stmmac_check_ether_addr() checks the MAC address and assigns one in
driver open(). In many cases when we create slave netdevice, the dev
addr is inherited from master but the master dev addr maybe NULL at
that time, so move this call to driver probe so that address is
always valid.

When a blocked NFS lock is "awoken" we send a callback to the server and
then wake any hosts waiting on it. If a client attempts to get a lock
and then drops off the net, we could end up waiting for a long time
until we end up waking locks blocked on that request.
So, wake any other waiting lock requests before sending the callback.
Do this by calling locks_delete_block in a new "prepare" phase for
CB_NOTIFY_LOCK callbacks.

After a blocked nfsd file_lock request is deleted, knfsd will send a
callback to the client and then free the request. Commit 16306a61d3
("fs/locks: always delete_block after waiting.") changed it such that
locks_delete_block is always called on a request after it is awoken,
but that patch missed fixing up blocked nfsd request handling.
Call locks_delete_block on the block to wake up any locks still blocked
on the nfsd lock request before freeing it. Some of its callers already
do this however, so just remove those calls.

If we have multiple threads doing io_uring_register(2) on an io_uring

Prevent this race by failing io_uring_register(2) if the ref is marked

The original intention to move RDSP parsing very early, before KASLR
does its ranges selection, was to accommodate movable memory regions
machines (CONFIG_MEMORY_HOTREMOVE) to still be able to do memory
hotplug.
However, that broke kexec'ing a kernel on EFI machines because depending
on where the EFI systab was mapped, on at least one machine it isn't
present in the kexec mapping of the second kernel, leading to a triple
fault in the early code.
Fixing this properly requires significantly involved surgery and we
cannot allow ourselves to do that, that close to the merge window.
So disable the RSDP parsing code temporarily until it is fixed properly
in the next release cycle.

setting net.netfilter.nf_conntrack_timestamp=1 breaks xmit with fq
scheduler. skb->tstamp might be "refreshed" using ktime_get_real(),
but fq expects CLOCK_MONOTONIC.
This patch removes all places in netfilter that check/set skb->tstamp:
1. To fix the bogus "start" time seen with conntrack timestamping for
outgoing packets, never use skb->tstamp and always use current time.
2. In nfqueue and nflog, only use skb->tstamp for incoming packets,
as determined by current hook (prerouting, input, forward).
3. xt_time has to use system clock as well rather than skb->tstamp.
We could still use skb->tstamp for prerouting/input/foward, but
I see no advantage to make this conditional.

So we are going to be staring at those in the next years, let's make
them more succinct. In particular:
- change "address = " to "address: "
- "-privileged" reads funny. It should be simply "kernel" or "user"
- "from kernel code" reads funny too. "kernel mode" or "user mode" is
more natural.

When device refuses the offload in tls_set_device_offload_rx()
it calls tls_sw_free_resources_rx() to clean up software context
state.
Unfortunately, tls_sw_free_resources_rx() does not free all
the state tls_set_sw_offload() allocated - it leaks IV and
sequence number buffers. All other code paths which lead to
tls_sw_release_resources_rx() (which tls_sw_free_resources_rx()
calls) free those right before the call.
Avoid the leak by moving freeing of iv and rec_seq into
tls_sw_release_resources_rx().

If we add a bond device which is already the master of the team interface,
we will hold the team->lock in team_add_slave() first and then request the
lock in team_set_mac_address() again. The functions are called like:
- team_add_slave()
- team_port_add()
- team_port_enter()
- team_modeop_port_enter()
- __set_port_dev_addr()
- dev_set_mac_address()
- bond_set_mac_address()
- dev_set_mac_address()
- team_set_mac_address
Although team_upper_dev_link() would check the upper devices but it is
called too late. Fix it by adding a checking before processing the slave.

