm register(r11) when it is corruptedAnson Huang
In cpu_v7_do_suspend routine, r11 is used while it is NOT saved/restored, different compiler may have different usage of ARM general registers, so it may cause issues during calling cpu_v7_do_suspend. We meet kernel fault occurs when using GCC 4.8.3, r11 contains valid value before calling into cpu_v7_do_suspend, but when returned from this routine, r11 is corrupted and lead to kernel fault. Doing save/restore for those corrupted registers is a must in assemble code.

2015-12-15ARM: fix uaccess_with_memcpy() with SW_DOMAIN_PANRussell King
The uaccess_with_memcpy() code is currently incompatible with the SW PAN code: it takes locks within the region that we've changed the DACR, potentially sleeping as a result. As we do not save and restore the DACR across co-operative sleep events, can lead to an incorrect DACR value later in this code path.

2015-12-15ARM: realview: add an DT SMP boot methodLinus Walleij
This adds an SMP boot method for the ARM RealView reference designs. We also select HAVE_SMP by default and make it use SMP_ON_UP so we only need to support one single kernel across the RealView reference designs when using DT. The RealViews need to have the SCU (Snoop Control Unit) activated on boot, and this is now done by looking up its address from the device tree and initializing it and counting the available cores. The RealViews boot by using a magic address register in the system controller (SYS_FLAGS) to store the boot address, the ROM will then read this register to the PC when the CPUs are taken out of WFI. This code uses a handle to the syscon regmap to access this register. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2015-12-15ARM: realview: remove private barrier implementationArnd Bergmann
The realview barrier implementation tries to avoid calling outer_sync in order to not lock up as a result of a bug in the l220 cache controller. This gets in the way of the multiplatform support, but we can still remove it if we make sure that the outer_sync function never gets called, by replacing the function pointer with NULL, right after initialization.

2015-12-15ARM: no longer force unbuffered DMA for realviewArnd Bergmann
Commit 42c4dafe803dca ("ARM: 6202/1: Do not ARM_DMA_MEM_BUFFERABLE on RealView boards with L210/L220") changed the generic setting for ARM_DMA_MEM_BUFFERABLE to be disabled on any Realview kernel that includes support for any of the ARM11 variations. Doing this was required to allow doing DMA without a lockup in the l2x0 cache controller on the Realview platform. Unfortunately, in a kernel that also contains support for any ARMv7 based machine, the same change makes it impossible to do DMA on ARMv7, which gets in the way of enabling multiplatform support on Realview. As confirmed by Catalin Marinas and Linus Walleij, the current code for Realview that we have in the kernel does not actually perform any DMA, and this is unlikely to change in the future. Therefore we can revert 42c4dafe803dca without introducing regressions, but we must never start using DMA on this platform in the future.

2015-12-15ARM: realview: remove sparsemem hackArnd Bergmann
The realview-pbx platform has an elaborate way of avoiding the use of highmem by redefining its phys_to_virt function. In practice this doesn't help all that much, and it gets in the way of doing multiplatform builds for realview. This removes the feature and kills off the mach/memory.h file for realview. We also lose the ability to do sparsemem with this patch, but that should be put back into place for generic multiplatform configurations, to save a little memory on PBX.
