Pull cachefiles and afs fixes from David Howells:
"Fixes from Matthew Wilcox for page waiting-related issues in
cachefiles and afs as extracted from his folio series[1]:
- In cachefiles, remove the use of the wait_bit_key struct to access
something that's actually in wait_page_key format. The proper
struct is now available in the header, so that should be used
instead.
- Add a proper wait function for waiting killably on the page
writeback flag. This includes a recent bugfix[2] that's not in the
afs code.
- In afs, use the function added in (2) rather than using
wait_on_page_bit_killable() which doesn't provide the

As explained in this discussion:
https://lore.kernel.org/netdev/20210117193009.io3nungdwuzmo5f7@skbuf/
the switchdev notifiers for FDB entries managed to have a zero-day bug.
The bridge would not say that this entry is local:
ip link add br0 type bridge
ip link set swp0 master br0
bridge fdb add dev swp0 00:01:02:03:04:05 master local
and the switchdev driver would be more than happy to offload it as a
normal static FDB entry. This is despite the fact that 'local' and
non-'local' entries have completely opposite directions: a local entry
is locally terminated and not forwarded, whereas a static entry is
forwarded and not locally terminated. So, for example, DSA would install
this entry on swp0 instead of installing it on the CPU port as it should.
There is an even sadder part, which is that the 'local' flag is implicit
if 'static' is not specified, meaning that this command produces the
same result of adding a 'local' entry:
bridge fdb add dev swp0 00:01:02:03:04:05 master
I've updated the man pages for 'bridge', and after reading it now, it
should be pretty clear to any user that the commands above were broken
and should have never resulted in the 00:01:02:03:04:05 address being
forwarded (this behavior is coherent with non-switchdev interfaces):
https://patchwork.kernel.org/project/netdevbpf/cover/20210211104502.2081443-1-olteanv@gmail.com/
If you're a user reading this and this is what you want, just use:
bridge fdb add dev swp0 00:01:02:03:04:05 master static
Because switchdev should have given drivers the means from day one to
classify FDB entries as local/non-local, but didn't, it means that all
drivers are currently broken. So we can just as well omit the switchdev
notifications for local FDB entries, which is exactly what this patch
does to close the bug in stable trees. For further development work
where drivers might want to trap the local FDB entries to the host, we
can add a 'bool is_local' to br_switchdev_fdb_call_notifiers(), and
selectively make drivers act upon that bit, while all the others ignore
those entries if the 'is_local' bit is set.

Invalid detection works with two distinct moments: act_ct tries to find
a conntrack entry and set post_ct true, indicating that that was
attempted. Then, when flow dissector tries to dissect CT info and no
entry is there, it knows that it was tried and no entry was found, and
synthesizes/sets
key->ct_state = TCA_FLOWER_KEY_CT_FLAGS_TRACKED |
TCA_FLOWER_KEY_CT_FLAGS_INVALID;
mimicing what OVS does.
OVS has this a bit more streamlined, as it recomputes the key after
trying to find a conntrack entry for it.
Issue here is, when we have 'tc action ct clear', it didn't clear
post_ct, causing a subsequent match on 'ct_state -trk' to fail, due to
the above. The fix, thus, is to clear it.
Reproducer rules:
tc filter add dev enp130s0f0np0_0 ingress prio 1 chain 0 \
protocol ip flower ip_proto tcp ct_state -trk \
action ct zone 1 pipe \
action goto chain 2
tc filter add dev enp130s0f0np0_0 ingress prio 1 chain 2 \
protocol ip flower \
action ct clear pipe \
action goto chain 4
tc filter add dev enp130s0f0np0_0 ingress prio 1 chain 4 \
protocol ip flower ct_state -trk \
action mirred egress redirect dev enp130s0f1np1_0
With the fix, the 3rd rule matches, like it does with OVS kernel
datapath.

Due to a HW limitation, the Latency Tolerance Reporting (LTR) value
programmed in the Tiger Lake GBE controller is not large enough to allow
the platform to enter Package C10, which in turn prevents the platform from
achieving its low power target during suspend-to-idle. Ignore the GBE LTR
value on Tiger Lake. LTR ignore functionality is currently performed solely
by a debugfs write call. Split out the LTR code into its own function that
can be called by both the debugfs writer and by this work around.

