Although most calls of scsi_device_put() happen from non-atomic context,
alua_rtpg_queue() calls this function from atomic context if
alua_rtpg_queue() itself is called from atomic context. alua_rtpg_queue()
is always called from contexts where the caller must hold at least one
reference to the scsi device in question. This means that the reference
taken by alua_rtpg_queue() itself can't be the last one, and thus can be
dropped without entering the code path in which scsi_device_put() might
actually sleep. Hence move the might_sleep() annotation from
scsi_device_put() into scsi_device_dev_release().

I'm not exactly clear on what strange workflow causes people to do it,
but clearly occasionally some files end up being committed as executable
even though they clearly aren't.
This is a reprise of commit 90fda63fa115 ("treewide: fix up files
incorrectly marked executable"), just with a different set of files (but
with the same trivial shell scripting).
So apparently we need to re-do this every five years or so, and Joe
needs to just keep reminding me to do so ;)

While looking through legacy platform data users, I noticed that
the DT probing never uses data from the DT properties, as the
platform_data structure gets overwritten directly after it
is initialized.
There have never been any boards defining the platform_data in
the mainline kernel either, so this driver so far only worked
with patched kernels or with the default values.
For the benefit of possible downstream users, fix the DT probe
by no longer overwriting the data.

It turns out the optimisation implemented by commit 4f2c3872dde5 is
totally broken, since all the places that consume hw->dtcs_used for
events other than cycle count are still not expecting it to be sparsely
populated, and fail to read all the relevant DTC counters correctly if
so.
If implemented correctly, the optimisation potentially saves up to 3
register reads per event update, which is reasonably significant for
events targeting a single node, but still not worth a massive amount of
additional code complexity overall. Getting it right within the current
design looks a fair bit more involved than it was ever intended to be,
so let's just make a functional revert which restores the old behaviour
while still backporting easily.

netif_stop_queue() and netif_wake_queue() act on TX queue 0. This is ok
as long as only a single TX queue is supported. But support for multiple
TX queues was introduced with 762031375d5c and I missed to adapt stop

Code inspection shows that both tg3_io_error_detected() and
tg3_reset_task() attempt to acquire the RTNL lock at the beginning of
their code blocks. If tg3_reset_task() should happen to execute between
the times when tg3_io_error_deteced() acquires the RTNL lock and
tg3_reset_task_cancel() is called, a deadlock will occur.
Moving tg3_reset_task_cancel() call earlier within the code block, prior
to acquiring RTNL, prevents this from happening, but also exposes another
deadlock issue where tg3_reset_task() may execute AFTER
tg3_io_error_detected() has executed:

The cxl_pmem.ko module houses the driver for both cxl_nvdimm_bridge
objects and cxl_nvdimm objects. When the core creates a cxl_nvdimm it
arranges for it to be autoremoved when the bridge goes down. However, if
the bridge never initialized because the cxl_pmem.ko module never
loaded, it sets up a the following crash scenario:
BUG: kernel NULL pointer dereference, address: 0000000000000478

It turns out the recent rework to simplify nvdimm probing obviated the
need to unregister cxl_nvdimm objects at cxl_nvdimm_bridge ->remove()
time. Leave the cxl_nvdimm device registered until the hosting
cxl_memdev departs. The alternative is that the cxl_memdev needs to be
reattached whenever the cxl_nvdimm_bridge attach state cycles, which is
awkward and unnecessary.
The only requirement is to make sure that when the cxl_nvdimm_bridge
goes away any dependent cxl_nvdimm objects are shutdown. Handle that in
unregister_nvdimm_bus().
With these registration entanglements removed there is no longer a need
to pre-load the cxl_pmem module in cxl_acpi.

struct bkey has internal padding in a union, but it isn't always named
the same (e.g. key ## _pad, key_p, etc). This makes it extremely hard
for the compiler to reason about the available size of copies done
against such keys. Use unsafe_memcpy() for now, to silence the many
run-time false positive warnings:

[Why&How]
Switching between certain modes that are freesync video modes and those
are not freesync video modes result in timing not changing as seen by
the monitor due to incorrect timing being driven.
The issue is fixed by ensuring that when a non freesync video mode is
set, we reset the freesync status on the crtc.

[Why]
amdgpu expects to update payload table for one stream one time
by calling dm_helpers_dp_mst_write_payload_allocation_table().
Currently, it get modified to try to update HW payload table
at once by referring mst_state.
[How]
This is just a quick workaround. Should find way to remove the
temporary struct dc_dp_mst_stream_allocation_table later if set
struct link_mst_stream_allocatio directly is possible.

Looks like I made a pretty big mistake here without noticing: it seems when
I moved the assignments of mst_state->pbn_div I completely missed the fact
that the reason for us calling drm_dp_mst_update_slots() earlier was to
account for the fact that we need to call this function using info from the
root MST connector, instead of just trying to do this from each MST
encoder's atomic check function. Otherwise, we end up filling out all of
DC's link information with zeroes.
So, let's restore that and hopefully fix this DSC regression.

Pull fuse ACL fix from Christian Brauner:
"The new posix acl API doesn't depend on the xattr handler
infrastructure anymore and instead only relies on the posix acl inode
operations. As a result daemons without FUSE_POSIX_ACL are unable to
use posix acls like they used to.
Fix this by copying what we did for overlayfs during the posix acl api
conversion. Make fuse implement a dedicated ->get_inode_acl() method
as does overlayfs. Fuse can then also uses this to express different
needs for vfs permission checking during lookup and acl based
retrieval via the regular system call path.
This allows fuse to continue to refuse retrieving posix acls for
daemons that don't set FUSE_POSXI_ACL for permission checking while
also allowing a fuse server to retrieve it via the usual system calls"

If "capacity-dmips-mhz" is present in a CPU DT node,
topology_parse_cpu_capacity() will fail to allocate memory. arm64, with
which this code path is shared, does not call
topology_parse_cpu_capacity() until later in boot where memory
allocation is available. While "capacity-dmips-mhz" is not yet a valid
property on RISC-V, invalid properties should be ignored rather than
cause issues. Move init_cpu_topology(), which calls
topology_parse_cpu_capacity(), to a later initialization stage, to match
arm64.
As a side effect of this change, RISC-V is "protected" from changes to
core topology code that would work on arm64 where memory allocation is
safe but on RISC-V isn't.

Once a socket has been unhashed, we want to prevent it from being
re-used in a sk_key entry as part of a routing operation.
This change marks the sk as SOCK_DEAD on unhash, which prevents addition
into the net's key list.
We need to do this during the key add path, rather than key lookup, as
we release the net keys_lock between those operations.

Currently, we have a race where we look up a sock through a "general"
(ie, not directly associated with the (src,dest,tag) tuple) key, then
drop the key reference while still holding the key's sock.
This change expands the key reference until we've finished using the
sock, and hence the sock reference too.

Currently, we delete the key expiry timer (in sk->close) before
unhashing the sk. This means that another thread may find the sk through
its presence on the key list, and re-queue the timer.
This change moves the timer deletion to the unhash, after we have made
the key no longer observable, so the timer cannot be re-queued.

Currently, we correlate the mctp_sk_key lifetime to the sock lifetime
through the sock hash/unhash operations, but this is pretty tenuous, and
there are cases where we may have a temporary reference to an unhashed
sk.
This change makes the reference more explicit, by adding a hold on the
sock when it's associated with a mctp_sk_key, released on final key
unref.
