When the I3C subsystem wants to assign a dynamic address using the SETDASA
CCC, it needs to attach the I3C device with device info that includes only
the static address. In the HCI, if the driver want to send this SETDASA
CCC, a DAT entry is required to temporarily fill the device's static
address into the dynamic address field. Afterward, the reattach API will
be executed to update the DAT with the correct dynamic addrees value.

====================
udp: Add 4-tuple hash for connected sockets
This patchset introduces 4-tuple hash for connected udp sockets, to make
connected udp lookup faster.
Stress test results (with 1 cpu fully used) are shown below, in pps:
(1) _un-connected_ socket as server
[a] w/o hash4: 1,825176
[b] w/ hash4: 1,831750 (+0.36%)
(2) 500 _connected_ sockets as server
[c] w/o hash4: 290860 (only 16% of [a])
[d] w/ hash4: 1,889658 (+3.1% compared with [b])
With hash4, compute_score is skipped when lookup, so [d] is slightly
better than [b].
Patch1: Add a new counter for hslot2 named hash4_cnt, to avoid cache line
miss when lookup.
Patch2: Add hslot/hlist_nulls for 4-tuple hash.
Patch3 and 4: Implement 4-tuple hash for ipv4 and ipv6.
The detailed motivation is described in Patch 3.
The 4-tuple hash increases the size of udp_sock and udp_hslot. Thus add it
with CONFIG_BASE_SMALL, i.e., it's a no op with CONFIG_BASE_SMALL.
Intentionally, the feature is not available for udplite. Though udplite
shares some structs and functions with udp, its connect() keeps unchanged.
So all udplite sockets perform the same as un-connected udp sockets.
Besides, udplite also shares the additional memory consumption in udp_sock
and udptable.
changelogs:
v8 -> v9 (Paolo Abeni):
- Add explanation about udplite in cover letter
- Update tags for co-developers
- Add acked-by tags of Paolo and Willem
v7 -> v8:
- add EXPORT_SYMBOL for ipv6.ko build
v6 -> v7 (Kuniyuki Iwashima):
- export udp_ehashfn to be used by udpv6 rehash
v5 -> v6 (Paolo Abeni):
- move udp_table_hash4_init from patch2 to patch1
- use hlist_nulls for lookup-rehash race
- add test results in commit log
- add more comment, e.g., for rehash4 used in hash4
- add ipv6 support (Patch4), and refactor some functions for better
sharing, without functionality change
v4 -> v5 (Paolo Abeni):
- add CONFIG_BASE_SMALL with which udp hash4 does nothing
v3 -> v4 (Willem de Bruijn):
- fix mistakes in udp_pernet_table_alloc()
RFCv2 -> v3 (Gur Stavi):
- minor fix in udp_hashslot2() and udp_table_init()
- add rcu sync in rehash4()
RFCv1 -> RFCv2:
- add a new struct for hslot2
- remove the sockopt UDP_HASH4 because it has little side effect for
unconnected sockets
- add rehash in connect()
- re-organize the patch into 3 smaller ones
- other minor fix

Implement ipv6 udp hash4 like that in ipv4. The major difference is that
the hash value should be calculated with udp6_ehashfn(). Besides,
ipv4-mapped ipv6 address is handled before hash() and rehash(). Export
udp_ehashfn because now we use it in udpv6 rehash.
Core procedures of hash/unhash/rehash are same as ipv4, and udpv4 and
udpv6 share the same udptable, so some functions in ipv4 hash4 can also
be shared.

Currently, the udp_table has two hash table, the port hash and portaddr
hash. Usually for UDP servers, all sockets have the same local port and
addr, so they are all on the same hash slot within a reuseport group.
In some applications, UDP servers use connect() to manage clients. In
particular, when firstly receiving from an unseen 4 tuple, a new socket
is created and connect()ed to the remote addr:port, and then the fd is
used exclusively by the client.
Once there are connected sks in a reuseport group, udp has to score all
sks in the same hash2 slot to find the best match. This could be
inefficient with a large number of connections, resulting in high
softirq overhead.
To solve the problem, this patch implement 4-tuple hash for connected
udp sockets. During connect(), hash4 slot is updated, as well as a
corresponding counter, hash4_cnt, in hslot2. In __udp4_lib_lookup(),
hslot4 will be searched firstly if the counter is non-zero. Otherwise,
hslot2 is used like before. Note that only connected sockets enter this
hash4 path, while un-connected ones are not affected.
hlist_nulls is used for hash4, because we probably move to another hslot
wrongly when lookup with concurrent rehash. Then we check nulls at the
list end to see if we should restart lookup. Because udp does not use
SLAB_TYPESAFE_BY_RCU, we don't need to touch sk_refcnt when lookup.
Stress test results (with 1 cpu fully used) are shown below, in pps:
(1) _un-connected_ socket as server
[a] w/o hash4: 1,825176
[b] w/ hash4: 1,831750 (+0.36%)
(2) 500 _connected_ sockets as server
[c] w/o hash4: 290860 (only 16% of [a])
[d] w/ hash4: 1,889658 (+3.1% compared with [b])
With hash4, compute_score is skipped when lookup, so [d] is slightly
better than [b].

