requested clocks, which are descended of the main PLL's (e.g.
pll1_pfd1, which provides the system clock).

To archive the full 500MHz system clock, DDR clock need to be a
descendant of PLL2 rather than PLL1 (DDRC_CLK_SEL set to 0). The
bootloader sets up the clocks accordingly before making use of
DDR at all. However, in Linux, there is no driver using PLL2,
which lead to PLL2 being disabled by the clock framework.

  The delta is a largeish negative delta, due to revert of SMP support
  for Broadcom's STB SoC -- it was accidentally merged before some
  issues had been addressed, so they will make a new attempt for 3.18.
  I didn't see a need for a full revert of the whole platform due to
  this, we're keeping the rest enabled.

  The rest is mostly:

   - a handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
   - some MTD/NAND fixes for OMAP
   - minor DT fixes for shmobile
   - warning fix for UP builds on vexpress/spc

  There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
  so it can boot.  Drivers and the rest had landed for 3.17, and it's

timeout to override the retransmit timeout to the max value.  This is OK
for ocfs2 since we have disk heartbeat, if peer crash, the disk

ocfs2: o2net: don't shutdown connection when idle timeout

This patch series is to fix a possible message lost bug in ocfs2 when
network go bad.  This bug will cause ocfs2 hung forever even network
become good again.

The messages may lost in this case.  After the tcp connection is
established between two nodes, an idle timer will be set to check its
state periodically, if no messages are received during this time, idle
timer will timeout, it will shutdown the connection and try to
reconnect, so pending messages in tcp queues will be lost.  This
messages may be from dlm.  Dlm may get hung in this case.  This may
cause the whole ocfs2 cluster hung.

This is very possible to happen when network state goes bad.  Do the
reconnect is useless, it will fail if network state is still bad.  Just
waiting there for network recovering may be a good idea, it will not
lost messages and some node will be fenced until cluster goes into
split-brain state, for this case, Tcp user timeout is used to override
the tcp retransmit timeout.  It will timeout after 25 days, user should
have notice this through the provided log and fix the network, if they
don't, ocfs2 will fall back to original reconnect way.

This patch (of 3):

Some messages in the tcp queue maybe lost if we shutdown the connection
and reconnect when idle timeout.  If packets lost and reconnect success,
then the ocfs2 cluster maybe hung.

To fix this, we can leave the connection there and do the fence decision
when idle timeout, if network recover before fence dicision is made, the
connection survive without lost any messages.

This bug can be saw when network state go bad.  It may cause ocfs2 hung
forever if some packets lost.  With this fix, ocfs2 will recover from
hung if network becomes good again.
