In case if the platform doesn't have BIOS or a comprehensive firmware
installed then the HBA capability flags will be left uninitialized. As a
good alternative we suggest to define the DT-properties with the AHCI
platform capabilities describing all the HW-init flags of the
corresponding capability register. Luckily there aren't too many of them.
SSS - Staggered Spin-up support and MPS - Mechanical Presence Switch
support determine the corresponding feature availability for the whole HBA
by means of the "hba-cap" property. Each port can have the "hba-port-cap"
property initialized indicating that the port supports some of the next
functionalities: HPCP - HotPlug capable port, MPSP - Mechanical Presence
Switch attached to a port, CPD - Cold Plug detection, ESP - External SATA
Port (eSATA), FBSCP - FIS-based switching capable port.

The Broadcom SATA controller is obviously based on the AHCI standard. The
device driver uses the kernel AHCI library to work with it. Therefore we
can be have a more thorough DT-bindings evaluation by referring to the
AHCI-common schema instead of using the more relaxed SATA-common one.

The denoted in the description upper limit only concerns the Port
Multipliers, but not the actual SATA ports. It's an external device
attached to a SATA port in order to access more than one SATA-drive. So
when it's attached to a SATA port it just extends the port capability
while the number of actual SATA ports stays the same. For instance on AHCI
controllers the number of actual ports is determined by the CAP.NP field
and the PI (Ports Implemented) register. AFAICS in general the maximum
number of SATA ports depends on the particular controller implementation.
Generic AHCI controller can't have more than 32 ports (since CAP.NP is of
5 bits wide and PI register is 32-bits size), while DWC AHCI SATA
controller can't be configured with more than 8 ports activated. So let's
discard the SATA ports reg-property restrictions and just make sure that
it consists of a single reg-item.

Indeed in accordance with what is implemented in the AHCI platform driver
and the way the AHCI DT nodes are defined in the DT files we can add the
next AHCI DT properties constraints: AHCI CSR ID is fixed to 'ahci', PHY
name is fixed to 'sata-phy', AHCI controller can't have more than 32 ports
by design, AHCI controller can have up to 32 IRQ lines.

In order to create a more sophisticated AHCI controller DT bindings let's
divide the already available generic AHCI platform YAML schema into the
platform part and a set of the common AHCI properties. The former part
will be used to evaluate the AHCI DT nodes mainly compatible with the
generic AHCI controller while the later schema will be used for more
thorough AHCI DT nodes description. For instance such YAML schemas design
will be useful for our DW AHCI SATA controller derivative with four clock
sources, two reset lines, one system controller reference and specific
max Rx/Tx DMA xfers size constraints.
Note the phys and target-supply property requirement is preserved in the
generic AHCI platform bindings because some platforms can lack of the
explicitly specified PHYs or target device power regulators.
Also note the SATA/AHCI ports properties have been moved to the
$defs-paragraph of the schemas. It's done in order to create the
extendable properties hierarchy such that particular AHCI-controller
could add vendor-specific port properties.

Seeing doubtfully any SATA device working without embedded DMA engine
let's permit the device nodes being equipped with the dma-coherent
property in case if the platform is capable of cache-coherent DMAs.
As a side-effect we can drop the explicit dma-coherent property definition
from the particular device schemas. Currently it concerns the Broadcom
SATA AHCI controller only.

In some use cases[1], the backend is created while the frontend doesn't
support the persistent grants feature, but later the frontend can be
changed to support the feature and reconnect. In the past, 'blkback'
enabled the persistent grants feature since it unconditionally checked
if frontend supports the persistent grants feature for every connect
('connect_ring()') and decided whether it should use persistent grans or
not.
However, commit aac8a70db24b ("xen-blkback: add a parameter for
disabling of persistent grants") has mistakenly changed the behavior.
It made the frontend feature support check to not be repeated once it
shown the 'feature_persistent' as 'false', or the frontend doesn't
support persistent grants.
Similar behavioral change has made on 'blkfront' by commit 74a852479c68
("xen-blkfront: add a parameter for disabling of persistent grants").
This commit changes the behavior of the parameter to make effect for
every connect, so that the previous behavior of 'blkfront' can be
restored.