xdp_return_frame releases the frame. It leads to releasing the page, so

reported.
The vt one has been around for a while, it is good to finally get that

resolve a problem in the sh-sci driver.
Note, the second patch for build warning fix for the sc16is7xx driver
was just applied to the tree, as it resolves a problem with the previous

unlike all of the other patches, but it has passed 0-day testing and

I've discovered following discrepancy in the bindings/net/ethernet.txt
documentation, where it states following:
- nvmem-cells: phandle, reference to an nvmem node for the MAC address;
- nvmem-cell-names: string, should be "mac-address" if nvmem is to be..
which is actually misleading and confusing. There are only two ethernet
drivers in the tree, cadence/macb and davinci which supports this
properties.
This nvmem-cell* properties were introduced in commit 9217e566bd
("of_net: Implement of_get_nvmem_mac_address helper"), but
commit afa64a72b8 ("of: net: kill of_get_nvmem_mac_address()")
forget to properly clean up this parts.
So this patch fixes the documentation by moving the nvmem-cell*
properties at the appropriate places. While at it, I've removed unused
include as well.

bvec->bv_offset may be bigger than PAGE_SIZE sometimes, such as,
when one bio is splitted in the middle of one bvec via bio_split(),
and bi_iter.bi_bvec_done is used to build offset of the 1st bvec of
remained bio. And the remained bio's bvec may be re-submitted to fs
layer via ITER_IBVEC, such as loop and nvme-loop.
So we have to make sure that every bvec's offset is less than
PAGE_SIZE from bio_for_each_segment_all() because some drivers(loop,
nvme-loop) passes the splitted bvec to fs layer via ITER_BVEC.
This patch fixes this issue reported by Zhang Yi When running nvme/011.

Linus pointed out that deciphering the raw #PF error code and printing
a more human readable message are two different things, and also that
printing the negative cases is mostly just noise[1]. For example, the
USER bit doesn't mean the fault originated in user code and stating
that an oops wasn't due to a protection keys violation isn't interesting
since an oops on a keys violation is a one-in-a-million scenario.
Remove the per-bit decoding of the error code and instead print:
- the raw error code
- why the fault occurred
- the effective privilege level of the access
- the type of access
- whether the fault originated in user code or kernel code
This provides the user with the information needed to triage 99.9% of
oopses without polluting the log with useless information or conflating
the error_code with the CPL.
Sample output:
BUG: kernel NULL pointer dereference, address = 0000000000000008
#PF: supervisor-privileged instruction fetch from kernel code
#PF: error_code(0x0010) - not-present page
BUG: unable to handle page fault for address = ffffbeef00000000
#PF: supervisor-privileged instruction fetch from kernel code
#PF: error_code(0x0010) - not-present page
BUG: unable to handle page fault for address = ffffc90000230000
#PF: supervisor-privileged write access from kernel code
#PF: error_code(0x000b) - reserved bit violation

Reword the NULL pointer dereference case to simply state that a NULL
pointer was dereferenced, i.e. drop "unable to handle" as that implies
that there are instances where the kernel actual does handle NULL
pointer dereferences, which is not true barring funky exception fixup.
For the non-NULL case, replace "kernel paging request" with "page fault"
as the kernel can technically oops on faults that originated in user
code. Dropping "kernel" also allows future patches to provide detailed
information on where the fault occurred, e.g. user vs. kernel, without
conflicting with the initial BUG message.
In both cases, replace "at address=" with wording more appropriate to
the oops, as "at" may be interpreted as stating that the address is the
RIP of the instruction that faulted.
Last, and probably least, further qualify the NULL-pointer path by
checking that the fault actually originated in kernel code. It's
technically possible for userspace to map address 0, and not printing
a super specific message is the least of our worries if the kernel does
manage to oops on an actual NULL pointer dereference from userspace.
Before:
BUG: unable to handle kernel NULL pointer dereference at ffffbeef00000000
BUG: unable to handle kernel paging request at ffffbeef00000000
After:
BUG: kernel NULL pointer dereference, address = 0000000000000008
BUG: unable to handle page fault for address = ffffbeef00000000
