A long time ago the kmap_atomic API required a slot to be provided which
risked the possibility that other code might use the same slot at the
same time. Disabling interrupts prevented the possibility of an interrupt
handler doing that. However, that went away with
commit 3e4d3af501cc ("mm: stack based kmap_atomic()").
When the second argument to kmap_atomic was removed by commit 482fce997e14
("mmc: remove the second argument of k[un]map_atomic()"),
local_irq_{save,restore}() should have been removed also.
Remove it now.

kmap_local_page() is equivalent to kmap_atomic() except that it does not
disable page faults or preemption. Where possible kmap_local_page() is
preferred to kmap_atomic() - refer kernel highmem documentation.
In this case, there is no need to disable page faults or preemption, so
replace kmap_atomic() with kmap_local_page(), and, correspondingly,
kunmap_atomic() with kunmap_local().

sg_copy_{from,to}_buffer()

When sending packets between nodes in netns, it calls tipc_lxc_xmit() for
peer node to receive the packets where tipc_sk_mcast_rcv()/tipc_sk_rcv()
might be called, and it's pretty much like in tipc_rcv().
Currently the local 'node rw lock' is held during calling tipc_lxc_xmit()
to protect the peer_net not being freed by another thread. However, when
receiving these packets, tipc_node_add_conn() might be called where the
peer 'node rw lock' is acquired. Then a dead lock warning is triggered by
lockdep detector, although it is not a real dead lock:

This patch avoids this warning by not holding the 'node rw lock' before
calling tipc_lxc_xmit(). As to protect the 'peer_net', rcu_read_lock()
should be enough, as in cleanup_net() when freeing the netns, it calls
synchronize_rcu() before the free is continued.
Also since tipc_lxc_xmit() is like the RX path in tipc_rcv(), it makes
sense to call it under rcu_read_lock(). Note that the right lock order
must be:
rcu_read_lock();
tipc_node_read_lock(n);
tipc_node_read_unlock(n);
tipc_lxc_xmit();
rcu_read_unlock();
instead of:
tipc_node_read_lock(n);
rcu_read_lock();
tipc_node_read_unlock(n);
tipc_lxc_xmit();
rcu_read_unlock();
and we have to call tipc_node_read_lock/unlock() twice in
tipc_node_xmit().

We don't get any further EVENT from an esd CAN USB device for changes
on REC or TEC while those counters converge to 0 (with ecc == 0). So
when handling the "Back to Error Active"-event force txerr = rxerr =
0, otherwise the berr-counters might stay on values like 95 forever.
Also, to make life easier during the ongoing development a
netdev_dbg() has been introduced to allow dumping error events send by
an esd CAN USB device.

Apparently, the slcan's tx_work is freed while being scheduled. While
slcan_netdev_close() (netdev side) calls flush_work(&sl->tx_work),
slcan_close() (tty side) does not. So when the netdev is never set UP,
but the tty is stuffed with bytes and forced to wakeup write, the work
is scheduled, but never flushed.
So add an additional flush_work() to slcan_close() to be sure the work
is flushed under all circumstances.
The Fixes commit below moved flush_work() from slcan_close() to
slcan_netdev_close(). What was the rationale behind it? Maybe we can
drop the one in slcan_netdev_close()?
I see the same pattern in can327. So it perhaps needs the very same fix.

Analogue to commit 8aa59e355949 ("can: af_can: fix NULL pointer
dereference in can_rx_register()") we need to check for a missing
initialization of ml_priv in the receive path of CAN frames.
Since commit 4e096a18867a ("net: introduce CAN specific pointer in the
struct net_device") the check for dev->type to be ARPHRD_CAN is not
sufficient anymore since bonding or tun netdevices claim to be CAN
devices but do not initialize ml_priv accordingly.

