Currently, "# end of ..." is inserted when the menu goes back to its
parent.
Hence, an empty menu:
menu "Foo"
endmenu
... ends up with unbalanced menu comments, like this:
#
# Foo
#
Let's close the menu comments properly:
#
# Foo
#
# end of Foo

====================
bpf-next 2022-02-17
We've added 29 non-merge commits during the last 8 day(s) which contain
a total of 34 files changed, 1502 insertions(+), 524 deletions(-).
The main changes are:
1) Add BTFGen support to bpftool which allows to use CO-RE in kernels without
BTF info, from Mauricio Vásquez, Rafael David Tinoco, Lorenzo Fontana and
Leonardo Di Donato. (Details: https://lpc.events/event/11/contributions/948/)
2) Prepare light skeleton to be used in both kernel module and user space
and convert bpf_preload.ko to use light skeleton, from Alexei Starovoitov.
3) Rework bpftool's versioning scheme and align with libbpf's version number;
also add linked libbpf version info to "bpftool version", from Quentin Monnet.
4) Add minimal C++ specific additions to bpftool's skeleton codegen to
facilitate use of C skeletons in C++ applications, from Andrii Nakryiko.
5) Add BPF verifier sanity check whether relative offset on kfunc calls overflows
desc->imm and reject the BPF program if the case, from Hou Tao.
6) Fix libbpf to use a dynamically allocated buffer for netlink messages to
avoid receiving truncated messages on some archs, from Toke Høiland-Jørgensen.
7) Various follow-up fixes to the JIT bpf_prog_pack allocator, from Song Liu.
8) Various BPF selftest and vmtest.sh fixes, from Yucong Sun.
9) Fix bpftool pretty print handling on dumping map keys/values when no BTF
is available, from Jiri Olsa and Yinjun Zhang.
10) Extend XDP frags selftest to check for invalid length, from Lorenzo Bianconi.

The mmc0 clock gate bit was mistakenly assigned to "i2s" clock.
You can find that the same bit is assigned to "mmc0" too.
It leads to mmc0 hang for a long time after any sound activity
also it prevented PM_SLEEP to work properly.
I guess it was introduced by copy-paste from jz4740 driver
where it is really controls I2S clock gate.

Just like in commit 05cf3ec00d46 ("clk: qcom: gcc-msm8996: Drop (again)
gcc_aggre1_pnoc_ahb_clk") adding NoC clocks turned out to be a huge
mistake, as they cause a lot of issues at little benefit (basically
letting Linux know about their children's frequencies), especially when
mishandled or misconfigured.
Adding these ones broke SDCC approx 99 out of 100 times, but that somehow
went unnoticed. To prevent further issues like this one, remove them.
This commit is effectively a revert of 74a33fac3aab ("clk: qcom:
gcc-msm8994: Add missing NoC clocks") with ABI preservation.

An endpoint can be unregistered via two paths. Either its parent port is
unregistered, or the memdev that registered the endpoint is removed. The
memdev remove path is responsible for synchronizing against the parent
->remove() event and if the memdev remove path wins, manually trigger
unregister_port() via devm_release_action(). Until that race is resolved
the memdev remove path holds a reference on the endpoint.
If the parent port for the endpoint can not be found that is an
indication that the endpoint has already been registered. Be sure to
drop the reference in all exit paths from delete_endpoint().

Registers that belong to the shared render/compute reset domain need to
be placed on an engine workaround list to ensure that they are properly
re-applied whenever any RCS or CCS engine is reset, even if the
registers do not belong to a specific engine's MMIO range. We have a
number of workarounds today that are incorrectly implemented on the 'gt'
workaround list and need to be moved accordingly. We also have one
workaround (Wa_22012532006) that is incorrectly implemented on the
context workaround list, even though the register it is adjusting is not
part of the RCS engine's context image; it must also be moved.
We'll have some workaround refactoring coming in the near future that
deals with registers in the reset domain in a more clear way. But in
the meantime, we should just move these workarounds to
rcs_engine_wa_init() to place them on the RCS engine's workaround list.
All production DG2 platforms will have an RCS engine (it's never fused
off) so these registers will be properly restored after a domain reset
triggered via an RCS engine _or_ a CCS engine.

bpf_prog_pack_free() uses header->size to decide whether the header
should be freed with module_memfree() or the bpf_prog_pack logic.
However, in kvmalloc() failure path of bpf_jit_binary_pack_alloc(),
header->size is not set yet. As a result, bpf_prog_pack_free() may treat
a slice of a pack as a standalone kvmalloc'd header and call
module_memfree() on the whole pack. This in turn causes use-after-free by
other users of the pack.
Fix this by setting ro_header->size before freeing ro_header.

There is a logic error in the error handler's labels.
ex/ The sysfs: is the last goto label in the normal code but

cleanup: is the first error, so it's handler should be last.
interrupt: is the second error, it's handler is next. interrupt:
handles the failure of amdgpu_ras_interrupt_add_hander() by
calling amdgpu_ras_interrupt_remove_handler(). This is wrong,
remove() assumes the interrupt has been setup, not torn down by
add(). Change the goto label to cleanup.
sysfs is the last error, it's handler should be first. sysfs:
handles the failure of amdgpu_ras_sysfs_create() by calling
amdgpu_ras_sysfs_remove(). But when the create() fails there
is nothing added so there is nothing to remove. This error
handler is not needed. Remove the error handler and change

The `program_aspm` callback is already guarded for aspm, but the
`enable_aspm` callback doesn't follow the module parameter.
Update it to use the helper `amdgpu_device_should_use_aspm`.

Evaluating `pcie_aspm_enabled` as part of driver probe has the implication
that if one PCIe bridge with an AMD GPU connected doesn't support ASPM
then none of them do. This is an invalid assumption as the PCIe core will
configure ASPM for individual PCIe bridges.
Create a new helper function that can be called by individual dGPUs to
react to the `amdgpu_aspm` module parameter without having negative results
for other dGPUs on the PCIe bus.

commit 0064b0ce85bb ("drm/amd/pm: enable ASPM by default") enabled ASPM
by default but a variety of hardware configurations it turns out that this
caused a regression.
* PPC64LE hardware does not support ASPM at a hardware level.
CONFIG_PCIEASPM is often disabled on these architectures.
* Some dGPUs on ALD platforms don't work with ASPM enabled and PCIe subsystem
disables it
Check with the PCIe subsystem to see that ASPM has been enabled
or not.

1. Define amdgpu_ras_block_late_init_default in amdgpu_ras.c as
.ras_late_init common function, which is called when
.ras_late_init of ras block isn't initialized.
2. Remove the code of using amdgpu_ras_block_late_init to
initialize .ras_late_init in ras blocks.

1. Move calling ras block instance members from module internal
function to the top calling xxx_ras_late_init.
2. Module internal function calls can only use parameter variables
of xxx_ras_late_init instead of ras block instance members.

Yevhen Orlov says:
====================
net: marvell: prestera: add basic routes offloading
Add support for blackhole and local routes for Marvell Prestera driver.
Subscribe on fib notifications and handle add/del.
Add features:
- Support route adding.
e.g.: "ip route add blackhole 7.7.1.1/24"
e.g.: "ip route add local 9.9.9.9 dev sw1p30"
- Support "rt_trap", "rt_offload", "rt_offload_failed" flags
- Handle case, when route in "local" table overlaps route in "main" table
example:
ip ro add blackhole 7.7.7.7
ip ro add local 7.7.7.7 dev sw1p30
# blackhole route will be deoffloaded. rt_offload flag disappeared
Limitations:
- Only "blackhole" and "local" routes supported. "nexthop" routes is TRAP
for now and will be implemented soon.
- Only "local" and "main" tables supported

For now we support only TRAP or DROP, so we can offload only "local" or
"blackhole" routes.
Nexthop routes is TRAP for now. Will be implemented soon.
