344fa0bad6 drivers: thermal: tsens: Work with old DTBs
In order for the old DTBs to continue working, the new interrupt code
must not return an error if interrupts are not defined. Don't return an
error in case of -ENXIO.

50cc02e599 x86/context-tracking: Remove exception_enter/exit() from KVM_PV_REASON_PAGE_NOT_PRESENT async page fault
This is a leftover. Page faults, just like most other exceptions,
are protected inside user_exit() / user_enter() calls in x86 entry code
when we fault from userspace. So this pair of calls is now superfluous.

ee6352b2c4 x86/context-tracking: Remove exception_enter/exit() from do_page_fault()
do_page_fault(), like other exceptions, is already covered by
user_enter() and user_exit() when the exception triggers in userspace.

As explained in:

  8c84014f3b ("x86/entry: Remove exception_enter() from most trap handlers")

exception_enter/exit() only remained to handle possible page fault from
kernel mode while context tracking is in CONTEXT_USER mode, ie: on
kernel entry before we manage to call user_exit(). The only known
offender was do_fast_syscall_32() fetching EBP register from where
vDSO stashed it.

Meanwhile this got fixed in:

  9999c8c01f ("x86/entry: Call enter_from_user_mode() with IRQs off")

that moved enter_from_user_mode() before the call to get_user().

So we can safely remove it now.

194efb6e26 clk: gate: Add support for specifying parents via DT/pointers
After commit fc0c209c14 ("clk: Allow parents to be specified without
string names") we can use DT or direct clk_hw pointers to specify
parents. Create a generic function that shouldn't be used very often to
encode the multitude of ways of registering a gate clk with different
parent information. Then add a bunch of wrapper macros that only pass
down what needs to be passed down to the generic function to support
this with less arguments.

9611b3aacc clk: mux: Add support for specifying parents via DT/pointers
After commit fc0c209c14 ("clk: Allow parents to be specified without
string names") we can use DT or direct clk_hw pointers to specify

encode the multitude of ways of registering a mux clk with different
parent information. Then add a bunch of wrapper macros that only pass
down what needs to be passed down to the generic function to support
this with less arguments.

Note: the msm drm driver passes an anonymous array through the macro
which seems to confuse my compiler. Adding a parenthesis around the
whole thing at the call site seems to fix it but it must be wrong. Maybe
it's better to split this patch and pick out the array bits there?

a754bd5f18 block: Allow t10-pi to be modular
Currently t10-pi can only be built into the block layer which via
crc-t10dif pulls in a whole chunk of the Crypto API.  In fact all
users of t10-pi work as modules and there is no reason for it to
always be built-in.

This patch adds a new hidden option for t10-pi that is selected
automatically based on BLK_DEV_INTEGRITY and whether the users
of t10-pi are built-in or not.

Jeff Kirsher says:

====================
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.

Andrew Lunn says:

====================
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
which switches. Make the interrupt names unique by including the
device name in the interrupt name. For the SERDES interrupt, also
include the port number. As a result of these patches ZII devel C
looks like:

 50:          0  gpio-vf610  27 Level     mv88e6xxx-0.1:00
 54:          0  mv88e6xxx-g1   3 Edge      mv88e6xxx-0.1:00-g1-atu-prob

101:          0  mv88e6xxx-g2  15 Edge      mv88e6xxx-0.2:00-watchdog

Interrupt names like !mdio-mux!mdio@2!switch@0!mdio:01 are created by
phylib for the integrated PHYs. The mv88e6xxx driver does not
determine these names.

6412bb396a net/mlx5e: Fix hairpin RSS table size
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.

1f0593e791 Revert "net/mlx5: Support lockless FTE read lookups"
This reverts commit 7dee607ed0.

During cleanup path, FTE's parent node group is removed which is
referenced by the FTE while freeing the FTE.
Hence FTE's lockless read lookup optimization done in cited commit is
not possible at the moment.

Hence, revert the commit.

This avoid below KAZAN call trace.

After cited patch, 3rd party monitoring tools that tracks these error

c5706c7def gpio: max77620: Add missing dependency on GPIOLIB_IRQCHIP
Driver fails to compile in a minimized kernel's configuration because of
the missing dependency on GPIOLIB_IRQCHIP.

 error: ‘struct gpio_chip’ has no member named ‘irq’
   44 |   virq = irq_find_mapping(gpio->gpio_chip.irq.domain, offset);

Pull tpmd fixes from Jarkko Sakkinen:
 "There has been a bunch of reports (e.g. [*]) reporting that when
  commit 5b359c7c43 ("tpm_tis_core: Turn on the TPM before probing
  IRQ's") and subsequent fixes are applied it causes boot freezes on
  some machines.

  Unfortunately hardware where this causes a failure is not widely
  available (only one I'm aware is Lenovo T490), which means we cannot
  predict yet how long it will take to properly fix tpm_tis interrupt
  probing.

  Thus, the least worst short term action is to revert the code to the
  state before this commit. In long term we need fix the tpm_tis probing
  code to work on machines that Stefan's patches were supposed to fix.

  With these patches reverted nothing fatal happens, TPM is fallbacked
  to be used in polling mode (which is not in the end too bad because
  there are no high throughput workloads for TPM).

2c344ae245 igc: Add support for TX timestamping
This adds support for timestamping packets being transmitted.

Based on the code from i210. The basic differences is that i225 has 4
registers to store the transmit timestamps (i210 has one). Right now,
we only support retrieving from one register, support for using the
other registers will be added later.
