Take struct mlx5_frag_buf out of mlx5_frag_buf_ctrl, as it is not
needed to manage and control the datapath of the fragmented buffers API.
struct mlx5_frag_buf contains control info to manage the allocation
and de-allocation of the fragmented buffer.
Its fields are not relevant for datapath, so here I take them out of the
struct mlx5_frag_buf_ctrl, except for the fragments array itself.
In addition, modified mlx5_fill_fbc to initialise the frags pointers
as well. This implies that the buffer must be allocated before the
function is called.
A set of type-specific *_get_byte_size() functions are replaced by
a generic one.

'default n' is the default value for any bool or tristate Kconfig setting
so there is no need to write it explicitly.
Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not
set' for visible symbols") the Kconfig behavior is the same regardless of
'default n' being present or not:
...
One side effect of (and the main motivation for) this change is making
the following two definitions behave exactly the same:
config FOO
bool
config FOO
bool
default n
With this change, neither of these will generate a
'# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
That might make it clearer to people that a bare 'default n' is
redundant.

rtl_rx() and rtl_tx() are called only if the respective bits are set
in the interrupt status register. Under high load NAPI may not be
able to process all data (work_done == budget) and it will schedule
subsequent calls to the poll callback.
rtl_ack_events() however resets the bits in the interrupt status
register, therefore subsequent calls to rtl8169_poll() won't call
rtl_rx() and rtl_tx() - chip interrupts are still disabled.
Fix this by calling rtl_rx() and rtl_tx() independent of the bits
set in the interrupt status register. Both functions will detect
if there's nothing to do for them.

sk->sk_wmem_queued is used to count the size of chunks in out queue
while sk->sk_wmem_alloc is for counting the size of chunks has been
sent. sctp is increasing both of them before enqueuing the chunks,
and using sk->sk_wmem_alloc to check for writable space.
However, sk_wmem_alloc is also increased by 1 for the skb allocked
for sending in sctp_packet_transmit() but it will not wake up the
waiters when sk_wmem_alloc is decreased in this skb's destructor.
If msg size is equal to sk_sndbuf and sendmsg is waiting for sndbuf,
the check 'msg_len <= sctp_wspace(asoc)' in sctp_wait_for_sndbuf()
will keep waiting if there's a skb allocked in sctp_packet_transmit,
and later even if this skb got freed, the waiting thread will never
get waked up.
This issue has been there since very beginning, so we change to use
sk->sk_wmem_queued to check for writable space as sk_wmem_queued is
not increased for the skb allocked for sending, also as TCP does.
SOCK_SNDBUF_LOCK check is also removed here as it's for tx buf auto
tuning which I will add in another patch.

Now it's confusing that asoc sndbuf_used is doing memory accounting with
SCTP_DATA_SNDSIZE(chunk) + sizeof(sk_buff) + sizeof(sctp_chunk) while sk
sk_wmem_alloc is doing that with skb->truesize + sizeof(sctp_chunk).
It also causes sctp_prsctp_prune to count with a wrong freed memory when
sndbuf_policy is not set.
To make this right and also keep consistent between asoc sndbuf_used, sk
sk_wmem_alloc and sk_wmem_queued, use skb->truesize + sizeof(sctp_chunk)
for them.

This fixes a general protection fault, caused by accessing the contents
of a flip_done completion object that has already been freed. It occurs
due to the preemption of a non-blocking commit worker thread W by
another commit thread X. X continues to clear its atomic state at the
end, destroying the CRTC commit object that W still needs. Switching
back to W and accessing the commit objects then leads to bad results.
Worker W becomes preemptable when waiting for flip_done to complete. At
this point, a frequently occurring commit thread X can take over. Here's
an example where W is a worker thread that flips on both CRTCs, and X
does a legacy cursor update on both CRTCs:
...
1. W does flip work
2. W runs commit_hw_done()
3. W waits for flip_done on CRTC 1
4. > flip_done for CRTC 1 completes
5. W finishes waiting for CRTC 1
6. W waits for flip_done on CRTC 2
7. > Preempted by X
8. > flip_done for CRTC 2 completes
9. X atomic_check: hw_done and flip_done are complete on all CRTCs
10. X updates cursor on both CRTCs
11. X destroys atomic state
12. X done
13. > Switch back to W
14. W waits for flip_done on CRTC 2
15. W raises general protection fault
The error looks like so:
general protection fault: 0000 [#1] PREEMPT SMP PTI

Note that i915 has this issue masked, since hw_done is signaled after
waiting for flip_done. Doing so will block the cursor update from
happening until hw_done is signaled, preventing the cursor commit from
destroying the state.
v2: The reference on the commit object needs to be obtained before
hw_done() is signaled, since that's the point where another commit
is allowed to modify the state. Assuming that the
new_crtc_state->commit object still exists within flip_done() is
incorrect.
Fix by getting a reference in setup_commit(), and releasing it
during default_clear().

Make declaration type determination more robust.
When scripts/kernel-doc is deciding if some kernel-doc notation
contains an enum, a struct, a union, a typedef, or a function,
it does a pattern match on the beginning of the string, looking
for a match with one of "struct", "union", "enum", or "typedef",
and otherwise defaults to a function declaration type.
However, if a function or a function-like macro has a name that
begins with "struct" (e.g., struct_size()), then kernel-doc
incorrectly decides that this is a struct declaration.
Fix this by looking for the declaration type keywords having an
ending word boundary (\b), so that "struct_size" will not match
a struct declaration.

