A bug was introduced in the merge commit b633353115e3 ("Merge
git://git.kernel.org/pub/scm/linux/kernel/git/davem/net")
The generic marvell_config_init (and therefore marvell_of_reg_init) is
not called anymore for the Marvell 88E1510 (in net-next).
This patch calls marvell_config_init and moves the specific init
function for the 88E1510 below the marvell_config_init function to avoid
adding a function predeclaration.

Nik pointed that the VRF driver should be using skb_header_pointer
instead of accessing skb->data and bits beyond directly which can
be garbage.

net: dsa: add port VLAN dump operation
The VLAN GetNext approach is specific to some switches and thus hard to
implement for others. This patchset replaces it with a simpler port VLAN dump
operation, similar to the corresponding FDB operation.
The mv88e6xxx driver is the only one currently affected by the change.
The documentation is updated accordingly.
Note: this patchset uses http://www.spinics.net/lists/kernel/msg2186705.html

The VLAN GetNext operation is specific to some switches, and thus can be
complicated to implement for some drivers.
Remove the support for the vlan_getnext/port_pvid_get approach in favor
of the generic and simpler port_vlan_dump function.

Similar to port_fdb_dump, add a port_vlan_dump function to DSA drivers
which gets passed the switchdev VLAN object and callback.
This function, if implemented, takes precedence over the soon legacy
vlan_getnext/port_pvid_get approach.

vxlan: consolidate rx handling
Currently, vxlan_rcv is just called at the end of vxlan_udp_encap_recv,
continuing the rx processing where vxlan_udp_encap_recv left it. There's no
clear border between those two functions. This patchset moves
vxlan_udp_encap_recv and vxlan_rcv into a single function.
This also allows to do some simplification in error path.
The VXLAN-GPE implementation that will follow up this set can be seen at:

Now when the packet is scrubbed early, the metadata_dst can be assigned to

as the dst will be freed by kfree_skb. It is also not necessary to pass it

Currently tc actions are stored in a per-module hashtable,
therefore are visible to all network namespaces. This is
probably the last part of the tc subsystem which is not
aware of netns now. This patch makes them per-netns,
several tc action API's need to be adjusted for this.
The tc action API code is ugly due to historical reasons,
we need to refactor that code in the future.

We only release the memory of the hashtable itself, not its
entries inside. This is not a problem yet since we only call
it in module release path, and module is refcount'ed by
actions. This would be a problem after we move the per module
hinfo into per netns in the latter patch.

And, the variable 'phys_addr' was defined as "unsigned long" by mistake -- it should

The AMD Family 15h Models 30h-3Fh (Kaveri) BIOS and Kernel Developer's
Guide omitted part of the BIOS IOMMU L2 register setup specification.
Without this setup the IOMMU L2 does not fully respect write permissions
when handling an ATS translation request.
The IOMMU L2 will set PTE dirty bit when handling an ATS translation with
write permission request, even when PTE RW bit is clear. This may occur by
direct translation (which would cause a PPR) or by prefetch request from
the ATC.
This is observed in practice when the IOMMU L2 modifies a PTE which maps a
pagecache page. The ext4 filesystem driver BUGs when asked to writeback
these (non-modified) pages.
Enable ATS write permission check in the Kaveri IOMMU L2 if BIOS has not.

The setup code for the performance counters in the AMD IOMMU driver
tests whether the counters can be written. It tests to setup a counter
for device 00:00.0, which fails on systems where this particular device
is not covered by the IOMMU.
Fix this by not relying on device 00:00.0 but only on the IOMMU being
present.

The R-Car GPIO driver handles Runtime PM for requested GPIOs only.
When using a GPIO purely as an interrupt source, no Runtime PM handling
is done, and the GPIO module's clock may not be enabled.
To fix this:
- Add .irq_request_resources() and .irq_release_resources() callbacks
to handle Runtime PM when an interrupt is requested,
- Add irq_bus_lock() and sync_unlock() callbacks to handle Runtime PM
when e.g. disabling/enabling an interrupt, or configuring the
interrupt type.

When a directory is deleted, we don't take too much care about killing off
all the dirents that belong to it — on the basis that on remount, the scan
will conclude that the directory is dead anyway.
This doesn't work though, when the deleted directory contained a child
directory which was moved *out*. In the early stages of the fs build
we can then end up with an apparent hard link, with the child directory
appearing both in its true location, and as a child of the original
directory which are this stage of the mount process we don't *yet* know
is defunct.
To resolve this, take out the early special-casing of the "directories
shall not have hard links" rule in jffs2_build_inode_pass1(), and let the
normal nlink processing happen for directories as well as other inodes.
Then later in the build process we can set ic->pino_nlink to the parent
inode#, as is required for directories during normal operaton, instead
of the nlink. And complain only *then* about hard links which are still
in evidence even after killing off all the unreachable paths.

This reverts commit 5ffd3412ae55
("jffs2: Fix lock acquisition order bug in jffs2_write_begin").
The commit modified jffs2_write_begin() to remove a deadlock with
jffs2_garbage_collect_live(), but this introduced new deadlocks found
by multiple users. page_lock() actually has to be called before
mutex_lock(&c->alloc_sem) or mutex_lock(&f->sem) because
jffs2_write_end() and jffs2_readpage() are called with the page locked,
and they acquire c->alloc_sem and f->sem, resp.
In other words, the lock order in jffs2_write_begin() was correct, and
it is the jffs2_garbage_collect_live() path that has to be changed.
Revert the commit to get rid of the new deadlocks, and to clear the way
for a better fix of the original deadlock.

Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.

New generation devices have firmware which has more than 256 flowrings.
E.g. following debugging message comes from 14e4:4365 BCM4366:
[ 194.606245] brcmfmac: brcmf_pcie_init_ringbuffers Nr of flowrings is 264
At various code places (related to flowrings) we were using u8 which
could lead to storing wrong number or infinite loops when indexing with
this type. This issue was quite easy to spot in brcmf_flowring_detach
where it led to infinite loop e.g. on failed initialization.
This patch switches code to proper types and increases the maximum
number of supported flowrings to 512.
Originally this change was sent in September 2015, but back it was
causing a regression on BCM43602 resulting in:
Unable to handle kernel NULL pointer dereference at virtual address ...
The reason for this regression was missing update (s/u8/u16) of struct
brcmf_flowring_ring. This problem was handled in 9f64df9 ("brcmfmac: Fix
bug in flowring management."). Starting with that it's safe to apply
this original patch as it doesn't cause a regression anymore.
This patch fixes an infinite loop on BCM4366 which is supported since
4.4 so it makes sense to apply it to stable 4.4+.