Ido Schimmel says:
====================
ipv4: Two small fixes for bugs in IPv4 routing code.
A variation of the second bug was reported by an FRR 5.0 (released
06/18) user as this version was setting a table ID of 0 for the
default VRF, unlike iproute2 and newer FRR versions.
The first bug was discovered while fixing the second.
Both bugs are not regressions (never worked) and are not critical
in my opinion, so the fixes can be applied to net-next, if desired.
No regressions in other tests:
# ./fib_tests.sh
...
Tests passed: 191
Tests failed: 0

Cited commit added the table ID to the FIB info structure, but did not
properly initialize it when table ID 0 is used. This can lead to a route
in the default VRF with a preferred source address not being flushed
when the address is deleted.
Consider the following example:
# ip address add dev dummy1 192.0.2.1/28
# ip address add dev dummy1 192.0.2.17/28
# ip route add 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 100
# ip route add table 0 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 200
# ip route show 198.51.100.0/24
198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 100
198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200
Both routes are installed in the default VRF, but they are using two
different FIB info structures. One with a metric of 100 and table ID of
254 (main) and one with a metric of 200 and table ID of 0. Therefore,
when the preferred source address is deleted from the default VRF,
the second route is not flushed:
# ip address del dev dummy1 192.0.2.17/28
# ip route show 198.51.100.0/24
198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200
Fix by storing a table ID of 254 instead of 0 in the route configuration
structure.
Add a test case that fails before the fix:
# ./fib_tests.sh -t ipv4_del_addr

Cited commit added the table ID to the FIB info structure, but did not
prevent structures with different table IDs from being consolidated.
This can lead to routes being flushed from a VRF when an address is
deleted from a different VRF.
Fix by taking the table ID into account when looking for a matching FIB
info. This is already done for FIB info structures backed by a nexthop
object in fib_find_info_nh().

Prior to the Fixes: commit, the initialization code went through the
same fec_enet_set_coalesce() function as used by ethtool, and that
function correctly checks whether the current variant has support for
irq coalescing.
Now that the initialization code instead calls fec_enet_itr_coal_set()
directly, that call needs to be guarded by a check for the
FEC_QUIRK_HAS_COALESCE bit.

When large folios supported, one folio can be split into several slices,
each of which may be mapped to META/UNMAPPED/MAPPED, and the folio can
be unlocked as a whole only when all slices have completed.
Thus always allocate erofs_fscache_request for each .read_folio() or
.readahead(), in which case the allocated request is responsible for
unlocking folios when all slices have completed.
As described above, each folio or folio range can be mapped into several
slices, while these slices may be mapped to different cookies, and thus
each slice needs its own netfs_cache_resources. Here we introduce
chained requests to support this, where each .read_folio() or
.readahead() calling can correspond to multiple requests. Each request
has its own netfs_cache_resources and thus is used to access one cookie.
Among these requests, there's a primary request, with the others
pointing to the primary request.

The reason is erofs_fscache_register_cookie() doesn't guarantee the primary
data blob (aka fsid) is unique in the shared domain and
erofs_register_sysfs() invoked by the second mount will fail due to the
duplicated fsid in the shared domain and report warning.
It would be better to check the uniqueness of fsid before doing
erofs_register_sysfs(), so adding a new flags parameter for
erofs_fscache_register_cookie() and doing the uniqueness check if
EROFS_REG_COOKIE_NEED_NOEXIST is enabled.
After the patch, the error in dmesg for the duplicated mount would be:

pass down large folios containing multiple pages.
Let's enable this for non-compressed format for now, until the
compression part supports large folios later.
When large folios supported, the iomap routine will allocate iomap_page
for each large folio and thus we need iomap_release_folio() and

The t8103 CPU nodes are missing the cache hierarchy information. The
cache hierarchy on Arm can not be detected and needs to be described in
DT. The OS scheduler can make use of this information for scheduling
decisions.
The cache size information is based on various articles about the
processors. There's also an L3 system level cache (SLC). It's not
described here because SLCs typically have some MMIO interface which
would need to be described.
Based on Rob Herring's patch adding cache properties and nodes for
t600x.

There are fields 'last_hwmon_state' and 'last_thermal_state' in the
structure 'emc2305_cdev_data', which respectively store the cooling state
set by the 'hwmon' and 'thermal' subsystem, and the driver author hopes
that if the state set by 'hwmon' is lower than the value set by 'thermal',
the driver will just save it without actually setting the pwm. Currently,
the 'last_thermal_state' also be updated by 'hwmon', which will cause the
cooling state to never be set to a lower value. This patch fixes that.

readl() already handles endian conversion. That's the main difference
between readl() and __raw_readl(). This is benign on little-endian
systems, but big endian systems will end up byte-swabbing twice.

The first argument to the CXL AER trace points is the source device.
Pass a 'const struct device *' rather than a 'const char *' for more
type precision / safety.