1GbE Intel Wired LAN Driver Updates 2018-10-17
This series adds support for the new igc driver.
The igc driver is the new client driver supporting the Intel I225
Ethernet Controller, which supports 2.5GbE speeds. The reason for
creating a new client driver, instead of adding support for the new
device in e1000e, is that the silicon behaves more like devices
supported in igb driver. It also did not make sense to add a client
part, to the igb driver which supports only 1GbE server parts.
This initial set of patches is designed for basic support (i.e. link and
pass traffic). Follow-on patch series will add more advanced support
like VLAN, Wake-on-LAN, etc..

mlx5-updates-2018-10-17
========================================================================
From Or Gerlitz <ogerlitz@mellanox.com>:
This series from Paul adds support to mlx5 e-switch tc offloading of multiple priorities and chains.
This is made of four building blocks (along with few minor driver refactors):
[1] Split FDB fast path prio to multiple namespaces
Currently the FDB name-space contains two priorities, fast path (p0) and slow path (p1).
The slow path contains the per representor SQ send-to-vport TX rule and the match-all
RX miss rule. As a pre-step to support multi-chains and priorities, we split the FDB fast path
to multiple namespaces (sub namespaces), each with multiple priorities.
[2] E-Switch chains and priorities
A chain is a group of priorities. We use the fdb parallel sub-namespaces to implement chains,
and a flow table for each priority in them.
Because these namespaces are parallel and in series to the slow path
fdb, the chains aren't connected to each other (but to the slow path),
and one must use a explicit goto action to reach a different chain.
Flow tables for the priorities are created on demand and destroyed
once not used.
[3] Add a no-append flow insertion mode, use it for TC offloads
Enhance the driver fs core, such that if a no-append flag is set by the caller,
we add a new FTE, instead of appending the actions of the inserted rule when
the same match already exists.
For encap rules, we defer the HW offloading till we have a valid neighbor. This can
result in the packet hitting a lower priority rule in the HW DP. Use the no-append API
to push these packets to the slow path FDB table, so they go to the TC kernel DP as done
before priorities where supported.
[4] Offloading tc priorities and chains for eswitch flows
Using [1], [2] and [3] above we add the support for offloading both chains
and priorities. To get to a new chain, use the tc goto action. We support
a fixed prio range 1-16, and chains 0-3.

The PCI controller in the Marvell Armada 3720 does not implement a
software-accessible root port PCI bridge configuration space. This
causes a number of problems when using PCIe switches or when the Max
Payload size needs to be aligned between the root complex and the
endpoint.
Implementing an emulated root PCI bridge, like is already done in the
pci-mvebu driver for older Marvell platforms allows to solve those
issues, and also to support features such as ASR, PME, VC, HP.

Commit dc0352ab0b2a0 ("PCI: mvebu: Add PCI Express root complex
capability block") added support for emulating the PCI Express
capability block. As part of this, the pcie_sltcap, pcie_devctl and
pcie_rtctl fields were added to the mvebu_sw_pci_bridge structure, and
used when reading the corresponding PCI Express capability block
registers.
However, those structure members are never set to any value other than
zero. This makes them unneeded because:
- pcie_devctl is used to OR *value, so with pcie_devctl always zero,
it has no effect.
- for pcie_sltcap and pcie_rtstl, the mvebu_sw_pci_bridge_read()
function always returns 0 for registers that are not explicitly
handled.
In preparation for reworking the PCI bridge emulation logic in
pci-mvebu, let's simplify the code by dropping those structure
members.

Some PCI host controllers do not expose a configuration space for the
root port PCI bridge. Due to this, the Marvell Armada 370/38x/XP PCI
controller driver (pci-mvebu) emulates a root port PCI bridge
configuration space, and uses that to (among other things) dynamically
create the memory windows that correspond to the PCI MEM and I/O
regions.
Since we now need to add a very similar logic for the Marvell Armada
37xx PCI controller driver (pci-aardvark), instead of duplicating the
code, we create in this commit a common logic called pci-bridge-emul.
The idea of this logic is to emulate a root port PCI bridge
configuration space by providing configuration space read/write
operations, and faking behind the scenes the configuration space of a
PCI bridge. A PCI host controller driver simply has to call
pci_bridge_emul_conf_read() and pci_bridge_emul_conf_write() to
read/write the configuration space of the bridge.
By default, the PCI bridge configuration space is simply emulated by a
chunk of memory, but the PCI host controller can override the behavior
of the read and write operations on a per-register basis to do
additional actions if needed. We take care of complying with the
behavior of the PCI configuration space registers in terms of bits
that are read-write, read-only, reserved and write-1-to-clear.

The VMD removal path calls pci_stop_root_busi(), which tears down the pcie
tree, including detaching all of the attached drivers. During driver
detachment, devices may use pci_release_region() to release resources.
This path relies on the resource being accessible in resource tree.
By detaching the child domain from the parent resource domain prior to
stopping the bus, we are preventing the list traversal from finding the
resource to be freed. If we instead detach the resource after stopping
the bus, we will have properly freed the resource and detaching is
simply accounting at that point.
Without this order, the resource is never freed and is orphaned on VMD
removal, leading to a warning:
