to avoid padding on any architecture.

2f7a318219 batman-adv: fix size of batadv_bla_claim_dst
Since this is a mac address and always 48 bit, and we can assume that
it is always aligned to 2-byte boundaries, add a pack(2) pragma.

27a417e6ba batman-adv: fix size of batadv_icmp_header
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.

a40d9b075c batman-adv: fix header alignment by unrolling batadv_header
The size of the batadv_header of 3 is problematic on some architectures
which automatically pad all structures to a 32 bit boundary. To not lose
performance by packing this struct, better embed it into the various
host structures.

46b76e0b8b batman-adv: fix alignment for batadv_coded_packet
The compiler may decide to pad the structure, and then it does not
have the expected size of 46 byte. Fix this by moving it in the
pragma pack(2) part of the code.

750b8de6c4 cifs: We do not drop reference to tlink in CIFSCheckMFSymlink()
When we obtain tcon from cifs_sb, we use cifs_sb_tlink() to first obtain
tlink which also grabs a reference to it. We do not drop this reference
to tlink once we are done with the call.

The patch fixes this issue by instead passing tcon as a parameter and
avoids having to obtain a reference to the tlink. A lookup for the tcon
is already made in the calling functions and this way we avoid having to
re-run the lookup. This is also consistent with the argument list for
other similar calls for M-F symlinks.

We should also return an ENOSYS when we do not find a protocol specific
function to lookup the MF Symlink data.

1a29321ed0 net_sched: act: Dont increment refcnt on replace
This is a bug fix. The existing code tries to kill many
 birds with one stone: Handling binding of actions to
 filters, new actions and replacing of action
 attributes. A simple test case to illustrate:

XXXX
 moja@fe1:~$ sudo tc actions add action drop index 12
 moja@fe1:~$ actions get action gact index 12
 action order 1: gact action drop
  random type none pass val 0
  index 12 ref 1 bind 0
 moja@fe1:~$ sudo tc actions replace action ok index 12
 moja@fe1:~$ actions get action gact index 12
 action order 1: gact action drop
  random type none pass val 0
  index 12 ref 2 bind 0
XXXX

The above shows the refcounf being wrongly incremented on replace.
There are more complex scenarios with binding of actions to filters
that i am leaving out that didnt work as well...

7e367c18c0 ARM: OMAP2+: Fix LCD panel backlight regression for LDP legacy booting
Looks like the LCD panel on LDP has been broken quite a while, and
recently got fixed by commit 0b2aa8bed3 (gpio: twl4030: Fix regression
for twl gpio output). However, there's still an issue left where the panel
backlight does not come on if the LCD drivers are built into the
kernel.

Fix the issue by registering the DPI LCD panel only after the twl4030
GPIO has probed.

b25adce160 ipvs: correct usage/allocation of seqadj ext in ipvs
The IPVS FTP helper ip_vs_ftp could trigger an OOPS in nf_ct_seqadj_set,
after commit 41d73ec053 (netfilter: nf_conntrack: make sequence number
adjustments usuable without NAT).

This is because, the seqadj ext is now allocated dynamically, and the
IPVS code didn't handle this situation.  Fix this in the IPVS nfct
code by invoking the alloc function nfct_seqadj_ext_add().

797f87f83b macvlan: fix netdev feature propagation from lower device
There are inconsistencies wrt. feature propagation/inheritance between
macvlan and the underlying interface.

When a feature is turned off on the real device before a macvlan is
created on top, these will remain enabled on the macvlan device, whereas
turning off the feature on the lower device after macvlan creation the
kernel will propagate the changes to the macvlan.

The second issue is that, when propagating changes from underlying device
to the macvlan interface, macvlan can erronously lose its NETIF_F_LLTX flag,
as features are anded with the underlying device.

However, LLTX should be kept since it has no dependencies on physical
hardware (LLTX is set on macvlan creation regardless of the lower
device properties, see 8ffab51b3d
(macvlan: lockless tx path).

The LLTX flag is now forced regardless of user settings in absence of
layer2 hw acceleration (a6cc0cfa72,
net: Add layer 2 hardware acceleration operations for macvlan devices).

Use netdev_increment_features to rebuild the feature set on capability
changes on either the lower device or on the macvlan interface.

As pointed out by Ben Hutchings, use netdev_update_features on
NETDEV_FEAT_CHANGE event (it calls macvlan_fix_features/netdev_features_change
if needed).

Commit 4dcfa60071 ("ARM: DMA-API: better
handing of DMA masks for coherent allocations") added an additional
check to the coherent DMA mask that results in an error when the mask is
larger than what dma_addr_t can address.

Set the LCDC coherent DMA mask to DMA_BIT_MASK(32) instead of ~0 to fix

6d4c883047 ARM: OMAP2+: hwmod_data: fix missing OMAP_INTC_START in irq data
Commit 7d7e1eb (ARM: OMAP2+: Prepare for irqs.h removal) and commit
ec2c082 (ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ)
updated the way interrupts for OMAP2/3 devices are defined in the
HWMOD data structures to being an index plus a fixed offset (defined
by OMAP_INTC_START).

Couple of irqs in the OMAP2/3 hwmod data were misconfigured completely
as they were missing this OMAP_INTC_START relative offset. Add this
offset back to fix the incorrect irq data for the following modules:
	OMAP2 - GPMC, RNG
	OMAP3 - GPMC, ISP MMU & IVA MMU

With commit '7dedd34: ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with
 DEBUG_LL' we moved from parsing cmdline to identify uart used for earlycon
to using the requsite hwmod CONFIG_DEBUG_OMAPxUARTy FLAGS.

On DRA7 though, we seem to be missing this flag, and atleast on the DRA7 EVM
where we use uart1 for console, boot fails with DEBUG_LL enabled.

6c7bccea39 drm/radeon/pm: move pm handling into the asic specific code
We need more control over the ordering of dpm init with
respect to the rest of the asic.  Specifically, the SMC
has to be initialized before the rlc and cg/pg.  The pm
code currently initializes late in the driver, but we need
it to happen much earlier so move pm handling into the asic
specific callbacks.

This makes dpm more reliable and makes clockgating work
properly on CIK parts and should help on SI parts as well.
