The USB 3.1 specification replaces the USB 3.0 specification and all new
devices that are running at SuperSpeed or higher speeds must report a
bcdUSB of 0x0310.
Refer to USB 3.1 Specification, Revision 1.0, Section 9.6.

The SuperspeedPlus Device Capability Descriptor has a variable size
depending on the number of sublink speed attributes.
This patch adds a macro to calculate that size. The macro takes one
argument, the Sublink Speed Attribute Count (SSAC) as reported by the
descriptor in bmAttributes[4:0].
See USB 3.1 9.6.2.5, Table 9-19.

kvm_mmu_pages_init is doing some really yucky stuff. It is setting
up a sentinel for mmu_page_clear_parents; however, because of a) the
way levels are numbered starting from 1 and b) the way mmu_page_path
sizes its arrays with PT64_ROOT_LEVEL-1 elements, the access can be
out of bounds. This is harmless because the code overwrites up to the
first two elements of parents->idx and these are initialized, and
because the sentinel is not needed in this case---mmu_page_clear_parents
exits anyway when it gets to the end of the array. However ubsan
complains, and everyone else should too.
This fix does three things. First it makes the mmu_page_path arrays
PT64_ROOT_LEVEL elements in size, so that we can write to them without
checking the level in advance. Second it disintegrates kvm_mmu_pages_init
between mmu_unsync_walk (to reset the struct kvm_mmu_pages) and
for_each_sp (to place the NULL sentinel at the end of the current path).
This is okay because the mmu_page_path is only used in
mmu_pages_clear_parents; mmu_pages_clear_parents itself is called within
a for_each_sp iterator, and hence always after a call to mmu_pages_next.
Third it changes mmu_pages_clear_parents to just use the sentinel to
stop iteration, without checking the bounds on level.

For the kvm_is_error_hva, ubsan complains if the uninitialized writable
is passed to __direct_map, even though the value itself is not used
(__direct_map goes to mmu_set_spte->set_spte->set_mmio_spte but never
looks at that argument).
Ensuring that __gfn_to_pfn_memslot initializes *writable is cheap and
avoids this kind of issue.

- kvm_create_pit had to lock only because it exposed kvm->arch.vpit very
early, but initialization doesn't use kvm->arch.vpit since the last
patch, so we can drop locking.
- kvm_free_pit is only run after there are no users of KVM and therefore
is the sole actor.
- Locking in kvm_vm_ioctl_reinject doesn't do anything, because reinject
is only protected at that place.
- kvm_pit_reset isn't used anywhere and its locking can be dropped if we
hide it.
Removing useless locking allows to see what actually is being protected
by PIT state lock (values accessible from the guest).

The lock was an overkill, the same can be done with atomics.
A mb() was added in kvm_pit_ack_irq, to pair with implicit barrier
between pit_timer_fn and pit_do_work. The mb() prevents a race that
could happen if pending == 0 and irq_ack == 0:
kvm_pit_ack_irq: | pit_timer_fn:
p = atomic_read(&ps->pending); |
| atomic_inc(&ps->pending);
| queue_work(pit_do_work);
| pit_do_work:
| atomic_xchg(&ps->irq_ack, 0);
| return;
atomic_set(&ps->irq_ack, 1); |
if (p == 0) return; |
where the interrupt would not be delivered in this tick of pit_timer_fn.
PIT would have eventually delivered the interrupt, but we sacrifice
perofmance to make sure that interrupts are not needlessly delayed.
sfence isn't enough: atomic_dec_if_positive does atomic_read first and
x86 can reorder loads before stores. lfence isn't enough: store can
pass lfence, turning it into a nop. A compiler barrier would be more
than enough as CPU needs to stall for unbelievably long to use fences.
This patch doesn't do anything in kvm_pit_reset_reinject, because any
order of resets can race, but the result differs by at most one
interrupt, which is ok, because it's the same result as if the reset
happened at a slightly different time. (Original code didn't protect
the reset path with a proper lock, so users have to be robust.)

Discard policy uses ack_notifiers to prevent injection of PIT interrupts
before EOI from the last one.
This patch changes the policy to always try to deliver the interrupt,
which makes a difference when its vector is in ISR.
Old implementation would drop the interrupt, but proposed one injects to
IRR, like real hardware would.
The old policy breaks legacy NMI watchdogs, where PIT is used through
virtual wire (LVT0): PIT never sends an interrupt before receiving EOI,
thus a guest deadlock with disabled interrupts will stop NMIs.
Note that NMI doesn't do EOI, so PIT also had to send a normal interrupt
through IOAPIC. (KVM's PIT is deeply rotten and luckily not used much
in modern systems.)
Even though there is a chance of regressions, I think we can fix the
LVT0 NMI bug without introducing a new tick policy.

After registering eld notifier, gfx driver can use this

connection event. However this action may happen when

This is not always safe, however. For example, using

The mediatek XHCI glue driver uses SET_SYSTEM_SLEEP_PM_OPS() to
conditionally set the correct suspend/resume options, and
also puts both the dev_pm_ops and the functions inside of
an #ifdef testing for CONFIG_PM_SLEEP, but those functions
then call other code that becomes unused:
drivers/usb/host/xhci-mtk.c:135:12: error: 'xhci_mtk_host_disable' defined but not used [-Werror=unused-function]
drivers/usb/host/xhci-mtk.c:313:13: error: 'usb_wakeup_enable' defined but not used [-Werror=unused-function]
drivers/usb/host/xhci-mtk.c:321:13: error: 'usb_wakeup_disable' defined but not used [-Werror=unused-function]
This replaces the #ifdef with __maybe_unused annotations so the
compiler knows it can silently drop them instead of warning.
For the DEV_PM_OPS definition, we can use an IS_ENABLED() check
to avoid defining the structure when CONFIG_PM is not set without
the #ifdef.

Commit b36f09c3c441 ("dmaengine: Add transfer termination
synchronization support") marked dmaengine_terminate_all() as
deprecated and is being replaced by explicit synchronous and asynchronous
terminate functions.
Here DMA termination are done in two cases: FIFO overrun and module
removal.
FIFO overrun is handled in interrupt context and converting
dmaengine_terminate_all() to dmaengine_terminate_async() does the same than
before.
Using synchronous termination in module removal however adds a bit more
robustness as it waits all completion callbacks have finished. Although it
looks all known DMA engines used with spi-pxa2xx don't implement
device_synchronize() callback so this too appears to be a no-op in
practice.
