idr_init() uses base 0 which is an invalid identifier. The new function
idr_init_base allows IDR to set the ID lookup from base 1. This avoids
all lookups that otherwise starts from 0 since 0 is always unused.

When inet_rtm_getroute() was converted to use the RCU variants of
ip_route_input() and ip_route_output_key(), the TOS parameters
stopped being masked with IPTOS_RT_MASK before doing the route lookup.
As a result, "ip route get" can return a different route than what
would be used when sending real packets.
For example:
$ ip route add 192.0.2.11/32 dev eth0
$ ip route add unreachable 192.0.2.11/32 tos 2
$ ip route get 192.0.2.11 tos 2
RTNETLINK answers: No route to host
But, packets with TOS 2 (ECT(0) if interpreted as an ECN bit) would
actually be routed using the first route:
$ ping -c 1 -Q 2 192.0.2.11
PING 192.0.2.11 (192.0.2.11) 56(84) bytes of data.
64 bytes from 192.0.2.11: icmp_seq=1 ttl=64 time=0.173 ms
--- 192.0.2.11 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.173/0.173/0.173/0.000 ms
This patch re-applies IPTOS_RT_MASK in inet_rtm_getroute(), to
return results consistent with real route lookups.

net: ipa: start adding IPA v4.5 support
This series starts updating the IPA code to support IPA hardware
version 4.5.
The first patch fixes a problem found while preparing these updates.
Testing shows the code works with or without the change, and with
the fix the code matches "downstream" Qualcomm code.
The second patch updates the definitions for IPA register offsets
and field masks to reflect the changes that come with IPA v4.5. A
few register updates have been deferred until later, because making
use of them involves some nontrivial code updates.
One type of change that IPA v4.5 brings is expanding the range of
certain configuration values. High-order bits are added in a few
cases, and the third patch implements the code changes necessary to
use those newly available bits.
The fourth patch implements several fairly minor changes to the code
required for IPA v4.5 support.
The last two patches implement changes to the GSI registers used for
IPA. Almost none of the registers change, but the range of memory
in which most of the GSI registers is located is shifted by a fixed
amount. The fifth patch updates the GSI register definitions, and
the last patch implements the memory shift for IPA v4.5.

The offsets for almost all GSI registers we use have different
offsets starting at IPA version 4.5. Only two registers remain
in their original location.
In a way though, the new register locations are not *that*
different. The entire group of affected registers has simply
been shifted down in memory by a fixed amount (0xd000). So for
example, the channel context 0 register that has a base offset of
0x0001c000 for "older" hardware now has a base offset of 0x0000f000.
This patch aims to add support for IPA v4.5 registers at their new
offets in a way that minimizes the amount of code that needs to
change. It is not ideal, but it avoids the need to maintain
a nearly complete set of additional register offset definitions.
The approach takes advantage of the fact that when accessing GSI
registers we do not access any of memory at lower end of the "gsi"
memory range (with two exceptions already noted). In particular,
we do not access anything within the bottom 0xd000 bytes of the
GSI memory range.
For IPA version 4.5, after we map the GSI memory, we adjust the
virtual memory pointer downward by the fixed amount (0xd000).
That way, register accesses using the offsets defined by the
existing GSI_REG_*() macros will resolve to the proper locations
for IPA version 4.5.
The two registers *not* affected by this offset are accessed only
in gsi_irq_setup(). There, for IPA version 4.5, we undo the general
register adjustment by adding the fixed amount back to the virtual
address to access these registers.

Update the IPA code to make use of the updated IPA v4.5 register
definitions. Generally what this patch does is, if IPA v4.5
hardware is in use:
- Ensure new registers or fields in IPA v4.5 are updated where
required
- Ensure registers or fields not supported in IPA v4.5 are not
examined when read, or are set to 0 when written
It does this while preserving the existing functionality for IPA
versions lower than v4.5.
The values to program for QSB_MAX_READS and QSB_MAX_WRITES and the
source and destination resource counts are updated to be correct for
all versions through v4.5 as well.
Note that IPA_RESOURCE_GROUP_SRC_MAX and IPA_RESOURCE_GROUP_DST_MAX
already reflect that 5 is an acceptable number of resources (which
IPA v4.5 implements).

IPA v4.5 adds a few fields to the endpoint header and extended
header configuration registers that represent new high-order bits
for certain offsets and sizes. Add code to incorporate these upper
bits into the registers for IPA v4.5.
This includes creating ipa_header_size_encoded(), which handles
encoding the metadata offset field for use in the ENDP_INIT_HDR
register in a way appropriate for the hardware version. This and
ipa_metadata_offset_encoded() ensure the mask argument passed to
u32_encode_bits() is constant.

Update "ipa_reg.h" so that register definitions support IPA hardware
version 4.5, in addition to versions 3.5.1 through v4.2. Most of
the register definitions are the same, but in some cases fields are
added, changed, or eliminated.
Updates for a few IPA v4.5 registers are more complex, and adding
those definition will be deferred to separate patches. This patch
only updates the register offset and field definitions, and adds
informational comments.
The only code change avoids accessing the backward compatibility
register for IPA version 4.5 in ipa_hardware_config(). Other IPA
v4.5-specific code changes will come later.

