The priv->response_length can hold the size of an response or an negative
error code, and the tpm_common_read() needs to handle both cases correctly.
Changed the type of response_length to signed and accounted for negative
value in tpm_common_read().

Simplify and fix the version information displayed by the driver.
The new info better relects what is needed to support the hardware.
Prev:
Version: 4.8.0, Pipeline 22169 0x4001, Rev 0, Bond 5, CSR 311, IRQ 2
New:
Version: 4.8.0, Id: 0x4001 Hw Rev: 5 OTP Config Select: 15
- Remove pipeline, CSR and IRQ because version x.y.z already incorporates
this information.
- Remove bond number because it is not used.
- Remove rev number because register was not implemented, always 0
- Add HW Rev ID register to replace rev number
- Add OTP config select to show the user configuration chosen by
the configurable GPIO pins on start-up

There are few cases where the ndo_uninit() handler might be not
called if an error happens while device is initialized.
Since vlan_newlink() calls vlan_changelink() before
trying to register the netdevice, we need to make sure
vlan_dev_uninit() has been called at least once,
or we might leak allocated memory.

Make sure the NIC drops packets that are larger than the
specified MTU.
The front end of the NIC will accept packets larger than MTU and
will copy all the data it can to fill up the driver's posted
buffers - if the buffers are not long enough the packet will
then get dropped. With the Rx SG buffers allocagted as full
pages, we are currently setting up more space than MTU size
available and end up receiving some packets that are larger
than MTU, up to the size of buffers posted. To be sure the
NIC doesn't waste our time with oversized packets we need to
lie a little in the SG descriptor about how long is the last
SG element.
At dealloc time, we know the allocation was a page, so the
deallocation doesn't care about what length we put in the
descriptor.

Currently the max number of channels is limited to 64, which is half of
the indirection table size to allow some flexibility. But on servers
with more than 64 cores, users may want to utilize more queues.
This patch increases the advertised max number of channels to 128 by
changing the ratio between channels and indirection table slots to 1:1.
At the same time, the driver still enable no more than 64 channels at
loading. Users can change it by ethtool afterwards.

As was stated in the bug report, the reason is that gcc runs into a corner
case in the register allocator that is rather hard to fix in a good way.
As there is an easy way to work around it, just add a comment and the
barrier that stops gcc from trying to overoptimize the function.

1GbE Intel Wired LAN Driver Updates 2020-01-06
This series contains updates to igc to add basic support for
timestamping.
Vinicius adds basic support for timestamping and enables ptp4l/phc2sys
to work with i225 devices. Initially, adds the ability to read and
adjust the PHC clock. Patches 2 & 3 enable and retrieve hardware
timestamps. Patch 4 implements the ethtool ioctl that ptp4l uses to
check what timestamping methods are supported. Lastly, added support to
do timestamping using the "Start of Packet" signal from the PHY, which
is now supported in i225 devices.
While i225 does support multiple PTP domains, with multiple timestamping
registers, we currently only support one PTP domain and use only one of
the timestamping registers for implementation purposes.

Unique mv88e6xxx IRQ names
There are a few boards which have multiple mv88e6xxx switches. With
such boards, it can be hard to determine which interrupts belong to

include the port number. As a result of these patches ZII devel C

Pull tracing fixes from Steven Rostedt:
"Various tracing fixes:
- kbuild found missing define of MCOUNT_INSN_SIZE for various build
configs
- Initialize variable to zero as gcc thinks it is used undefined (it
really isn't but the code is subtle enough that this doesn't hurt)
- Convert from do_div() to div64_ull() to prevent potential divide by
zero
- Unregister a trace point on error path in sched_wakeup tracer
- Use signed offset for archs that can have stext not be first
- A simple indentation fix (whitespace error)"
* tag 'trace-v5.5-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
tracing: Fix indentation issue
kernel/trace: Fix do not unregister tracepoints when register sched_migrate_task fail
tracing: Change offset type to s32 in preempt/irq tracepoints
ftrace: Avoid potential division by zero in function profiler
tracing: Have stack tracer compile when MCOUNT_INSN_SIZE is not defined
tracing: Define MCOUNT_INSN_SIZE when not defined without direct calls
tracing: Initialize val to zero in parse_entry of inject code

Whenever adding new member of rule object we attach it to 2 lists,
These 2 lists should be initialized first.

Set hairpin table size to the corret size, based on the groups that
would be created in it. Groups are laid out on the table such that a
group occupies a range of entries in the table. This implies that the
group ranges should have correspondence to the table they are laid upon.
The patch cited below made group 1's size to grow hence causing
overflow of group range laid on the table.

No need for an atomic refcounter for the STE and hashtables.
These are internal SW steering resources and they are always
under domain mutex.
This also fixes the following refcount error:
refcount_t: addition on 0; use-after-free.