Device firmware doesn't handle ecpu bit for vhca state processing
events and commands. Instead device firmware refers to the unique
function id to distinguish SF of different PCI functions.
When ecpu bit is used, firmware returns a syndrome.
mlx5_cmd_check:780:(pid 872): MODIFY_VHCA_STATE(0xb0e) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x263211)
mlx5_sf_dev_table_create:248:(pid 872): SF DEV table create err = -22
Hence, avoid using ecpu bit.

mlx5e_select_queue compares num_tc_x_num_ch to real_num_tx_queues to
determine if HTB and/or PTP offloads are active. If they are, it
calculates netdev_pick_tx() % num_tc_x_num_ch to prevent it from
selecting HTB and PTP queues for regular traffic. However, before the
channels are first activated, num_tc_x_num_ch is zero. If
ndo_select_queue gets called at this point, the HTB/PTP check will pass,
and mlx5e_select_queue will attempt to take a modulo by num_tc_x_num_ch,
which equals to zero.
This commit fixes the bug by assigning num_tc_x_num_ch to a non-zero
value before registering the netdev.

Setting connection tracking OVS flows and then setting non-CT flows that
use tuple rewrite action (e.g. mod_tp_dst), causes the latter flows not
being offloaded.
Fix by using a stricter condition in modify_header_match_supported() to
check tuple rewrite support only for flows with CT action. The check is
factored out into standalone modify_tuple_supported() function to aid
readability.

Currently, we support hardware offload only for MPLS over UDP.
However, rules matching on MPLS parameters are now wrongly offloaded
for regular MPLS, without actually taking the parameters into
consideration when doing the offload.
Fix it by rejecting such unsupported rules.

ic_close_dev contains a generalization of the logic to not close a
network interface if it's the host port for a DSA switch. This logic is
disguised behind an iteration through the lowers of ic_dev in
ic_close_dev.
When no interface for ipconfig can be found, ic_dev is NULL, and
ic_close_dev:
- dereferences a NULL pointer when assigning selected_dev
- would attempt to search through the lower interfaces of a NULL
net_device pointer
So we should protect against that case.
The "lower_dev" iterator variable was shortened to "lower" in order to
keep the 80 character limit.

Pull x86 fixes from Borislav Petkov:
"The freshest pile of shiny x86 fixes for 5.12:
- Add the arch-specific mapping between physical and logical CPUs to
fix devicetree-node lookups
- Restore the IRQ2 ignore logic
- Fix get_nr_restart_syscall() to return the correct restart syscall
number. Split in a 4-patches set to avoid kABI breakage when
backporting to dead kernels"

Thanks to Christophe Leroy and Tyrel Datwyler.

Stop reporting SW_DOCK events because this breaks suspend-on-lid-close.
SW_DOCK should only be reported for docking stations, but all the DSDTs in
my DSDT collection which use the intel-vbtn code, always seem to use this
for 2-in-1s / convertibles and set SW_DOCK=1 when in laptop-mode (in tandem
with setting SW_TABLET_MODE=0).
This causes userspace to think the laptop is docked to a port-replicator
and to disable suspend-on-lid-close, which is undesirable.
Map the dock events to KEY_IGNORE to avoid this broken SW_DOCK reporting.
Note this may theoretically cause us to stop reporting SW_DOCK on some
device where the 0xCA and 0xCB intel-vbtn events are actually used for
reporting docking to a classic docking-station / port-replicator but
I'm not aware of any such devices.
Also the most important thing is that we only report SW_DOCK when it
reliably reports being docked to a classic docking-station without any
false positives, which clearly is not the case here. If there is a
chance of reporting false positives then it is better to not report
SW_DOCK at all.

Cleanup create_attributes_level_sysfs_files():
1. There is no need to call sysfs_remove_file() on error, sysman_init()
will already call release_attributes_data() on failure which already does
this.
2. There is no need for the pr_debug() calls sysfs_create_file() should
never fail and if it does it will already complain about the problem
itself.

Cleanup sysman_init() error-exit handling:
1. There is no need for the fail_reset_bios and fail_authentication_kset
eror-exit cases, these can be handled by release_attributes_data()
2. Rename all the labels from fail_what_failed, to err_what_to_cleanup
this is the usual way to name these and avoids the need to rename
them when extra steps are added.

All calls of init_bios_attributes() will result in a
goto fail_create_group if they fail, which calls
release_attributes_data().
So there is no need to call release_attributes_data() from
init_bios_attributes() on failure itself.

During some of the error-exit paths it is possible that
release_attributes_data() will get called multiple times,
which results in exit_foo_attributes() getting called multiple
times.
Make it safe to call exit_foo_attributes() multiple times,
avoiding double-free()s in this case.
Note that release_attributes_data() really should only be called
once during error-exit paths. This will be fixed in a separate patch
and it is good to have the exit_foo_attributes() functions modified
this way regardless.

It is possible for release_attributes_data() to get called when the
main_dir_kset has not been created yet, move the removal of the bios-reset
sysfs attr to under a if (main_dir_kset) check to avoid a NULL pointer
deref.
