Merge branch 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King: "Three relatively small fixes for ARM: - Roger noticed that dma_max_pfn() was calculating the upper limit wrongly, by adding the PFN offset of memory twice. - A fix from Robin to correct parsing of MPIDR values when the address size is larger than one BE32 unit. - A fix from Srinivas to ensure that we do not rely on the boot loader (or previous Linux kernel) setting the translation table base register a certain way in the decompressor, which can lead to crashes" * 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: 8618/1: decompressor: reset ttbcr fields to use TTBR0 on ARMv7 ARM: 8617/1: dma: fix dma_max_pfn() ARM: 8616/1: dt: Respect property size when parsing CPUs
