The generic GPIO library directly implement code for of_find_gpio()
which is only used with CONFIG_OF and causes compilation problems
on archs that do not even have stubs for OF functions, especially
on UM that does not implement any IO remap functions.
Move the function to gpiolib-of.c, implement a static inline stub
in gpiolib.h returning PTR_ERR(-ENOENT) if CONFIG_OF_GPIO is not
set and be done with it.

This one is pretty obvious: on UM Linux compilation of things
like allmodconfig and allyesconfig will fail due to the
absence of IO memory. Simply make these drivers depend on
HAS_IOMEM, it has been implicitly assumed all the time, so
just make it explicit.
The generic MMIO library also assumes that IOMEM is present
so make also this depend on HAS_IOMEM.

These files were only including module.h for exception table
related functions. We've now separated that content out into its
own file "extable.h" so now move over to that and avoid all the
extra header content in module.h that we don't really need to compile
these files.
One uses "print_modules" so that prevents us removing module.h in
that case, however.

====================
rxrpc: More fixes and adjustments
This set of patches contains some more fixes and adjustments:
(1) Actually display the retransmission indication previously added to the
tx_data trace.
(2) Switch to Congestion Avoidance mode properly at cwnd==ssthresh rather
than relying on detection during an overshoot and correction.
(3) Reduce ssthresh to the peer's declared receive window.
(4) The offset field in rxrpc_skb_priv can be dispensed with and the error
field is no longer used. Get rid of them.
(5) Keep the call timeouts as ktimes rather than jiffies to make it easier
to deal with RTT-based timeout values in future. Rounding to jiffies
is still necessary when the system timer is set.
(6) Fix the call timer handling to avoid retriggering of expired timeout
actions.

After the 48d2ab609b6b ("net: mpls: Fixups for GSO"), MPLS handling in
openvswitch was changed to have network header pointing to the start of the
MPLS headers and inner_network_header pointing after the MPLS headers.
However, key_extract was missed by the mentioned commit, causing incorrect
headers to be set when a MPLS packet just enters the bridge or after it is
recirculated.

If fi->fib_nhs is zero, the router interface pointer is uninitialized, as shown by
this warning:
drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c: In function 'mlxsw_sp_router_fib_event':
drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c:1674:21: error: 'r' may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c:1643:23: note: 'r' was declared here
This changes the loop so we handle the case the same way as finding no router
interface pointer attached to one of the nexthops to ensure we always
trap here instead of using uninitialized data.

Build-testing this driver with -Wmaybe-uninitialized gives a new false-positive
warning that I can't really explain:
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c: In function 'mlx5e_configure_flower':
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:509:3: error: 'old_attr' may be used uninitialized in this function [-Werror=maybe-uninitialized]
It's obvious from the code that 'old_attr' is initialized whenever 'old'
is non-NULL here. The warning appears with all versions I tested from gcc-4.7
through gcc-6.1, and I could not come up with a way to rewrite the function
in a more readable way that avoids the warning, so I'm adding another
initialization to shut it up.

A recent cleanup marked cxgb4_dcb_enabled as 'static', which is correct, but this ignored
how the symbol is also exported. In addition, the export can be compiled out when modules
are disabled, causing a harmless compiler warning in configurations for which it is not
used at all:
drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:282:12: error: 'cxgb4_dcb_enabled' defined but not used [-Werror=unused-function]
This removes the export and moves the function into the correct #ifdef so we only build
it when there are users.

With the newly added support for IFLA_VF_VLAN_LIST netlink messages,
we get a warning about potential uninitialized variable use in
the parsing of the user input when enabling the -Wmaybe-uninitialized
warning:
net/core/rtnetlink.c: In function 'do_setvfinfo':
net/core/rtnetlink.c:1756:9: error: 'ivvl$' may be used uninitialized in this function [-Werror=maybe-uninitialized]
I have not been able to prove whether it is possible to arrive in
this code with an empty IFLA_VF_VLAN_LIST block, but if we do,
then ndo_set_vf_vlan gets called with uninitialized arguments.
This adds an explicit check for an empty list, making it obvious
to the reader and the compiler that this cannot happen.

The commit 879c7220e828 ("net: pktgen: Observe needed_headroom
of the device") increased the 'pkt_overhead' field value by
LL_RESERVED_SPACE.
As a side effect the generated packet size, computed as:
/* Eth + IPh + UDPh + mpls */
datalen = pkt_dev->cur_pkt_size - 14 - 20 - 8 -
pkt_dev->pkt_overhead;
is decreased by the same value.
The above changed slightly the behavior of existing pktgen users,
and made the procfs interface somewhat inconsistent.
Fix it by restoring the previous pkt_overhead value and using
LL_RESERVED_SPACE as extralen in skb allocation.
Also, change pktgen_alloc_skb() to only partially reserve
the headroom to allow the caller to prefetch from ll header
start.

If the mac address origin is not dt, you can only safely assign a mac
address after "link up" of the device. If the link is off the clocks are
disabled and because of issues assigning registers when clocks are off the
new mac address cannot be written in .ndo_set_mac_address() on some soc's.
This fix sets the mac address unconditionally in fec_restart(...) and
ensures consistency between fec registers and the network layer.

The change adds a new device node with description of generic SRAM
on-chip memory found on NXP LPC32xx SoC series and connected to AHB
matrix slave port 3.
Note that NXP LPC3220 SoC has 128KiB of SRAM memory, the other
LPC3230, LPC3240 and LPC3250 SoCs all have 256KiB SRAM space,
in the shared DTSI file this change specifies 128KiB SRAM size.
Also it's worth to mention that the SRAM area contains of 64KiB banks,
2 banks on LPC3220 and 4 banks on the other SoCs from the series, and
all SRAM banks but the first one have independent power controls,
the description of this feature will be added with the introduction of
power domains for the SoC series.

This is an effective no-op in terms of user observable behaviour.
By preventing the overwrite of non-null extra1/extra2 fields
in addrconf_sysctl() we can enable the use of proc_dointvec_minmax().
This allows us to eliminate the constant min/max (1..255) trampoline
function that is addrconf_sysctl_hop_limit().
This is nice because it simplifies the code, and allows future
sysctls with constant min/max limits to also not require trampolines.
We still can't eliminate the trampoline for mtu because it isn't
actually a constant (it depends on other tunables of the device)
and thus requires at-write-time logic to enforce range.
