powerpc/powernv: I/O and memory alignment for P2P bridges
The patch implements ppc_md.pcibios_window_alignment for powernv
platform so that the resource reassignment in PCI core will be
done according to the I/O and memory alignment returned from
powernv platform. The alignments returned from powernv platform
is closely depending on the scheme for PE segmenting. Besides,
the patch isn't useful for now, but the subsequent patches will
be working based on it.

This patch implements pcibios_window_alignment() so powerpc platforms can
force P2P bridge windows to be at larger alignments than the PCI spec
requires.
The original idea comes from Ram Pai. This patch puts the chunk of
code for calculating the minimal alignment of memory window into a
separate inline function.
PCI: Align P2P windows using pcibios_window_alignment()
This patch changes pbus_size_io() and pbus_size_mem() to do window (I/O,
memory and prefetchable memory) reassignment based on the minimal
alignments for the P2P bridge, which was retrieved by window_alignment().
This patch implements a weak function to return the default I/O or memory
window alignment for a P2P bridge. By default, I/O windows are aligned to
4KiB or 1KiB and memory windows are aligned to 4MiB. Some platforms, e.g.,
powernv, have special alignment requirements and can override
pcibios_window_alignment().

ARM: PRIMA2: delete redundant codes to restore LATCHED when timer resumes
The only way to write LATCHED registers to write LATCH_BIT to LATCH register,
that will latch COUNTER into LATCHED.e.g.
writel_relaxed(SIRFSOC_TIMER_LATCH_BIT, sirfsoc_timer_base +
SIRFSOC_TIMER_LATCH);
Writing values to LATCHED registers directly is useless at all.

ceph: simplify+fix atomic_open
The initial ->atomic_open op was carried over from the old intent code,
which was incomplete and didn't really work. Replace it with a fresh
method. In particular:
* always attempt to do an atomic open+lookup, both for the create case
and for lookups of existing files.
* fix symlink handling by returning 1 to the VFS so that we can follow
the link to its destination. This fixes a longstanding ceph bug (#2392).

Pull MIPS updates from Ralf Baechle:
"The lion share of this pull request are fixes for clk-related breakage
caused by other changes during this merge window. For some platforms
the fix was as simple as selecting HAVE_CLK, for others like the
Loongson 2 significant restructuring was required.
The remainder are changes required to get the Lantiq code to work
again."
