Fix device tree schema validation messages like 'gpio-line-names'

sifive,gpio.yaml'.

The bindings were missing the gpio-line-names element, which was

wireguard: selftests: set CONFIG_NONPORTABLE on riscv32
When the CONFIG_PORTABLE/CONFIG_NONPORTABLE switches were added, various
configs were updated, but the wireguard config was forgotten about. This
leads to unbootable test kernels, causing CI fails. Add
CONFIG_NONPORTABLE=y to the wireguard test suite configuration for
riscv32.

RISC-V: KVM: Support sstc extension
Sstc extension allows the guest to program the vstimecmp CSR directly
instead of making an SBI call to the hypervisor to program the next
event. The timer interrupt is also directly injected to the guest by
the hardware in this case. To maintain backward compatibility, the
hypervisors also update the vstimecmp in an SBI set_time call if
the hardware supports it. Thus, the older kernels in guest also
take advantage of the sstc extension.

1bf7d836e5 perf record: Improve error message of -p not_existing_pid
When one uses -p $not_existing_pid, the output of --help is printed:

   Usage: perf record [<options>] [<command>]
      or: perf record [<options>] -- <command> [<options>]

Let's change it something similar what perf top -p $not_existing_pid
prints:

  $ ./perf top -p 123456789 --stdio
  Error:

Newly suggested error message:

aa0c680c3a block: Do not call blk_put_queue() if gendisk allocation fails
Commit 6f8191fdf4 ("block: simplify disk shutdown") removed the call
to blk_get_queue() during gendisk allocation but missed to remove the
corresponding cleanup code blk_put_queue() for it. Thus, if the gendisk
allocation fails, the request_queue refcount gets decremented and
reaches 0, causing blk_mq_release() to be called with a hctx still
alive. That triggers a WARNING report, as found by syzkaller:

32ad11127b xen/xenbus: fix return type in xenbus_file_read()
This code tries to store -EFAULT in an unsigned int.  The
xenbus_file_read() function returns type ssize_t so the negative value
is returned as a positive value to the user.

This change forces another change to the min() macro.  Originally, the
min() macro used "unsigned" type which checkpatch complains about.  Also
unsigned type would break if "len" were not capped at MAX_RW_COUNT.  Use
size_t for the min().  (No effect on runtime for the min_t() change).

402c43ea6b xen-blkfront: Apply 'feature_persistent' parameter when connect
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 aac8a70db2 ("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 74a852479c
("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.

fc9be616bb xen-blkback: fix persistent grants negotiation
Persistent grants feature can be used only when both backend and the
frontend supports the feature.  The feature was always supported by
'blkback', but commit aac8a70db2 ("xen-blkback: add a parameter for
disabling of persistent grants") has introduced a parameter for
disabling it runtime.

To avoid the parameter be updated while being used by 'blkback', the
commit caches the parameter into 'vbd->feature_gnt_persistent' in
'xen_vbd_create()', and then check if the guest also supports the
feature and finally updates the field in 'connect_ring()'.

However, 'connect_ring()' could be called before 'xen_vbd_create()', so
later execution of 'xen_vbd_create()' can wrongly overwrite 'true' to
'vbd->feature_gnt_persistent'.  As a result, 'blkback' could try to use
'persistent grants' feature even if the guest doesn't support the
feature.

This commit fixes the issue by moving the parameter value caching to
'xen_blkif_alloc()', which allocates the 'blkif'.  Because the struct
embeds 'vbd' object, which will be used by 'connect_ring()' later, this
should be called before 'connect_ring()' and therefore this should be
the right and safe place to do the caching.

Implement support for the HVMOP_set_evtchn_upcall_vector hypercall in
order to set the per-vCPU event channel vector callback on Linux and
use it in preference of HVM_PARAM_CALLBACK_IRQ.

If the per-VCPU vector setup is successful on BSP, use this method
for the APs. If not, fallback to the global vector-type callback.

Also register callback_irq at per-vCPU event channel setup to trick
toolstack to think the domain is enlightened.

ab2579d795 LoongArch: Jump to the link address before enable PG
The kernel entry points of both boot CPU (i.e., kernel_entry) and non-
boot CPUs (i.e., smpboot_entry) may be physical address from BootLoader
(in DA mode or identity-mapping PG mode). So we should jump to the link
address before PG enabled (because DA is disabled at the same time) and
just after DMW configured.

Specifically: With some older firmwares, non-boot CPUs started with PG
enabled, but this need firmware cooperation in the form of a temporary
page table, which is deemed unnecessary. OTOH, latest firmware versions
configure the non-boot CPUs to start in DA mode, so kernel-side changes
are needed.