This sentence dates back to the pre-git era and it does not look very
professional... As there is no clear definition of "finished", and given
this page is already a pretty good overview, not to mention it is not the
kernel responsibility to document the protocol in detail, let's update the
text accordingly.

Fix device tree schema validation error messages for the SiFive
Unmatched: ' cache-sets:0:0: 1024 was expected'.
The existing bindings allow for just 1024 cache-sets but the fu740 on
Unmatched the has 2048 cache-sets. The ISA itself permits any arbitrary
power of two, however this is not supported by dt-schema. The RTL for
the IP, to which the number of cache-sets is a tunable parameter, has
been released publicly so speculatively adding a small number of
"reasonable" values seems unwise also.
Instead, as the binding only supports two distinct controllers: add 2048
and explicitly lock it to the fu740's l2 cache while limiting 1024 to
the l2 cache on the fu540.
Fixes: af951c3a113b ("dt-bindings: riscv: Update l2 cache DT documentation to add support for SiFive FU740")

Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth, bpf, can and netfilter.
A little larger than usual but it's all fixes, no late features. It's
large partially because of timing, and partially because of follow ups
to stuff that got merged a week or so before the merge window and
wasn't as widely tested. Maybe the Bluetooth fixes are a little
alarming so we'll address that, but the rest seems okay and not scary.
Notably we're including a fix for the netfilter Kconfig [1], your WiFi
warning [2] and a bluetooth fix which should unblock syzbot [3].
Current release - regressions:
- Bluetooth:
- don't try to cancel uninitialized works [3]
- L2CAP: fix use-after-free caused by l2cap_chan_put
- tls: rx: fix device offload after recent rework
- devlink: fix UAF on failed reload and leftover locks in mlxsw
Current release - new code bugs:
- netfilter:
- flowtable: fix incorrect Kconfig dependencies [1]
- nf_tables: fix crash when nf_trace is enabled

Previous releases - regressions:
- wifi: cfg80211: fix validating BSS pointers in
__cfg80211_connect_result [2]
- atm: bring back zatm uAPI after ATM had been removed
- properly fix old bug making bonding ARP monitor mode not being able
to work with software devices with lockless Tx
- tap: fix null-deref on skb->dev in dev_parse_header_protocol
- revert "net: usb: ax88179_178a needs FLAG_SEND_ZLP" it helps some
devices and breaks others
- netfilter:
- nf_tables: many fixes rejecting cross-object linking which may
lead to UAFs
- nf_tables: fix null deref due to zeroed list head
- nf_tables: validate variable length element extension
- bgmac: fix a BUG triggered by wrong bytes_compl
- bcmgenet: indicate MAC is in charge of PHY PM
Previous releases - always broken:

There is unexpected warning on KVM_CAP_VM_DISABLE_NX_HUGE_PAGES capability
table, which cause the table to be rendered as paragraph text instead.
The warning is due to missing colon at capability name and returns keyword,
as well as improper alignment on multi-line returns field.
Fix the warning by adding missing colons and aligning the field.

This series is based on the alternatives changes done in my svpbmt
series and thus also depends on Atish's isa-extension parsing series.
It implements using the cache-management instructions from the Zicbom-
extension to handle cache flush, etc actions on platforms needing them.
SoCs using cpu cores from T-Head like the Allwinne D1 implement a
different set of cache instructions. But while they are different,
instructions they provide the same functionality, so a variant can easly
hook into the existing alternatives mechanism on those.
[Palmer: Some minor fixups, including a RISCV_ISA_ZICBOM dependency on
MMU that's probably not strictly necessary. The Zicbom support will
trip up sparse for users that have new toolchains, I just sent a patch.]
