Move reg_save[] into CONFIG_PM_SLEEP dependency block as it is used only
by suspend and resume functions.
This fixes the warning on CONFIG_PM_SLEEP=n:

The sysreg (system register) generates control signals for various blocks
like disp1blk, i2c, mipi, usb etc. However, it gets disabled as an unused
clock at boot-up. This can lead to failures in operation of above blocks,
because they can not be configured properly if this clock is disabled.

This patch adjusts the refcount in the walk of the interrupt tree.
When a match is found, there is no need to increase the refcount
on 'out_irq->np' as 'newpar' is already holding a ref. The refcount
balance between 'ipar' and 'newpar' is maintained in the skiplevel:
goto label.
This patch also removes the usage of the device_node variable 'old'
which seems useless after the latest changes.

Thierry Reding confirmed this commit was not needed after all:
"We ended up merging a different address representation for Tegra PCIe
and I've confirmed that reverting this commit doesn't cause any obvious
regressions. I think all other drivers in drivers/pci/host ended up
copying what we did on Tegra, so I wouldn't expect any other breakage
either."
There doesn't appear to be a simple way to support both behaviours, so
reverting this as nothing should be depending on the new behaviour.

When using the CLP interface to enable or disable a pci device a
valid function handle needs to be delivered. So far our assumption
was that we always have an up-to-date version of the function handle
(since it doesn't change when the device is in use). This assumption
is incorrect if the pci device is enabled or disabled outside of our
control. When we are notified about such a change we already receive
the new function handle. Just use it.

recvmsg handler in net/rose/af_rose.c performs size-check ->msg_namelen.
After commit f3d3342602f8bcbf37d7c46641cb9bca7618eb1c
(net: rework recvmsg handler msg_name and msg_namelen logic), we now
always take the else branch due to namelen being initialized to 0.
Digging in netdev-vger-cvs git repo shows that msg_namelen was
initialized with a fixed-size since at least 1995, so the else branch
was never taken.

The sizes chosen for the metadata and grant_copy_op arrays on the guest
receive size are wrong;
- The meta array is needlessly twice the ring size, when we only ever
consume a single array element per RX ring slot
- The grant_copy_op array is way too small. It's sized based on a bogus
assumption: that at most two copy ops will be used per ring slot. This
may have been true at some point in the past but it's clear from looking
at start_new_rx_buffer() that a new ring slot is only consumed if a frag
would overflow the current slot (plus some other conditions) so the actual
limit is MAX_SKB_FRAGS grant_copy_ops per ring slot.
This patch fixes those two sizing issues and, because grant_copy_ops grows
so much, it pulls it out into a separate chunk of vmalloc()ed memory.

A deadlock might occur if name table is withdrawn in socket release
routine, and while packets are still being received from bearer.
CPU0 CPU1
T0: recv_msg() release()
T1: tipc_recv_msg() tipc_withdraw()
T2: [grab node lock] [grab port lock]
T3: tipc_link_wakeup_ports() tipc_nametbl_withdraw()
T4: [grab port lock]* named_cluster_distribute()
T5: wakeupdispatch() tipc_link_send()
T6: [grab node lock]*
The opposite order of holding port lock and node lock on above two
different paths may result in a deadlock. If socket lock instead of
port lock is used to protect port instance in tipc_withdraw(), the
reverse order of holding port lock and node lock will be eliminated,
as a result, the deadlock is killed as well.

Commit 5c0484e25ec0 ('powerpc: Endian safe trampoline') resulted in
losing proper alignment of the spinlock variables used when booting
secondary CPUs, causing some quite odd issues with failing to boot on
PA Semi-based systems.
This showed itself on ppc64_defconfig, but not on pasemi_defconfig,
so it had gone unnoticed when I initially tested the LE patch set.
Fix is to add explicit alignment instead of relying on good luck. :)

The powerpc 64-bit __copy_tofrom_user() function uses shifts to handle

big-endian systems: On little-endian systems, they must shift in the
opposite direction.
This commit relies on the C preprocessor to insert the correct shifts
into the assembly code.

In EXCEPTION_PROLOG_COMMON() we check to see if the stack pointer (r1)
is valid when coming from the kernel. If it's not valid, we die but
with a nice oops message.
Currently we allocate a stack frame (subtract INT_FRAME_SIZE) before we
check to see if the stack pointer is negative. Unfortunately, this
won't detect a bad stack where r1 is less than INT_FRAME_SIZE.
This patch fixes the check to compare the modified r1 with
-INT_FRAME_SIZE. With this, bad kernel stack pointers (including NULL
pointers) are correctly detected again.
Kudos to Paulus for finding this.

It turns out that some BIOSes don't report wakeup GPEs through
_PRW, but use them for signaling wakeup anyway, which causes GPE
storms to occur on some systems after resume from system suspend.
This issue has been uncovered by commit d2e5f0c16ad6 (ACPI / PCI:
Rework the setup and cleanup of device wakeup) during the 3.9
development cycle.
Work around the problem by installing wakeup notify handlers for all
PCI devices with ACPI support (i.e. having ACPI companions) regardless
of whether or not the BIOS reports ACPI wakeup support for them. The
presence of the wakeup notify handlers alone is not harmful in any
way if there are no events for them to handle (they are simply never
executed then), but on some systems they are needed to take care of
spurious events.

