Functions called by the netevent notifier must be in atomic context.
Change the mutex to spinlock and ensure mem allocations are done with the
atomic flag.
Also, remove unnecessary locking after notifiers are unregistered.

LiquidIO firmware supports a vswitch that needs to know the names of the
VF representors in the host to maintain compatibility for direct
programming using external Openflow agents. So, for each VF representor,
send its name to the firmware when it gets registered and when its name
changes.

Two minor cleanups after Dave's recent merge in f8ddadc4db6c
("Merge git://git.kernel.org...") of net into net-next in
order to get the code in line with what was done originally
in the net tree: i) use max() instead of max_t() since both
ranges are u16, ii) don't split the direct access test cases
in the middle with bpf_exit test cases from 390ee7e29fc

Compilers are starting to use BPF_NEG, for example LLVM. However, NFP

Currently the bridge device doesn't generate any notifications upon vlan
modifications on itself because it doesn't use the generic bridge
notifications.
With the recent changes we know if anything was modified in the vlan config
thus we can generate a notification when necessary for the bridge device
so add support to br_ifinfo_notify() similar to how other combined
functions are done - if port is present it takes precedence, otherwise
notify about the bridge. I've explicitly marked the locations where the
notification should be always for the port by setting bridge to NULL.
I've also taken the liberty to rearrange each modified function's local
variables in reverse xmas tree as well.

r0 = userfaultfd(0x0)

r1 = gettid()
syz_open_dev$evdev(&(0x7f0000013000-0x12)="2f6465762f696e7075742f6576656e742300", 0x0, 0x0)
tkill(r1, 0x7)
The vma should be pinned by mmap_sem, but handle_userfault() might (in a
return to userspace scenario) release it and then acquire again, so when
we return to __do_page_fault() (with other result than VM_FAULT_RETRY),
the vma might be gone.
Specifically, per Andrea the scenario is
"A return to userland to repeat the page fault later with a
VM_FAULT_NOPAGE retval (potentially after handling any pending signal
during the return to userland). The return to userland is identified
whenever FAULT_FLAG_USER|FAULT_FLAG_KILLABLE are both set in
vmf->flags"
However, since commit a3c4fb7c9c2e ("x86/mm: Fix fault error path using
unsafe vma pointer") there is a vma_pkey() read of vma->vm_flags after
that point, which can thus become use-after-free. Fix this by moving
the read before calling handle_mm_fault().

cxgb4: add hash-filter support to tc-flower offload
This series of patches add support to create hash-filters; a.k.a
exact-match filters, to tc-flower offload. T6 supports creating
~500K hash-filters in hw and can theoretically be expanded up to
~1 million.
Patch 1 fetches and saves the configured hw filter tuple field shifts
and filter mask.
Patch 2 initializes the driver to use hash-filter configuration.
Patch 3 adds support to create hash filters in hw.
Patch 4 adds support to delete hash filters in hw.
Patch 5 adds support to retrieve filter stats for hash filters.
Patch 6 converts the flower table to use rhashtable instead of
static hlist.
Patch 7 finally adds support to create hash filters via tc-flower
offload.
