Dynamic interrupt moderation RQ and SQ feature represented by
MLX5E_RQ_STATE_AM and MLX5E_SQ_STATE_AM enums respectively, is not
consistent with the feature naming in the driver, and with the formal
feature and library names.
Hence, change MLX5E_RQ_STATE_AM and MLX5E_SQ_STATE_AM enum type names in
core/en.h to MLX5E_RQ_STATE_DIM and MLX5E_SQ_STATE_DIM respectively.

If driver teardown is called while PCI is turned off, there is a race
between health recovery and teardown. If health recovery already started
it will wait 60 sec trying to see if PCI gets back and it can recover,
but actually there is no need to wait anymore once teardown was called.
Use the MLX5_BREAK_FW_WAIT flag which is set on driver teardown to break
waiting for PCI up.

When shutdown or remove callbacks are called the driver sets the flag
MLX5_BREAK_FW_WAIT, to stop waiting for FW as teardown was called. There
is no need to clear the bit as once shutdown or remove were called as
there is no way back, the driver is going down. Furthermore, if not
cleared the flag can be used also in other loops where we may wait while
teardown was already called.
Use test_bit() instead of test_and_clear_bit() as there is no need to
clear the flag.

ice: refactor mailbox overflow detection
Jake Keller says:
The primary motivation of this series is to cleanup and refactor the mailbox
overflow detection logic such that it will work with Scalable IOV. In
addition a few other minor cleanups are done while I was working on the
code in the area.
First, the mailbox overflow functions in ice_vf_mbx.c are refactored to
store the data per-VF as an embedded structure in struct ice_vf, rather than
stored separately as a fixed-size array which only works with Single Root
IOV. This reduces the overall memory footprint when only a handful of VFs
are used.
The overflow detection functions are also cleaned up to reduce the need for
multiple separate calls to determine when to report a VF as potentially
malicious.
Finally, the ice_is_malicious_vf function is cleaned up and moved into
ice_virtchnl.c since it is not Single Root IOV specific, and thus does not
belong in ice_sriov.c
I could probably have done this in fewer patches, but I split pieces out to
hopefully aid in reviewing the overall sequence of changes. This does cause
some additional thrash as it results in intermediate versions of the
refactor, but I think its worth it for making each step easier to
understand.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:

Viktor Malik says:
====================
I noticed that the verifier behaves incorrectly when attaching to fentry
of multiple functions of the same name located in different modules (or
in vmlinux). The reason for this is that if the target program is not
specified, the verifier will search kallsyms for the trampoline address
to attach to. The entire kallsyms is always searched, not respecting the
module in which the function to attach to is located.
As Yonghong correctly pointed out, there is yet another issue - the
trampoline acquires the module reference in register_fentry which means
that if the module is unloaded between the place where the address is
found in the verifier and register_fentry, it is possible that another
module is loaded to the same address in the meantime, which may lead to
errors.
This patch fixes the above issues by extracting the module name from the
BTF of the attachment target (which must be specified) and by doing the
search in kallsyms of the correct module. At the same time, the module
reference is acquired right after the address is found and only released
right before the program itself is unloaded.
---
Changes in v10:
- added the new test to DENYLIST.aarch64 (suggested by Andrii)
- renamed the test source file to match the test name
Changes in v9:
- two small changes suggested by Jiri Olsa and Jiri's ack
Changes in v8:
- added module_put to error paths in bpf_check_attach_target after the
module reference is acquired
Changes in v7:
- refactored the module reference manipulation (comments by Jiri Olsa)
- cleaned up the test (comments by Andrii Nakryiko)
Changes in v6:
- storing the module reference inside bpf_prog_aux instead of
bpf_trampoline and releasing it when the program is unloaded
(suggested by Jiri Olsa)
Changes in v5:
- fixed acquiring and releasing of module references by trampolines to
prevent modules being unloaded between address lookup and trampoline
allocation
Changes in v4:
- reworked module kallsyms lookup approach using existing functions,
verifier now calls btf_try_get_module to retrieve the module and
find_kallsyms_symbol_value to get the symbol address (suggested by
Alexei)
- included Jiri Olsa's comments
- improved description of the new test and added it as a comment into
the test source
Changes in v3:
- added trivial implementation for kallsyms_lookup_name_in_module() for
!CONFIG_MODULES (noticed by test robot, fix suggested by Hao Luo)
Changes in v2:
- introduced and used more space-efficient kallsyms lookup function,

Adds a new test that tries to attach a program to fentry of two
functions of the same name, one located in vmlinux and the other in
bpf_testmod.
To avoid conflicts with existing tests, a new function
"bpf_fentry_shadow_test" was created both in vmlinux and in bpf_testmod.
The previous commit fixed a bug which caused this test to fail. The
verifier would always use the vmlinux function's address as the target
trampoline address, hence trying to create two trampolines for a single
address, which is forbidden.
The test (similarly to other fentry/fexit tests) is not working on arm64
at the moment.

This resolves two problems with attachment of fentry/fexit/fmod_ret/lsm
to functions located in modules:
1. The verifier tries to find the address to attach to in kallsyms. This
is always done by searching the entire kallsyms, not respecting the
module in which the function is located. Such approach causes an
incorrect attachment address to be computed if the function to attach
to is shadowed by a function of the same name located earlier in
kallsyms.
2. If the address to attach to is located in a module, the module
reference is only acquired in register_fentry. If the module is
unloaded between the place where the address is found
(bpf_check_attach_target in the verifier) and register_fentry, it is
possible that another module is loaded to the same address which may
lead to potential errors.
Since the attachment must contain the BTF of the program to attach to,
we extract the module from it and search for the function address in the
correct module (resolving problem no. 1). Then, the module reference is
taken directly in bpf_check_attach_target and stored in the bpf program
(in bpf_prog_aux). The reference is only released when the program is
unloaded (resolving problem no. 2).

The mrbland board was never actually produced and there has been no
activity around the board for quite some time. It seems highly
unlikely to magically get revived. There should be nobody in need of
these device trees, so let's delete them. If somehow the project
resurrects itself then we can re-add support, perhaps just for -rev1+.

lazor-rev0 was a pile of parts. While I kept the pile of parts for
lazor running on my desk for longer than I usually do, those days are
still long past. Let's finally delete support for lazor-rev0.

The earliest kingoftown that I could find in my pile of boards was
-rev2 and even that revision looks pretty rough (plastics on the case
are very unfinished). Though I don't actually have details about how
many -rev0 devices were produced, I can't imagine anyone still using
one. Let's delete support.

The earliest wormdingler I could find in my pile of hardware is
-rev1. I believe that -rev0 boards were just distributed as a pile of
components with no case. At this point I can't imagine anyone needing
to make wormdingler-rev0 work, so let's delete support for it.

In order for consumers of RPMCC XO clock to probe successfully
their parent needs to be feed with reference clock to obtain proper rate,
add fixed xo-board clock and supply it to rpmcc to make consumers happy.
Frequency setting is left per board basis just like on other recent trees.

For 64KiB of the I/O region, the I/O ports of the legacy PCI devices are
located in the range of 0x0 to 0x10000. Hence, fix the bogus PCI addresses
(0x0fe00000, 0x31e00000, 0x35e00000) specified in the ranges property for
I/O region.
While at it, let's use the missing 0x prefix for the addresses.
