In the process of converting the bit manipulation macros were converted
to use GENMASK(), the compiler reported a value too big for the field.
The offending statement was trying to write 0x100 into a 5-bit field.
An accompaning comment says to set bit 3, thus the code is changed
appropriately.

This error has been in the driver since its initial submission.

====================
mvpp2: per-cpu buffers

This patchset workarounds an PP2 HW limitation which prevents to use
per-cpu rx buffers.
The first patch is just a refactor to prepare for the second one.
The second one allocates percpu buffers if the following conditions are met:
- CPU number is less or equal 4
- no port is using jumbo frames

If the following conditions are not met at load time, of jumbo frame is enabled
later on, the shared allocation is reverted.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Every mvpp2 unit can use up to 8 buffers mapped by the BM (the HW buffer
manager). The HW will place the frames in the buffer pool depending on the
frame size: short (< 128 bytes), long (< 1664) or jumbo (up to 9856).

As any unit can have up to 4 ports, the driver allocates only 2 pools,
one for small and one long frames, and share them between ports.
When the first port MTU is set higher than 1664 bytes, a third pool is
allocated for jumbo frames.

This shared allocation makes impossible to use percpu allocators,
and creates contention between HW queues.

If possible, i.e. if the number of possible CPU are less than 8 and jumbo
frames are not used, switch to a new scheme: allocate 8 per-cpu pools for
short and long frames and bind every pool to an RXQ.

When the first port MTU is set higher than 1664 bytes, the allocation
scheme is reverted to the old behaviour (3 shared pools), and when all
ports MTU are lowered, the per-cpu buffers are allocated again.

devlink_free is complaining right here:

	WARN_ON(!list_empty(&devlink->port_list));

This happens because devlink_port_unregister is no longer done right
away in dsa_port_setup when a DSA_PORT_TYPE_USER has failed.
Vivien said about this change that:

    Also no need to call devlink_port_unregister from within dsa_port_setup
    as this step is inconditionally handled by dsa_port_teardown on error.

which is not really true. The devlink_port_unregister function _is_
being called unconditionally from within dsa_port_setup, but not for
this port that just failed, just for the previous ones which were set
up.

ports_teardown:
	for (i = 0; i < port; i++)
		dsa_port_teardown(&ds->ports[i]);

Initially I was tempted to fix this by extending the "for" loop to also
cover the port that failed during setup. But this could have potentially
unforeseen consequences unrelated to devlink_port or even other types of
ports than user ports, which I can't really test for. For example, if
for some reason devlink_port_register itself would fail, then
unconditionally unregistering it in dsa_port_teardown would not be a
smart idea. The list might go on.

So just make dsa_port_setup undo the setup it had done upon failure, and
let the for loop undo the work of setting up the previous ports, which
are guaranteed to be brought up to a consistent state.

net: dsa: mv88e6xxx: centralize SERDES IRQ handling

Following Marek's work on the abstraction of the SERDES lanes mapping, this
series trades the .serdes_irq_setup and .serdes_irq_free callbacks for new
.serdes_irq_mapping, .serdes_irq_enable and .serdes_irq_status operations.

This has the benefit to limit the various SERDES implementations to simple
register accesses only; centralize the IRQ handling and mutex locking logic;
as well as reducing boilerplate in the driver.
====================

The .serdes_irq_setup are all following the same steps: get the SERDES
lane, get the IRQ mapping, request the IRQ, then enable it. So do
the .serdes_irq_free implementations: get the SERDES lane, disable
the IRQ, then free it.

This patch removes these operations in favor of generic functions.

Because the mapping between a SERDES interface and its lane is static,

simply return 0 if there is no lane, just like the IRQ mapping.

This way we can keep a simple and intuitive API using unsigned lane
numbers while simplifying the implementations with single return

Pull x86 fixes from Thomas Gleixner:
 "A set of fixes for x86:

   - Fix the bogus detection of 32bit user mode for uretprobes which
     caused corruption of the user return address resulting in
     application crashes. In the uprobes handler in_ia32_syscall() is
     obviously always returning false on a 64bit kernel. Use
     user_64bit_mode() instead which works correctly.

   - Prevent large page splitting when ftrace flips RW/RO on the kernel
     text which caused iTLB performance issues. Ftrace wants to be
     converted to text_poke() which avoids the problem, but for now
     allow large page preservation in the static protections check when
     the change request spawns a full large page.

