Currently, when cross compiling bpf samples, the host side cannot
use arch-specific bpftool to generate vmlinux.h or skeleton. Since
samples/bpf use bpftool for vmlinux.h, skeleton, and static linking
only, we can use lightweight bootstrap version of bpftool to handle
these, and it's always host-native.

After commit 62b36c3ea664 ("PCI/AER: Remove
pci_cleanup_aer_uncorrect_error_status() calls"), calls to
pci_cleanup_aer_uncorrect_error_status() have already been removed. But in
commit 5995b6d0c6fc ("ice: Implement pci_error_handler ops")
pci_cleanup_aer_uncorrect_error_status was used again, so remove it in
this patch.

Revert the xarray conversion, there's a problem with potential
sleep-inside-spinlock [1] when calling xa_insert that triggers GFP_NOFS
allocation. The radix tree used the preloading mechanism to avoid

Instead of doing complicated calculations to find the size of the subroutines
(which are even more complicated because they need to be stringified into
an asm statement), just hardcode to 16.
It is less dense for a few combinations of IBT/SLS/retbleed, but it has
the advantage of being really simple.

and invoke mediatek_dwmac_clks_config() instead.
2. update commit message.

Current stmmac driver will prepare/enable ptp_ref clock in
stmmac_init_tstamp_counter().
The stmmac_pltfr_noirq_suspend will disable it once in suspend flow.
But in resume flow,
stmmac_pltfr_noirq_resume --> stmmac_init_tstamp_counter
stmmac_resume --> stmmac_hw_setup --> stmmac_init_ptp --> stmmac_init_tstamp_counter
ptp_ref clock reference counter increases twice, which leads to unbalance
ptp clock when resume back.
Move ptp_ref clock prepare/enable out of stmmac_init_tstamp_counter to fix it.

If netif is running when stmmac_dvr_remove is invoked,
the unregister_netdev will call ndo_stop(stmmac_release) and
vlan_kill_rx_filter(stmmac_vlan_rx_kill_vid).
Currently, stmmac_dvr_remove() will disable pm runtime before
unregister_netdev. When stmmac_vlan_rx_kill_vid is invoked,
pm_runtime_resume_and_get in it returns EACCESS error number,
and reports:

The pm_runtime takes care of the clock handling in current
stmmac drivers, and dwmac-mediatek implement the
mediatek_dwmac_clks_config() as the callback for pm_runtime.
Then, stripping duplicated clocks handling in old init()/exit()
to fix clock issue in suspend/resume test.
As to clocks in probe/remove, vendor need symmetric handling to
ensure clocks balance.
Test pass, including suspend/resume and ko insertion/remove.

sysctl: Fix data-races around ipv4_net_table (Round 2).
This series fixes data-races around 15 knobs after ip_default_ttl in
ipv4_net_table.
These two knobs are skipped.
- ip_local_port_range is safe with its own lock.
- ip_local_reserved_ports uses proc_do_large_bitmap(), which will need
an additional lock and can be fixed later.
So, the next round will start with igmp_link_local_mcast_reports.

The console_stop() and console_start() functions call pr_flush().
When suspending, these functions are called by the serial subsystem
while the serial port is suspended. In this scenario, if there are
any pending messages, a call to pr_flush() will always result in a
timeout because the serial port cannot make forward progress. This
causes longer suspend and resume times.
Add a check in pr_flush() so that it will immediately timeout if
the consoles are suspended.
Fixes: 3b604ca81202 ("printk: add pr_flush()")

The commit 7337224fc150 ("bpf: Improve the info.func_info and info.func_info_rec_size behavior")
accidently made bpf_prog_ksym_set_name() conservative for bpf subprograms.
Fixed it so instead of "bpf_prog_tag_F" the stack traces print "bpf_prog_tag_full_subprog_name".

Alexei reported crash by running test_progs -j on system
with 32 cpus.
It turned out the kprobe_multi bench test that attaches all
ftrace-able functions will race with bpf_dispatcher_update,
that calls bpf_arch_text_poke on bpf_dispatcher_xdp_func,
which is ftrace-able function.
Ftrace is not aware of this update so this will cause
ftrace_bug with:
WARNING: CPU: 6 PID: 1985 at

Setting ftrace call site to call ftrace function
It looks like we need some way to hide some functions
from ftrace, but meanwhile we workaround this by skipping
bpf_dispatcher_xdp_func from kprobe_multi bench test.

Saeed Mahameed says:
====================
mlx5-updates-2022-07-13
1) Support 802.1ad for bridge offloads
Vlad Buslov Says:
=================
Current mlx5 bridge VLAN offload implementation only supports 802.1Q VLAN
Ethernet protocol. That protocol type is assumed by default and
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL notification is ignored.
In order to support dynamically setting VLAN protocol handle
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL notification by flushing FDB and
re-creating VLAN modify header actions with a new protocol. Implement support
for 802.1ad protocol by saving the current VLAN protocol to per-bridge variable
and re-create the necessary flow groups according to its current value (either
use cvlan or svlan flow fields).
==================
2) debugfs to count ongoing FW commands
3) debugfs to query eswitch vport firmware diagnostic counters
4) Add missing meter configuration in flow action
5) Some misc cleanup
* tag 'mlx5-updates-2022-07-13' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux:
net/mlx5e: Remove the duplicating check for striding RQ when enabling LRO
net/mlx5e: Move the LRO-XSK check to mlx5e_fix_features
net/mlx5e: Extend flower police validation
net/mlx5e: configure meter in flow action
net/mlx5e: Removed useless code in function
net/mlx5: Bridge, implement QinQ support
net/mlx5: Bridge, implement infrastructure for VLAN protocol change
net/mlx5: Bridge, extract VLAN push/pop actions creation
net/mlx5: Bridge, rename filter fg to vlan_filter
net/mlx5: Bridge, refactor groups sizes and indices
net/mlx5: debugfs, Add num of in-use FW command interface slots
net/mlx5: Expose vnic diagnostic counters for eswitch managed vports
net/mlx5: Use software VHCA id when it's supported
net/mlx5: Introduce ifc bits for using software vhca id
net/mlx5: Use the bitmap API to allocate bitmaps

The AP bus's __verify_queue_reservations function increments the ref count
for the device driver passed in as a parameter, but fails to decrement it
before returning control to the caller. This will prevents any subsequent
removal of the module.
