arm64: tegra: Device tree changes for v5.12-rc1
Fixes an issue with HDA codec detection by properly wiring up the
power-domain for the HDA controller. This also fixes one of the USB-C
ports on Jetson AGX Xavier and enables support for audio on various
Tegra210, Tegra186 and Tegra194 boards. The Jetson Nano and Jetson TX1
also gain QSPI support.

We currently just percolate the return value from analyze_instr()
to the caller of emulate_step(), especially if it is a -1.
For one particular case (opcode = 4) for instructions that aren't
currently emulated, we are returning 'should not be single-stepped'
while we should have returned 0 which says 'did not emulate, may
have to single-step'.

Queued spinlocks have shown to have good performance and fairness
properties even on smaller (2 socket) POWER systems. This selects them
automatically for 64s. For other platforms they are de-selected, the
standard spinlock is far simpler and smaller code, and single chips
with a handful of cores is unlikely to show any improvement.
CONFIG_EXPERT still allows this to be changed, e.g., to help debug
performance or correctness issues.

The hv_24x7 performance monitoring unit creates a list of supported
events from the event catalog obtained via HCALL. The hv_24x7 catalog
could also contain invalid or dummy events with names like RESERVED*.
These events do not have any hardware counters backing them. Add a
check to string compare the event names to filter such events out.
Result on power9 machine:

In commit 8150a153c013 ("powerpc/64s: Use early_mmu_has_feature() in
set_kuap()") we switched the KUAP code to use early_mmu_has_feature(),
to avoid a bug where we called set_kuap() before feature patching had
been done, leading to recursion and crashes.
That path, which called probe_kernel_read() from printk(), has since
been removed, see commit 2ac5a3bf7042 ("vsprintf: Do not break early
boot with probing addresses").
Additionally probe_kernel_read() no longer invokes any KUAP routines,
since commit fe557319aa06 ("maccess: rename probe_kernel_{read,write}
to copy_{from,to}_kernel_nofault") and c33165253492 ("powerpc: use
non-set_fs based maccess routines").
So it should now be safe to use mmu_has_feature() in the KUAP
routines, because we shouldn't invoke them prior to feature patching.
This is essentially a revert of commit 8150a153c013 ("powerpc/64s: Use
early_mmu_has_feature() in set_kuap()"), but we've since added a
second usage of early_mmu_has_feature() in get_kuap(), so we convert
that to use mmu_has_feature() as well.

free_ldt_pgtables() uses the MMU gather API for batching TLB flushes
over the call to free_pgd_range(). However, tlb_gather_mmu() expects
to operate on user addresses and so passing LDT_{BASE,END}_ADDR will
confuse the range setting logic in __tlb_adjust_range(), causing the
gather to identify a range starting at TASK_SIZE. Such a large range
will be converted into a 'fullmm' flush by the low-level invalidation
code, so change the caller to invoke tlb_gather_mmu_fullmm() directly.

With retpolines disabled, some configurations of GCC, and specifically
the GCC versions 9 and 10 in Ubuntu will add Intel CET instrumentation
to the kernel by default. That breaks certain tracing scenarios by
adding a superfluous ENDBR64 instruction before the fentry call, for
functions which can be called indirectly.
CET instrumentation isn't currently necessary in the kernel, as CET is
only supported in user space. Disable it unconditionally and move it
into the x86's Makefile as CET/CFI... enablement should be a per-arch
decision anyway.
