Separate the low-level MMIO static inline functions and macros, such
as {read,write}{b,w,l,q}(), into their own header file under
arch/riscv/include: asm/mmio.h.  This is done to break a header
dependency chain that arises when both asm/pgtable.h and asm/io.h are
included by asm/timex.h.  Since the problem is related to the legacy
I/O port support in asm/io.h, this allows files under arch/riscv that
encounter those issues to simply include asm/mmio.h instead, and
bypass the legacy I/O port functions.  Existing users of asm/io.h
don't need to change anything, since asm/mmio.h is included by
asm/io.h.

  A recent change to disable interrupts before calling

When netdevice with offloaded BPF programs is destroyed
the programs are orphaned and removed from the program
IDA - their IDs get released (the programs may remain
accessible via existing open file descriptors and pinned
files). After IDs are released they are set to 0.

This confuses dev_change_xdp_fd() because it compares
the __dev_xdp_query() result where 0 means no program
with prog->aux->id where 0 means orphaned.

dev_change_xdp_fd() would have incorrectly returned success
even though it had not installed the program.

Since drivers already catch this case via bpf_offload_dev_match()
let them handle this case. The error message drivers produce in
this case ("program loaded for a different device") is in fact
correct as the orphaned program must had to be loaded for a
different device.

Historically linux tried to stick to RFC 791, 1122, 2003
for IPv4 ID field generation.

RFC 6864 made clear that no matter how hard we try,
we can not ensure unicity of IP ID within maximum
lifetime for all datagrams with a given source
address/destination address/protocol tuple.

Linux uses a per socket inet generator (inet_id), initialized
at connection startup with a XOR of 'jiffies' and other
fields that appear clear on the wire.

Thiemo Nagel pointed that this strategy is a privacy
concern as this provides 16 bits of entropy to fingerprint
devices.

Let's switch to a random starting point, this is just as
good as far as RFC 6864 is concerned and does not leak
anything critical.

Intel Wired LAN Driver Updates 2019-11-01

This series contains updates to e1000, igb, igc, ixgbe, i40e and driver
documentation.

Lyude Paul fixes an issue where a fatal read error occurs when the
device is unplugged from the machine.  So change the read error into a
warn while the device is still present.

Manfred Rudigier found that the i350 device was not apart of the "Media
Auto Sense" feature, yet the device supports it.  So add the missing
i350 device to the check and fix an issue where the media auto sense
would flip/flop when no cable was connected to the port causing spurious
kernel log messages.

I fixed an issue where the fix to resolve receive buffer starvation was
applied in more than one place in the driver, one being the incorrect
location in the i40e driver.

Wenwen Wang fixes a potential memory leak in e1000 where allocated
memory is not properly cleaned up in one of the error paths.

Jonathan Neuschäfer cleans up the driver documentation to be consistent
and remove the footnote reference, since the footnote no longer exists in
the documentation.

Igor Pylypiv cleans up a duplicate clearing of a bit, no need to clear
it twice.

At least on the i350 there is an annoying behavior that is maybe also
present on 82580 devices, but was probably not noticed yet as MAS is not
widely used.

If no cable is connected on both fiber/copper ports the media auto sense
code will constantly swap between them as part of the watchdog task and
produce many unnecessary kernel log messages.

The swap code responsible for this behavior (switching to fiber) should
not be executed if the current media type is copper and there is no signal
detected on the fiber port. In this case we can safely wait until the
AUTOSENSE_EN bit is cleared.
