This series changes the way GSI register offset are specified, using
the "reg" mechanism currently used for IPA registers. A follow-on
series will extend this work so fields within GSI registers are also
specified this way.
The first patch rearranges the GSI register initialization code so
it is similar to the way it's done for the IPA registers. The
second identifies all the GSI registers in an enumerated type.
The third introduces "gsi_reg-v3.1.c" and uses the "reg" code to
define one GSI register offset. The second-to-last patch just
adds "gsi_reg-v3.5.1.c", because that version introduces a new
register not previously defined. All the rest just define the
rest of the GSI register offsets using the "reg" mechanism.

====================
devlink: params cleanups and devl_param_driverinit_value_get() fix
The primary motivation of this patchset is the patch #6, which fixes an
issue introduced by
075935f0ae0f ("devlink: protect devlink param list
by instance lock") and reported by Kim Phillips <kim.phillips@amd.com>
(https://lore.kernel.org/netdev/
719de4f0-76ac-e8b9-38a9-
167ae239efc7@amd.com/)
and my colleagues doing mlx5 driver regression testing.
The basis idea is that devl_param_driverinit_value_get() could be
possible to the called without holding devlink intance lock in
most of the cases (all existing ones in the current codebase),
which would fix some mlx5 flows where the lock is not held.
To achieve that, make sure that the param value does not change between
reloads with patch #2.
Also, convert the param list to xarray which removes the worry about
list_head consistency when doing lockless lookup.
The rest of the patches are doing some small related cleanup of things
that poke me in the eye during the work.

devlink: allow to call devl_param_driverinit_value_get() without holding instance lock
If the driver maintains following basic sane behavior, the
devl_param_driverinit_value_get() function could be called without
holding instance lock:
1) Driver ensures a call to devl_param_driverinit_value_get() cannot
race with registering/unregistering the parameter with
the same parameter ID.
2) Driver ensures a call to devl_param_driverinit_value_get() cannot
race with devl_param_driverinit_value_set() call with
the same parameter ID.
3) Driver ensures a call to devl_param_driverinit_value_get() cannot
race with reload operation.
By the nature of params usage, these requirements should be
trivially achievable. If the driver for some off reason
is not able to comply, it has to take the devlink->lock while
calling devl_param_driverinit_value_get().
Remove the lock assertion and add comment describing
the locking requirements.
This fixes a splat in mlx5 driver introduced by the commit
referenced in the "Fixes" tag.

Add test cases for large scale MDB dump to make sure that all the

Specifically, create 2 bridges with 32 ports and add 256 MDB entries in

net: skbuff: drop the word head from skb cache
skbuff_head_cache is misnamed (perhaps for historical reasons?)
because it does not hold heads. Head is the buffer which skb->data
points to, and also where shinfo lives. struct sk_buff is a metadata
structure, not the head.
Eric recently added skb_small_head_cache (which allocates actual
head buffers), let that serve as an excuse to finally clean this up :)

net: ipa: prepare for GSI register updtaes
An upcoming series (or two) will convert the definitions of GSI
registers used by IPA so they use the "IPA reg" mechanism to specify
register offsets and their fields. This will simplify implementing
the fairly large number of changes required in GSI registers to
support more than 32 GSI channels (introduced in IPA v5.0).
A few minor problems and inconsistencies were found, and they're
fixed here. The last three patches in this series change the
"ipa_reg" code to separate the IPA-specific part (the base virtual
address, basically) from the generic register part, and the now-
generic code is renamed to use just "reg_" or "REG_" as a prefix
rather than "ipa_reg" or "IPA_REG_".

net: ipa: start generalizing "ipa_reg"
IPA register definitions have evolved with each new version. The
changes required to support more than 32 endpoints in IPA v5.0 made
it best to define a unified mechanism for defining registers and
their fields.
GSI register definitions, meanwhile, have remained fairly stable.
And even as the total number of IPA endpoints goes beyond 32, the
number of GSI channels on a given EE that underly endpoints still
remains 32 or less.
Despite that, GSI v3.0 (which is used with IPA v5.0) extends the
number of channels (and events) it supports to be about 256, and as
a result, many GSI register definitions must change significantly.
To address this, we'll use the same "ipa_reg" mechanism to define
the GSI registers.
As a first step in generalizing the "ipa_reg" to also support GSI
registers, isolate the definitions of the "ipa_reg" and "ipa_regs"
structure types (and some supporting macros) into a new header file,
and remove the "ipa_" and "IPA_" from symbol names.
Separate the IPA register ID validity checking from the generic
check that a register ID is in range. Aside from that, this is
intended to have no functional effect on the code.

net: introduce rps_default_mask
Real-time setups try hard to ensure proper isolation between time
critical applications and e.g. network processing performed by the

activity away from the isolated core.
If the network configuration is dynamic, with netns and devices
routinely created at run-time, enforcing the correct RPS setting
on each newly created device allowing to transient bad configuration
became complex.
Additionally, when multi-queue devices are involved, configuring rps
in user-space on each queue easily becomes very expensive, e.g.
some setups use veths with per cpu queues.
These series try to address the above, introducing a new
sysctl knob: rps_default_mask. The new sysctl entry allows
configuring a netns-wide RPS mask, to be enforced since receive
queue creation time without any fourther per device configuration
required.
Additionally, a simple self-test is introduced to check the