Netfilter changes PACKET_OTHERHOST to PACKET_HOST before invoking the
hooks as, while it's an expected value for a bridge, routing expects
PACKET_HOST. The change is undone later on after hook traversal. This
can be seen with pairs of functions updating skb>pkt_type and then
reverting it to its original value:
For hook NF_INET_PRE_ROUTING:
setup_pre_routing / br_nf_pre_routing_finish
For hook NF_INET_FORWARD:
br_nf_forward_ip / br_nf_forward_finish
But the third case where netfilter does this, for hook
NF_INET_POST_ROUTING, the packet type is changed in br_nf_post_routing
but never reverted. A comment says:
/* We assume any code from br_dev_queue_push_xmit onwards doesn't care
* about the value of skb->pkt_type. */
But when having a tunnel (say vxlan) attached to a bridge we have the
following call trace:
br_nf_pre_routing
br_nf_pre_routing_ipv6
br_nf_pre_routing_finish
br_nf_forward_ip
br_nf_forward_finish
br_nf_post_routing <- pkt_type is updated to PACKET_HOST
br_nf_dev_queue_xmit <- but not reverted to its original value
vxlan_xmit
vxlan_xmit_one
skb_tunnel_check_pmtu <- a check on pkt_type is performed
In this specific case, this creates issues such as when an ICMPv6 PTB
should be sent back. When CONFIG_BRIDGE_NETFILTER is enabled, the PTB
isn't sent (as skb_tunnel_check_pmtu checks if pkt_type is PACKET_HOST
and returns early).
If the comment is right and no one cares about the value of
skb->pkt_type after br_dev_queue_push_xmit (which isn't true), resetting
it to its original value should be safe.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Ancient gcc get this wrong:
/git/linux/tools/lib/bpf/libbpf.h:203: error: wrong number of arguments specified for 'deprecated' attribute
But when using NO_LIBBPF we should not hit this, changes for that to happen will land in 5.11 as they require
more surgery than advisable for this late in 5.10 rc.

This change converts the probe of this driver to use device-managed
register functions, and a devm_add_action_or_reset() for the regulator
disable.
With this, the exit & error paths can be removed.
Another side-effect is that this should avoid some static-analyzer's check
with respect to a potential null dereference of the regulator. The null
dereference isn't likely to happen (under normal operation), so there isn't
a requirement to have this fixed/backported in other releases.
As a note: this is removing spi_set_drvdata() since there is no other
spi_get_drvdata() (or dev_get_drvdata()) call that need it.

In the error path of rpcif_manual_xfer() the value of ret is overwritten
by value returned by reset_control_reset() function and thus returning
incorrect value to the caller.
This patch makes sure the correct value is returned to the caller of
rpcif_manual_xfer() by dropping the overwrite of ret in error path.
Also now we ignore the value returned by reset_control_reset() in the
error path and instead print a error message when it fails.

The check for the FW_FEATURE_PS3_LV1 firmware feature is already performed
in ps3_system_bus_init() before registering the driver. So if the probe
function is actually used, this feature is already known to be available.
The check for the match id is also superfluous; the condition is always
true because the bus' match function (ps3_system_bus_match()) only
considers this driver for devices having:
dev->match_id == snd_ps3_bus_driver_info.match_id.

ASUS Zephyrus G14 has two speaker pins, and the auto-parser tries to
assign an individual DAC to each pin as much as possible.
Unfortunately the third DAC has no volume control unlike the two DACs,
and this resulted in the inconsistent speaker volumes.
As a workaround, wire both speaker pins to the same DAC by modifying
the existing quirk (ALC289_FIXUP_ASUS_GA401) applied to this device.
Since this quirk entry is chained by another, we need to avoid
applying the DAC assignment change for it. Luckily, there is another
quirk entry (ALC289_FIXUP_ASUS_GA502) doing the very same thing, so we
can chain to the GA502 quirk instead.
Note that this patch uses a new flag of the generic parser,
obey_preferred_dacs, for enforcing the DACs.

The generic parser accepts the preferred_dacs[] pairs as a hint for
assigning a DAC to each pin, but this hint doesn't work always
effectively. Currently it's merely a secondary choice after the trial
with the path index failed. This made sometimes it difficult to
assign DACs without mimicking the connection list and/or the badness
table.
This patch adds a new flag, obey_preferred_dacs, that changes the
behavior of the parser. As its name stands, the parser obeys the
given preferred_dacs[] pairs by skipping the path index matching and
giving a high penalty if no DAC is assigned by the pairs. This mode
will help for assigning the fixed DACs forcibly from the codec
driver.

This patch fixes the hierarchical structure of MHI devices. Indeed,
MHI client devices are directly 'enumerated' from the mhi controller
and therefore must be direct descendants/children of their mhi
controller device, in accordance with the Linux Device Model.
Today both MHI clients and controller devices are at the same level,
this patch ensures that MHI controller is parent of its client devices.
The hierarchy is especially important for power management (safe
suspend/resume order). It is also useful for userspace to determine
relationship between MHI client devices and controllers.

Today the MHI controller name is simply cloned from the underlying
bus device (its parent), that gives the following device structure
for e.g. a MHI/PCI controller:
devices/pci0000:00/0000:00:01.2/0000:02:00.0/0000:02:00.0
devices/pci0000:00/0000:00:01.2/0000:02:00.0/0000:02:00.0/0000:02:00.0_IPCR
...
That's quite misleading/confusing and can cause device registering
issues because of duplicate dev name (e.g. if a PCI device register
two different MHI instances).
This patch changes MHI core to create indexed mhi controller names
(mhi0, mhi1...) in the same way as other busses (i2c0, usb0...).
The previous example becomes:
devices/pci0000:00/0000:00:01.2/0000:02:00.0/mhi0
devices/pci0000:00/0000:00:01.2/0000:02:00.0/mhi0/mhi0_IPCR
...
v2: move index field at the end of mhi_controller struct (before bool)
to avoid breaking well packed alignment.