Add a new hash list, hash4, in udp table. It will be used to implement
4-tuple hash for connected udp sockets. This patch adds the hlist to
table, and implements helpers and the initialization. 4-tuple hash is
implemented in the following patch.
hash4 uses hlist_nulls to avoid moving wrongly onto another hlist due to
concurrent rehash, because rehash() can happen with lookup().

Preparing for udp 4-tuple hash (uhash4 for short).
To implement uhash4 without cache line missing when lookup, hslot2 is
used to record the number of hashed sockets in hslot4. Thus adding a new
struct udp_hslot_main with field hash4_cnt, which is used by hash2. The
new struct is used to avoid doubling the size of udp_hslot.
Before uhash4 lookup, firstly checking hash4_cnt to see if there are
hashed sks in hslot4. Because hslot2 is always used in lookup, there is
no cache line miss.
Related helpers are updated, and use the helpers as possible.
uhash4 is implemented in following patches.

At a mapping to P2SB_DEVFN_GOLDMONT to p2sb_cpu_ids[] for Goldmont Plus,
so that the correct PCI bar gets cached.
This fixes P2SB unhiding not working on these devices, which fixes

When using FUSE DAX with virtiofs, cache coherency is managed by the
host. Disk persistence is handled via fsync() and friends, which are
passed directly via the FUSE layer to the host. Therefore, there's no
need to do dax_writeback_mapping_range(). All that ends up doing is a
cache flush operation, which is not caught by KVM and doesn't do much,
since the host and guest are already cache-coherent.
Since dax_writeback_mapping_range() checks that the inode block size is
equal to PAGE_SIZE, this fixes a spurious WARN when virtiofs is used
with a mismatched guest PAGE_SIZE and virtiofs backing FS block size
(this happens, for example, when it's a tmpfs and the host and guest
have a different PAGE_SIZE). FUSE DAX does not require any particular FS
block size, since it always performs DAX mappings in aligned 2MiB
blocks.

Function fuse_direntplus_link() might call fuse_iget() to initialize a new
fuse_inode and change its attributes. If fi->attr_version is always
initialized with 0, even if the attributes returned by the FUSE_READDIR
request is staled, as the new fi->attr_version is 0, fuse_change_attributes
will still set the staled attributes to inode. This wrong behaviour may
cause file size inconsistency even when there is no changes from
server-side.
To reproduce the issue, consider the following 2 programs (A and B) are
running concurrently,
A B
---------------------------------- --------------------------------
{ /fusemnt/dir/f is a file path in a fuse mount, the size of f is 0. }
readdir(/fusemnt/dir) start
//Daemon set size 0 to f direntry
fallocate(f, 1024)
stat(f) // B see size 1024
echo 2 > /proc/sys/vm/drop_caches
readdir(/fusemnt/dir) reply to kernel
Kernel set 0 to the I_NEW inode
stat(f) // B see size 0
In the above case, only program B is modifying the file size, however, B
observes file size changing between the 2 'readonly' stat() calls. To fix
this issue, we should make sure readdirplus still follows the rule of
attr_version staleness checking even if the fi->attr_version is lost due to
inode eviction.
To identify this situation, the new fc->evict_ctr is used to record whether
the eviction of inodes occurs during the readdirplus request processing.
If it does, the result of readdirplus may be inaccurate; otherwise, the
result of readdirplus can be trusted. Although this may still lead to
incorrect invalidation, considering the relatively low frequency of
evict occurrences, it should be acceptable.

while abeoz9_rtc_set_alarm will always set it in 24-hour mode.
We could support 12-hour mode in both functions but it seems very unlikely
that the RTC would be set to 12-hour mode now as the driver has been
setting it to 24-hour mode for a while now. The setting is undefined at
power-up and unchanged by subsequent resets which doesn't help us.

Adjust sb->s_blocksize{,_bits} directly for file-backed

Previously, EROFS used sb_set_blocksize(), which caused
a panic if bdev-backed mounts is not used.

Once a pcluster is fully decompressed and there are no attached cached
folios, its corresponding `struct z_erofs_pcluster` will be freed. This
will significantly reduce the frequency of calls to erofs_shrink_scan()
and the memory allocated for `struct z_erofs_pcluster`.
The tables below show approximately a 96% reduction in the calls to
erofs_shrink_scan() and in the memory allocated for `struct
z_erofs_pcluster` after applying this patch. The results were obtained
by performing a test to copy a 4.1GB partition on ARM64 Android devices
running the 6.6 kernel with an 8-core CPU and 12GB of memory.
1. The reduction in calls to erofs_shrink_scan():

| Average (times) | 11390 | 390 | -96.57% |

`struct erofs_workgroup` was introduced to provide a unique header
for all physically indexed objects. However, after big pclusters and
shared pclusters are implemented upstream, it seems that all EROFS
encoded data (which requires transformation) can be represented with
`struct z_erofs_pcluster` directly.
Move all members into `struct z_erofs_pcluster` for simplicity.

Support for Tegra234 was added to the tegra186 driver in 1db9b241bb (
"gpio: tegra186: Add support for Tegra234"). But the driver is not
selectable on Tegra234. Update the Kconfig entry to allow the driver to be
enabled on Tegra234.
Enable the driver by default on Tegra 234 as well, similar to the other
platforms it supports.
