Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm

Pull ARM fixes from Russell King:
 "A range of ARM fixes.  Biggest change is the stage-2 attributes used
  for for hyp mode which were wrong.  I've killed some bits in a couple
  of DT files which turned out not to be required, and a few other
  fixes.

  One fix touches code outside of arch/arm, which is related to sorting
  out the DMA masks correctly.  There is a long standing issue with the
  conversion from PFNs to addresses where people assume that shifting an
  unsigned long left by PAGE_SHIFT results in a correct address.  This
  is not the case with C: the integer promotion happens at assignment
  after evaluation.  This fixes the recently introduced dma_max_pfn()
  function, but there's a number of other places where we try this
  directly on an unsigned long in the mm code"

* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  ARM: 7957/1: add DSB after icache flush in __flush_icache_all()
  Fix uses of dma_max_pfn() when converting to a limiting address
  ARM: 7955/1: spinlock: ensure we have a compiler barrier before sev
  ARM: 7953/1: mm: ensure TLB invalidation is complete before enabling MMU
  ARM: 7952/1: mm: Fix the memblock allocation for LPAE machines
  ARM: 7950/1: mm: Fix stage-2 device memory attributes
  ARM: dts: fix spdif pinmux configuration