   - Prevent arch_dynirq_lower_bound() from returning 0 when the IOAPIC
     is configured via device tree. In the device tree case the GSI 1:1
     mapping is meaningless therefore the lower bound which protects the
     GSI range on ACPI machines is irrelevant. Return the lower bound
     which the core hands to the function instead of blindly returning 0
     which causes the core to allocate the invalid virtual interupt
     number 0 which in turn prevents all drivers from allocating and
     requesting an interrupt.

   - Remove the bogus initialization of LDR and DFR in the 32bit bigsmp
     APIC driver. That uses physical destination mode where LDR/DFR are
     ignored, but the initialization and the missing clear of LDR caused
     the APIC to be left in a inconsistent state on kexec/reboot.

   - Clear LDR when clearing the APIC registers so the APIC is in a well
     defined state.

This patch adds handlers for PLDM over NC-SI command response.

This enables NC-SI driver recognizes the packet type so the responses
don't get dropped as unknown packet type.

PLDM over NC-SI are not handled in kernel driver for now, but can be
passed back to user space via Netlink for further handling.

Call to 'pci_free_irq_vectors()' are missing both in the error handling
path of the probe function, and in the remove function.
Add them.

This change enables the use of SW timestamping on the Raspberry Pi 4.

bcmgenet's transmit function bcmgenet_xmit() implements software
timestamping. However the SOF_TIMESTAMPING_TX_SOFTWARE capability was
missing and only SOF_TIMESTAMPING_RX_SOFTWARE was announced. By using
ethtool_ops bcmgenet_ethtool_ops() as get_ts_info(), the
SOF_TIMESTAMPING_TX_SOFTWARE capability is announced.

the following tdc test fails on Fedora:

 # ./tdc.py -e 2638
  -- ns/SubPlugin.__init__
 Test 2638: Add matchall and try to get it
 -----> prepare stage *** Could not execute: "$TC qdisc add dev $DEV1 clsact"
 -----> prepare stage *** Error message: "/bin/sh: ip: command not found"

 -----> prepare stage *** Aborting test run.

Let nsPlugin.py use the 'IP' variable introduced with commit 92c1a19e
("tc-tests: added path to ip command in tdc"), so that the path to 'ip' is
correctly resolved to the value we have in tdc_config.py.

Devlink port index attribute is returned to users as u32 through
netlink response.
Change index data type from 'unsigned' to 'unsigned int' to avoid
below checkpatch.pl warning.

net: tls: add socket diag

The current kernel does not provide any diagnostic tool, except
getsockopt(TCP_ULP), to know more about TCP sockets that have an upper
layer protocol (ULP) on top of them. This series extends the set of
information exported by INET_DIAG_INFO, to include data that are
specific to the ULP (and that might be meaningful for debug/testing
purposes).

patch 1/3 ensures that the control plane reads/updates ULP specific data
using RCU.

patch 2/3 extends INET_DIAG_INFO and allows knowing the ULP name for
each TCP socket that has done setsockopt(TCP_ULP) successfully.

patch 3/3 extends kTLS to let programs like 'ss' know the protocol
version and the cipher in use.

Changes since v2:
- remove unneeded #ifdef and fix reverse christmas tree in
  tls_get_info(), thanks to Jakub Kicinski

Changes since v1:
- don't worry about grace period when accessing ulp_ops, thanks to
  Jakub Kicinski and Eric Dumazet
- use rcu_dereference() to access ULP data in tls get_info(), and
  test against NULL value, thanks to Jakub Kicinski
- move RCU protected section inside tls get_info(), thanks to Jakub
  Kicinski

Changes since RFC:
- some coding style fixes, thanks to Jakub Kicinski
- add X_UNSPEC as lowest value of uAPI enums, thanks to Jakub Kicinski
- fix assignment of struct nlattr *start, thanks to Jakub Kicinski
- let tls dump RXCONF and TXCONF, suggested by Jakub Kicinski
- don't dump anything if TLS version or cipher are 0 (but still return a
  constant size in get_aux_size()), thanks to Boris Pismenny
- constify first argument of get_info() and get_size()
- use RCU to access access ulp_ops, like it's done for ca_ops
- add patch 1/3, from Jakub Kicinski
