      [ARM] 4415/1: AML5900: fix sparse warnings from map_io · e078761a
      Ben Dooks authored
      The map_io function does not need to be exported
      from this file, and therefore should be declared
      static.

      [ARM] 4412/1: S3C2412: reset errata fix · eca8c242
      Ben Dooks authored
      The S3C2412 has an reset-errata where the clock
      may cause a glitch switching back to EXTCLK. We
      force a switch to EXTCLK before writing the
      reset register to force use of the CLKCON sync
      logic to properly switch.
      
      Fix problem reported by Matthieu Castet.

      [ARM] Fix stacktrace FP range checking · 5b10c8e4
      Russell King authored
      Fix an oops in the stacktrace code, caused by improper range checking.
      We subtract 12 off 'fp' before testing to see if it's below the low
      bound.  However, if 'fp' were zero before, it becomes a very large
      positive number, causing this test to succeed where it should fail.
