Subject: [GIT PULL] Last minute bug fix for Exynos platform

Hi Linus,

This bug fix has been brewing for a while. I hate sending it to you so
late, but I only got confirmation that it solves the problem this past
weekend. The diff looks big for a bug fix, but the majority of it is
only executed in the Exynos quirk case. Unfortunately it required
splitting early_init_dt_scan() in two and adding quirk handling in the
middle of it on ARM.

If you're not happy pulling at this late stage then I'll add it to my
v3.17 merge queue and ask Greg to pull it into stable.

g.

  arm: Add devicetree fixup machine function (2014-07-29 21:26:49 -0600)

----------------------------------------------------------------
Device tree Exynos bug fix for v3.16-rc7

Exynos has buggy firmware that puts bad data into the memory node. Commit
1c2f87c2 (ARM: Get rid of meminfo) exposed the bug by dropping the artificial
upper bound on the number of memory banks that can be added. Exynos fails to
boot after that commit. This branch fixes it by splitting the early DT parse
function and inserting a fixup hook. Exynos uses the hook to correct the DT
before parsing memory regions.