The definition of virt_addr_valid is that virt_addr_valid should
return true if and only if virt_to_page returns a valid pointer.
The current definition of virt_addr_valid only checks against the
virtual address range. There's no guarantee that just because a
virtual address falls bewteen PAGE_OFFSET and high_memory the
associated physical memory has a valid backing struct page. Follow
the example of other architectures and convert to pfn_valid to
verify that the virtual address is actually valid. The check for
an address between PAGE_OFFSET and high_memory is still necessary
as vmalloc/highmem addresses are not valid with virt_to_page.

When given a compound high page, __flush_dcache_page will only flush
the first page of the compound page repeatedly rather than the entire
set of constituent pages.
This error was introduced by:
0b19f93 ARM: mm: Add support for flushing HugeTLB pages.
This patch corrects the logic such that all constituent pages are now
flushed.

The clockevents code was being told that the footbridge clock event
device ticks at 16x the rate which it actually does. This leads to
timekeeping problems since it allows the clocksource to wrap before
the kernel notices. Fix this by using the correct clock.

Included changes:
- reset netfilter-bridge state when removing the batman-adv
header from an incoming packet. This prevents netfilter
bridge from being fooled when the same packet enters a
bridge twice (or more): the first time within the
batman-adv header and the second time without.
- adjust the packet layout to prevent any architecture from
adding padding bytes. All the structs sent over the wire
now have size multiple of 4bytes (unless pack(2) is used).
- fix access to the inner vlan_eth header when reading the
VID in the rx path.

====================
Netfilter/IPVS fixes for net
This patchset contains four nf_tables fixes, one IPVS fix due to
missing updates in the interaction with the new sedadj conntrack
extension that was added to support the netfilter synproxy code,
and a couple of one-liners to fix netnamespace netfilter issues.
More specifically, they are:
* Fix ipv6_find_hdr() call without offset being explicitly initialized
in nft_exthdr, as required by that function, from Daniel Borkmann.
* Fix oops in nfnetlink_log when using netns and unloading the kernel
module, from Gao feng.
* Fix BUG_ON in nf_ct_timestamp extension after netns is destroyed,
from Helmut Schaa.
* Fix crash in IPVS due to missing sequence adjustment extension being
allocated in the conntrack, from Jesper Dangaard Brouer.
* Add bugtrap to spot a warning in case you deference sequence adjustment
conntrack area when not available, this should help to catch similar
invalid dereferences in the Netfilter tree, also from Jesper.
* Fix incomplete dumping of sets in nf_tables when retrieving by family,
from me.
* Fix oops when updating the table state (dormant <-> active) and having
user (not base ) chains, from me.
* Fix wrong validation in set element data that results in returning
-EINVAL when using the nf_tables dictionary feature with mappings,
also from me.
We don't usually have this amount of fixes by this time (as we're already
in -rc5 of the development cycle), although half of them are related to
nf_tables which is a relatively new thing, and I also believe that holidays
have also delayed the flight of bugfixes to mainstream a bit.

From Simon Horman:
Second Round of Renesas ARM based SoC Fixes for v3.13
* r8a7790 (R-Car H2) based Lager board
- Correct SHDI resource sizes
This bug has been present since sdhi resources were added to the r8a7790 by

After commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051
"ARM: pxa: delete the custom GPIO header" a compilation
error was introduced in the PXA25x gadget driver.
An attempt to fix the problem was made in
commit b144e4ab1ef130e8bf30bcd3e529b7f35112c503
"usb: gadget: fix pxa25x compilation problems"
by explictly stating the driver needs the <mach/hardware.h>
header, which solved the compilation for a few boards,
such as the pxa255-idp and its defconfig.
However the Lubbock board has this special clause in
drivers/usb/gadget/pxa25x_udc.c:
This include file has an implicit dependency on
<mach/irqs.h> having been included before <mach/lubbock.h>
was included.
Before commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051
"ARM: pxa: delete the custom GPIO header" this implicit
dependency for the pxa25x_udc compile on the Lubbock was
satisfied by <linux/gpio.h> implicitly including
<mach/gpio.h> which was in turn including <mach/irqs.h>,
apart from the earlier added <mach/hardware.h>.
Fix this by having the PXA25x <mach/lubbock.h> explicitly
include <mach/irqs.h>.

This patch fixes dictionary mappings, eg.
add rule ip filter input meta dnat set tcp dport map { 22 => 1.1.1.1, 23 => 2.2.2.2 }
The kernel was returning -EINVAL in nft_validate_data_load() since
the type of the set element data that is passed was the real userspace
datatype instead of NFT_DATA_VALUE.

When batadv_get_vid() is invoked in interface_rx() the
batman-adv header has already been removed, therefore
the header_len argument has to be 0.

If an interface enslaved into batman-adv is a bridge (or a
virtual interface built on top of a bridge) the nf_bridge
member of the skbs reaching the soft-interface is filled
with the state about "netfilter bridge" operations.
Then, if one of such skbs is locally delivered, the nf_bridge
member should be cleaned up to avoid that the old state
could mess up with other "netfilter bridge" operations when
entering a second bridge.
This is needed because batman-adv is an encapsulation
protocol.
However at the moment skb->nf_bridge is not released at all
leading to bogus "netfilter bridge" behaviours.
Fix this by cleaning the netfilter state of the skb before
it gets delivered to the upper layer in interface_rx().

struct batadv_icmp_header currently has a size of 17, which
will be padded to 20 on some architectures. Fix this by
unrolling the header into the parent structures.
Moreover keep the ICMP parsing functions as generic as they
are now by using a stub icmp_header struct during packet
parsing.
