This hooks dtc into Kbuild's dependency system. Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous lack of this feature recently caused me to have very confusing "git bisect" results. For ARM, it's obvious what to add to $(targets). I'm not familiar enough with other architectures to know what to add there. Powerpc appears to already add various .dtb files into $(targets), but the other archs may need something added to $(targets) to work.

The existing gpio_to_irq() implementation on sa1100 only translates validly for internal GPIOs. Since this sub-arch enables GPIOLIB support, this results in buggy translations for non-internal GPIOs. Get rid of the private gpio_to_irq() implementation, replacing it with the .to_irq method in the sa1100 gpio chip instead.

Several platforms are now using the memblock_alloc+memblock_free+ memblock_remove trick to obtain memory which won't be mapped in the kernel's page tables. Most platforms do this (correctly) in the ->reserve callback. However, OMAP has started to call these functions outside of this callback, and this is extremely unsafe - memory will not be unmapped, and could well be given out after memblock is no longer responsible for its management. So, provide arm_memblock_steal() to perform this function, and ensure that it panic()s if it is used inappropriately. Convert everyone over, including OMAP. As a result, OMAP with OMAP4_ERRATA_I688 enabled will panic on boot with this change. Mark this option as BROKEN and make it depend on BROKEN. OMAP needs to be fixed, or 137d105d (ARM: OMAP4: Fix errata i688 with MPU interconnect barriers.) reverted until such time it can be fixed correctly.

This patch contains r8a7779 SMP support V3 - now including CPU hotplug offine and online support. The r8a7779 power domain code is tied together with SMP glue code which allows us to control the power domains via CPU hotplug. At this point the kernel boots with the 4 Cortex-A9 cores in SMP mode and all CPU cores except CPU0 can be hotplugged. The code in platsmp.c is quite far from pretty, but it is kept like that intentionally to avoid creating layers of code that will go away in the near future anyway. The code needs to be updated when some per-SoC handling code will be added to the ARM architecture, see the following patch for more information: "[RFC PATCH 0/3] Per SoC descriptor" Signed-off-by: NMagnus Damm <damm@opensource.se> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Randomization of PIE load address is hard coded in binfmt_elf.c for X86 and ARM. Create a new Kconfig variable (CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE) for this and use it instead. Thus architecture specific policy is pushed out of the generic binfmt_elf.c and into the architecture Kconfig files. X86 and ARM Kconfigs are modified to select the new variable so there is no change in behavior. A follow on patch will select it for MIPS too.

This patch converts ARM's architecture-specific inlined 'pcibios_set_master()' routine to a non-inlined function. This will allow follow on patches to create a generic 'pcibios_set_master()' function using the '__weak' attribute which can be used by all architectures as a default which, if necessary, can then be over- ridden by architecture-specific code. Converting 'pci_bios_set_master()' to a non-inlined function will allow ARM's 'pcibios_set_master()' implementation to remain architecture- specific after the generic version is introduced and thus, not change current behavior. Note that ARM also has a non-inlined 'pcibios_set_master()' that is used if CONFIG_PCI_HOST_ITE8152 is defined. This patch does not change any behavior here either. No functional change.
