The register and range mappings for the PCIe controller in Rockchip's
RK356x SoCs are incorrect. Replace them with corrected values from the
vendor BSP sources, updated to match current DT schema.
These values are also used in u-boot.

The DSPI controller has configurable timing for
(a) tCSC: the interval between the assertion of the chip select and the
first clock edge
(b) tASC: the interval between the last clock edge and the deassertion
of the chip select
What is a bit surprising, but is documented in the figure "Example of
continuous transfer (CPHA=1, CONT=1)" in the datasheet, is that when the
chip select stays asserted between multiple TX FIFO writes, the tCSC and
tASC times still apply. With CONT=1, chip select remains asserted, but
SCK takes a break and goes to the idle state for tASC + tCSC ns.
In other words, the default values (of 0 and 0 ns) result in SCK
glitches where the SCK transition to the idle state, as well as the SCK
transition from the idle state, will have no delay in between, and it
may appear that a SCK cycle has simply gone missing. The resulting
timing violation might cause data corruption in many peripherals, as
their chip select is asserted.
The driver has device tree bindings for tCSC ("fsl,spi-cs-sck-delay")
and tASC ("fsl,spi-sck-cs-delay"), but these are only specified to apply
when the chip select toggles in the first place, and this timing
characteristic depends on each peripheral. Many peripherals do not have
explicit timing requirements, so many device trees do not have these
properties present at all.
Nonetheless, the lack of SCK glitches is a common sense requirement, and
since the SCK stays in the idle state during transfers for tCSC+tASC ns,
and that in itself should look like half a cycle, then let's ensure that
tCSC and tASC are at least a quarter of a SCK period, such that their
sum is at least half of one.

When constructing the sim, gpio-sim constructs an array of named lines,
sized based on the largest offset of any named line, and then initializes
that array with the names of all lines, including unnamed hogs with higher
offsets. In doing so it writes NULLs beyond the extent of the array.
Add a check that only named lines are used to initialize the array.

kmemdup() at line 2735 is not duplicating enough memory for
notif->tid_tear_down and notif->station_id. As it only duplicates
612 bytes: up to offsetofend(struct iwl_wowlan_info_notif,
received_beacons), this is the range of [0, 612) bytes.
2735 notif = kmemdup(notif_v1,
2736 offsetofend(struct iwl_wowlan_info_notif,
2737 received_beacons),
2738 GFP_ATOMIC);
which evidently does not cover bytes 612 and 613 for members
tid_tear_down and station_id in struct iwl_wowlan_info_notif.
See below:
$ pahole -C iwl_wowlan_info_notif drivers/net/wireless/intel/iwlwifi/mvm/d3.o
struct iwl_wowlan_info_notif {
struct iwl_wowlan_gtk_status_v3 gtk[2]; /* 0 488 */

Therefore, when the following assignments take place, actually no memory

Fix this by allocating space for the whole notif object and zero out the

This also fixes the following -Warray-bounds issues:

Currently, whenever an EMA beacon is formed, due to is_template
argument being false from the caller, the switch count is always
decremented once which is wrong.
Also if switch count is equal to profile periodicity, this makes
the switch count to reach till zero which triggers a WARN_ON_ONCE.

There were two bugs when creating the non-inheritence
element:
1) 'at_extension' needs to be declared outside the loop,
otherwise the value resets every iteration and we
can never really switch properly
2) 'added' never got set to true, so we always cut off
the extension element again at the end of the function
This shows another issue that we might add a list but no
extension list, but we need to make the extension list a
zero-length one in that case.
Fix all these issues. While at it, add a comment explaining
the trim.

Move capturing the snapshot context into the image request state
machine, after exclusive lock is ensured to be held for the duration of
dealing with the image request. This is needed to ensure correctness
of fast-diff states (OBJECT_EXISTS vs OBJECT_EXISTS_CLEAN) and object
deltas computed based off of them. Otherwise the object map that is
forked for the snapshot isn't guaranteed to accurately reflect the
contents of the snapshot when the snapshot is taken under I/O. This
breaks differential backup and snapshot-based mirroring use cases with
fast-diff enabled: since some object deltas may be incomplete, the
destination image may get corrupted.

L2CAP assumes that the locks conn->chan_lock and chan->lock are
acquired in the order conn->chan_lock, chan->lock to avoid
potential deadlock.
For example, l2sock_shutdown acquires these locks in the order:
mutex_lock(&conn->chan_lock)
l2cap_chan_lock(chan)
However, l2cap_disconnect_req acquires chan->lock in
l2cap_get_chan_by_scid first and then acquires conn->chan_lock
before calling l2cap_chan_del. This means that these locks are
acquired in unexpected order, which leads to potential deadlock:
l2cap_chan_lock(c)
mutex_lock(&conn->chan_lock)
This patch releases chan->lock before acquiring the conn_chan_lock
to avoid the potential deadlock.

The existing documentation refers to memory.high as the "main mechanism
to control memory usage." This seems incorrect to me - memory.high can
result in reclaim pressure which simply leads to stalls unless some
external component observes and actions on it (e.g. systemd-oomd can be
used for this purpose). While this is feasible, users are unaware of
this interaction and are led to believe that memory.high alone is an
effective mechanism for limiting memory.
The documentation should recommend the use of memory.max as the
effective way to enforce memory limits - it triggers reclaim and results
in OOM kills by itself.

bpf_attach_type. And wire all that properly throughout the kernel and

[CAUSE]
In btrfs/027 we test RAID6 with missing devices, in this particular
case, we're repairing a metadata at the end of a data stripe.
But at btrfs_repair_io_failure(), we always pass a full PAGE for repair,
and for subpage case this can cross stripe boundary and lead to the
above BUG_ON().
This metadata repair code is always there, since the introduction of
subpage support, but this can trigger BUG_ON() after the bio split
ability at btrfs_map_bio().
[FIX]
Instead of passing the old PAGE_SIZE, we calculate the correct length
based on the eb size and page size for both regular and subpage cases.
