At the end of the boot process, the clock framework might disable
required main PLL's. So far, this was no issue since drivers
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.
With this patch, we make sure that the main system clock and the
DDR clock are initially enabled and are kept enabled.

- 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

ocfs2: o2net: set tcp user timeout to max value
When tcp retransmit timeout(15mins), the connection will be closed.
Pending messages may be lost during this time. So we set tcp user
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
heartbeat will timeout and it will be evicted, if disk heartbeat not
timeout and connection idle for a long time, then this means the cluster
enters split-brain state, since fence can't happen, we'd better keep the
connection and wait network recover.

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.

kexec: create a new config option CONFIG_KEXEC_FILE for new syscall
Currently new system call kexec_file_load() and all the associated code
compiles if CONFIG_KEXEC=y. But new syscall also compiles purgatory
code which currently uses gcc option -mcmodel=large. This option seems
to be available only gcc 4.4 onwards.
Hiding new functionality behind a new config option will not break
existing users of old gcc. Those who wish to enable new functionality
will require new gcc. Having said that, I am trying to figure out how
can I move away from using -mcmodel=large but that can take a while.
I think there are other advantages of introducing this new config
option. As this option will be enabled only on x86_64, other arches
don't have to compile generic kexec code which will never be used. This
new code selects CRYPTO=y and CRYPTO_SHA256=y. And all other arches had
to do this for CONFIG_KEXEC. Now with introduction of new config
option, we can remove crypto dependency from other arches.
Now CONFIG_KEXEC_FILE is available only on x86_64. So whereever I had
CONFIG_X86_64 defined, I got rid of that.
For CONFIG_KEXEC_FILE, instead of doing select CRYPTO=y, I changed it to
"depends on CRYPTO=y". This should be safer as "select" is not
recursive.

x86,mm: fix pte_special versus pte_numa
Sasha Levin has shown oopses on
ffffea0003480048 and
ffffea0003480008 at
mm/memory.c:1132, running Trinity on different 3.16-rc-next kernels:
where zap_pte_range() checks page->mapping to see if PageAnon(page).
Those addresses fit struct pages for pfns d2001 and d2000, and in each
dump a register or a stack slot showed
d2001730 or
d2000730: pte flags
0x730 are PCD ACCESSED PROTNONE SPECIAL IOMAP; and Sasha's e820 map has
a hole between
cfffffff and
100000000, which would need special access.
Commit
c46a7c817e66 ("x86: define _PAGE_NUMA by reusing software bits on
the PMD and PTE levels") has broken vm_normal_page(): a PROTNONE SPECIAL
pte no longer passes the pte_special() test, so zap_pte_range() goes on
to try to access a non-existent struct page.
Fix this by refining pte_special() (SPECIAL with PRESENT or PROTNONE) to
complement pte_numa() (SPECIAL with neither PRESENT nor PROTNONE). A
hint that this was a problem was that
c46a7c817e66 added pte_numa() test
to vm_normal_page(), and moved its is_zero_pfn() test from slow to fast
path: This was papering over a pte_special() snag when the zero page was
encountered during zap. This patch reverts vm_normal_page() to how it
was before, relying on pte_special().
It still appears that this patch may be incomplete: aren't there other
places which need to be handling PROTNONE along with PRESENT? For
example, pte_mknuma() clears _PAGE_PRESENT and sets _PAGE_NUMA, but on a
PROT_NONE area, that would make it pte_special(). This is side-stepped
by the fact that NUMA hinting faults skipped PROT_NONE VMAs and there
are no grounds where a NUMA hinting fault on a PROT_NONE VMA would be
interesting.

Merge tag 'usb-3.17-rc3' of git://git./linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH:
"Here are a bunch of fixes for the USB drivers for 3.17-rc3.
Also in here is the movement of the usbip driver out of staging, into
the "real" part of the kernel, it had to wait until after -rc1 to
handle the merge issues involved between the USB and staging trees.
The code is identical, just file movements there.
The USB fixes are all over the place, new device ids, xhci fixes for
reported issues and the usual gadget driver fixes as well. All have
been in linux-next for a while now"
