In an effort to move ARM64 away from the legacy MSI setup, convert the
XGENE PCIe driver to the MSI-parent infrastructure and let each device have
its own MSI domain.

Bad MSI implementations multiplex MSIs onto a single downstream interrupt,
meaning they have no concept of individual affinity.
The old MSI code did a reasonable job at this by honouring the
MSI_FLAG_NO_AFFINITY, but the new shiny device MSI code doesn't.
Teach it about the sad reality of existing hardware.

Move irq-msi-lib.h into include/linux/irqchip, making it available
to compilation units outside of drivers/irqchip.
This requires some churn in drivers to fetch it from the new location,
generated using this script:
git grep -l -w \"irq-msi-lib.h\" | \
xargs sed -i -e 's:"irq-msi-lib.h":\<linux/irqchip/irq-msi-lib.h\>:'

irq_domain_add_linear() is going away as being obsolete now. Switch to
the preferred irq_domain_create_linear(). That differs in the first
parameter: It takes more generic struct fwnode_handle instead of struct
device_node. Therefore, of_fwnode_handle() is added around the
parameter.
Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).

Use skb_pull() and skb_pull_data() to safely parse QCA dump packets.
This avoids direct pointer math on skb->data, which could lead to
invalid access if the packet is shorter than expected.

Commit:
f40139fde527 ("ublk: fix race between io_uring_cmd_complete_in_task and
ublk_cancel_cmd")
adds a request state check in ublk_cancel_cmd(), and if the request is
started, skips canceling this uring_cmd.
However, the current uring_cmd may be in ACTIVE state, without block
request coming to the uring command. Meantime, if the cached request in
tag_set.tags[tag] has been delivered to ublk server and reycycled, then
this uring_cmd can't be canceled.
ublk requests are aborted in ublk char device release handler, which
depends on canceling all ACTIVE uring_cmd. So it causes a dead loop.
Fix this issue by not taking a stale request into account when canceling
uring_cmd in ublk_cancel_cmd().

The main CPUID header <asm/cpuid.h> was originally a storefront for the
headers:
<asm/cpuid/api.h>
<asm/cpuid/leaf_0x2_api.h>
Now that the latter CPUID(0x2) header has been merged into the former,
there is no practical difference between <asm/cpuid.h> and
<asm/cpuid/api.h>.
Migrate all users to the <asm/cpuid/api.h> header, in preparation of
the removal of <asm/cpuid.h>.
Don't remove <asm/cpuid.h> just yet, in case some new code in -next
started using it.

This driver is susceptible to a form of the bug explained in commit
c26a2c2ddc01 ("gianfar: Fix TX timestamping with a stacked DSA driver")
and in Documentation/networking/timestamping.rst section "Other caveats
for MAC drivers", specifically it timestamps any skb which has
SKBTX_HW_TSTAMP, and does not consider if timestamping has been enabled
in adapter->hwtstamp_config.tx_type.
Evaluate the proper TX timestamping condition only once on the TX
path (in tsnep_xmit_frame_ring()) and store the result in an additional
TX entry flag. Evaluate the new TX entry flag in the TX confirmation path
(in tsnep_tx_poll()).
This way SKBTX_IN_PROGRESS is set by the driver as required, but never
evaluated. SKBTX_IN_PROGRESS shall not be evaluated as it can be set
by a stacked DSA driver and evaluating it would lead to unwanted
timestamps.

On multi-node GICv4.1 system, VSGI senders always use one certain 4_1 ITS,
because find_4_1_its() returns the first its_node in the list, regardless of
which node the VSGI sender is on. This brings guest VSGI performance drop
when VM is not running on the same node as this returned ITS.
On a 2-socket environment, each with one ITS and 32 cpu, GICv4.1 enabled,
4U8G guest, 4 vcpu is running on same socket.
When the VM is on socket0, kvm-unit-tests ipi_hw result is 850ns.
When the VM is on socket1, it is 750ns.
The reason is that the VSGI sender always uses the last reported ITS (that
on socket1) to inject VSGI. The access from a CPU to a other-socket ITS
will cost 100ns more compared to an access to the local ITS.
Using the local ITS results in a 12% reduction in IPI latency.
Modify find_4_1_its() to return the first per-CPU local_4_1_its, which is
initialized when the VPE table is inherited from the ITS or from another
CPU. If it fails to find a local 4_1 ITS, it returns any 4_1 ITS like
before.
