NVIDIA Turing GPUs include hardware support for USB Type-C and

required to power VR headsets through a single USB Type-C connector.

In Multi-function PCI device, one function (consumer) can have
hardware functional dependencies on another function (supplier).
Whenever the consumer is active and in D0 state, the supplier should

Flags are only read by the instructions doing the irqflags restore
operation. Pass the operand as read only to the asm inline instead of
read-write.

Version one[1] of this series attempted to fix the issue reported by
Zenghui[2] when using the function_graph tracer with IRQ priority
masking.
Since then, I realized that priority masking and the use of Pseudo-NMIs
was more broken than I thought.
* Patch 1-2 are just some cleanup
* Patch 3 fixes
Using IRQ priority masking to enable/disable interrupts is a bit
sensitive as it requires to deal with both ICC_PMR_EL1 and PSR.I.
Introduce some validity checks to both highlight the states in which
functions dealing with IRQ enabling/disabling can (not) be called, and
bark a warning when called

For el0_dbg and el0_error, DAIF bits get explicitly cleared before
calling ct_user_exit.
When context tracking is disabled, DAIF gets set (almost) immediately
after. When context tracking is enabled, among the first things done
is disabling IRQs.
What is actually needed is:
- PSR.D = 0 so the sys
Some of the inline assembly instruction use the condition flags and need
to include "cc" in the clobber list.

When using IRQ priority masking to disable interrupts, in order to deal
with the PSR.I state, local_irq_save() would convert the I bit into a
PMR value (GIC_PRIO_IRQOFF). This resulted in local_irq_restore()
potentially modifying the value of PMR in undesired location due to the
state of PSR.I upon

In the presence of any form of instrumentation, nmi_enter() should be
done before calling any traceable code and any instrumentation code.
Currently, nmi_enter() is done in handle_domain_nmi(), which is much
too late as instrumentation code might get called before. Move the
nmi_enter/exit() calls
