When the SBI STA extension exists we can use it to implement
paravirt steal-time support. Fill in the empty pv-time functions
with an SBI STA implementation and add the Kconfig knobs allowing
it to be enabled.

Add the files and functions needed to support paravirt time on
RISC-V. Also include the common code needed for the first
application of pv-time, which is steal-time. In the next
patches we'll complete the functions to fully enable steal-time

Userspace requires 'vlenb' to be able to encode it in reg ID. Otherwise

SBI extension registers may not be present and indeed when
running on a platform without sscofpmf the PMU SBI extension
is not. Move the SBI extension registers from the base set of
registers to the filter list. Individual configs should test
for any that may or may not be present separately. Since
the PMU extension may disappear and the DBCN extension is only
present in later kernels, separate them from the rest into
their own configs. The rest are lumped together into the same
config.

Always use register subtypes in the get-reg-list test when registers
have them. The only registers neglecting to do so were ISA extension
registers. While we don't really need to use KVM_REG_RISCV_ISA_SINGLE
(since it's zero), the main purpose is to avoid confusion and to
self-document the tests. Also add print support for the multi
registers like SBI extensions have, even though they're only used for
debugging.

While adding RISCV_SBI_EXT_REG(), acknowledge that some registers
have subtypes and extend __kvm_reg_id() to take a subtype field.
Then, update all macros to set the new field appropriately. The
general CSR macro gets renamed to include "GENERAL", but the other
macros, like the new RISCV_SBI_EXT_REG, just use the SINGLE subtype.

When an SBI extension cannot be enabled, that's a distinct state vs.
enabled and disabled. Modify enum kvm_riscv_sbi_ext_status to
accommodate it, which allows KVM userspace to tell the difference
in state too, as the SBI extension register will disappear when it
cannot be enabled, i.e. accesses to it return ENOENT. get-reg-list is
updated as well to only add SBI extension registers to the list which
may be enabled. Returning ENOENT for SBI extension registers which
cannot be enabled makes them consistent with ISA extension registers.
Any SBI extensions which were enabled by default are still enabled by
default, if they can be enabled at all.

Various ISA extension reg_list have common pattern so let us generate
these using macros.
We define two macros for the above purpose:
1) KVM_ISA_EXT_SIMPLE_CONFIG - Macro to generate reg_list for
ISA extension without any additional ONE_REG registers
2) KVM_ISA_EXT_SUBLIST_CONFIG - Macro to generate reg_list for
ISA extension with additional ONE_REG registers
This patch also adds the missing config for svnapot.

For the sake of coherency, use local labels in assembly when
applicable. This also avoid kprobes being confused when applying a
kprobe since the size of function is computed by checking where the
next visible symbol is located. This might end up in computing some
function size to be way shorter than expected and thus failing to apply
kprobes to the specified offset.

This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3.
While it is physically a key it behaves more like a switch, sending a key
down on first press and a key up on 2nd press. Therefor the switch event
is used here. Besides this behaviour it uses the HID usage-id 0xc6
(Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but
since neither 0xc6 nor 0xc8 are currently implemented at all in
soc_button_array this not to standard behaviour is not put behind a quirk
for the moment.

lockdep commit I initialized the data too late. The
same is true for the cancellation data, it must be
initialized before the cmpxchg(), otherwise it may
be done twice and possibly even overwriting data in
there already when there's a race. Fix that, which
also requires destroying the mutex in case we lost

Pull pin control fixes from Linus Walleij:
"Some driver fixes for v6.7, all are in drivers, the most interesting
one is probably the AMD laptop suspend bug which really needs fixing.
Freedestop org has the bug description:
https://gitlab.freedesktop.org/drm/amd/-/issues/2812
Summary:
- Ignore disabled device tree nodes in the Starfive 7100 and 7100
drivers.
- Mask non-wake source pins with interrupt enabled at suspend in the
AMD driver, this blocks unnecessary wakeups from misc interrupts.
This can be power consuming because in many cases the system
doesn't really suspend, it just wakes right back up.
- Fix a typo breaking compilation of the cy8c95x0 driver, and fix up
bugs in the get/set config callbacks.
- Use a dedicated lock class for the PIO4 drivers IRQ. This fixes a
crash on suspend"

When an afs_volume struct is put, its refcount is reduced to 0 before
the cell->volume_lock is taken and the volume removed from the
cell->volumes tree.
Unfortunately, this means that the lookup code can race and see a volume
with a zero ref in the tree, resulting in a use-after-free:
refcount_t: addition on 0; use-after-free.
WARNING: CPU: 3 PID: 130782 at lib/refcount.c:25 refcount_warn_saturate+0x7a/0xda

Fix this by:
(1) When putting, use a flag to indicate if the volume has been removed
from the tree and skip the rb_erase if it has.
(2) When looking up, use a conditional ref increment and if it fails
because the refcount is 0, replace the node in the tree and set the
removal flag.

The IDA usually detects double-frees, but that detection failed to
consider the case when there are no nearby IDs allocated and so we have a
NULL bitmap rather than simply having a clear bit. Add some tests to the
test-suite to be sure we don't inadvertently reintroduce this problem.
Unfortunately they're quite noisy so include a message to disregard
the warnings.

In afs_update_cell(), ret is the result of the DNS lookup and the errors
are to be handled by a switch - however, the value gets clobbered in
between by setting it to -ENOMEM in case afs_alloc_vlserver_list()
fails.
Fix this by moving the setting of -ENOMEM into the error handling for
OOM failure. Further, only do it if we don't have an alternative error
to return.
Found by Linux Verification Center (linuxtesting.org) with SVACE. Based
on a patch from Anastasia Belova [1].

Pull AFS fixes from David Howells:
"Improve the interaction of arbitrary lookups in the AFS dynamic root
that hit DNS lookup failures [1] where kafs behaves differently from
openafs and causes some applications to fail that aren't expecting
that. Further, negative DNS results aren't getting removed and are
causing failures to persist.
- Always delete unused (particularly negative) dentries as soon as
possible so that they don't prevent future lookups from retrying.
- Fix the handling of new-style negative DNS lookups in ->lookup() to
make them return ENOENT so that userspace doesn't get confused when
stat succeeds but the following open on the looked up file then
fails.
- Fix key handling so that DNS lookup results are reclaimed almost as
soon as they expire rather than sitting round either forever or for
an additional 5 mins beyond a set expiry time returning
EKEYEXPIRED. They persist for 1s as /bin/ls will do a second stat
call if the first fails"

The synth_event_gen_test module can be built in, if someone wants to run
the tests at boot up and not have to load them.
The synth_event_gen_test_init() function creates and enables the synthetic
events and runs its tests.
The synth_event_gen_test_exit() disables the events it created and
destroys the events.
If the module is builtin, the events are never disabled. The issue is, the
events should be disable after the tests are run. This could be an issue
if the rest of the boot up tests are enabled, as they expect the events to
be in a known state before testing. That known state happens to be
disabled.
When CONFIG_SYNTH_EVENT_GEN_TEST=y and CONFIG_EVENT_TRACE_STARTUP_TEST=y
a warning will trigger:
Running tests on trace events:
Testing event create_synth_test:
Enabled event during self test!

This is because the synth_event_gen_test_init() left the synthetic events
