but with the following differences:
- The Yellow and Blue LEDs are available but disabled
- The Red and Green LEDs are used to signal off/on status
- uart_AO can be accessed after opening the case; soldered pins exist
- QCA9377 instead of the usual Ampak/Broadcom module

APEI is unable to do all of its error handling work in nmi-context, so
it defers non-fatal work onto the irq_work queue. arch_irq_work_raise()
sends an IPI to the calling cpu, but this is not guaranteed to be taken
before returning to user-space.
Unless the exception interrupted a context with irqs-masked,
irq_work_run() can run immediately. Otherwise return -EINPROGRESS to
indicate ghes_notify_sea() found some work to do, but it hasn't
finished yet.
With this apei_claim_sea() returning '0' means this external-abort was
also notification of a firmware-first RAS error, and that APEI has

Fix these errors with help of the following rules:
1: Add nodename in the preferred form.
2: Always add a label that ends with '_led' to prevent conflicts
with other labels such as 'power' and 'mmc'
3: If leds need pinctrl add a label that ends with '_led_pin'
also to prevent conflicts with other labels.
patternProperties:
# The first form is preferred, but fall back to just 'led'

A new kgdb feature will soon land (kgdb_earlycon) that lets us run
kgdb much earlier. In order for everything to work properly it's
important that the break hook is setup by the time we process
"kgdbwait".
Right now the break hook is setup in debug_traps_init() and that's
called from arch_initcall(). That's a bit too late since
kgdb_earlycon really needs things to be setup by the time the system
calls dbg_late_init().
We could fix this by adding call_break_hook() into early_brk64() and
that works fine. However, it's a little ugly. Instead, let's just
add a call to debug_traps_init() straight from trap_init(). There's
already a documented dependency between trap_init() and
debug_traps_init() and this makes the dependency more obvious rather
than just relying on a comment.
NOTE: this solution isn't early enough to let us select the
"ARCH_HAS_EARLY_DEBUG" KConfig option that is introduced by the
kgdb_earlycon patch series. That would only be set if we could do
breakpoints when early params are parsed. This patch only enables
"late early" breakpoints, AKA breakpoints when dbg_late_init() is
called. It's expected that this should be fine for most people.
It should also be noted that if you crash you can still end up in kgdb
earlier than debug_traps_init(). Since you don't need breakpoints to
debug a crash that's fine.

There is nothing architecture-specific about scs_overflow_check() as
it's just a trivial wrapper around scs_corrupted().
For parity with task_stack_end_corrupted(), rename scs_corrupted() to
task_scs_end_corrupted() and call it from schedule_debug() when
CONFIG_SCHED_STACK_END_CHECK_is enabled, which better reflects its
purpose as a debug feature to catch inadvertent overflow of the SCS.
Finally, remove the unused scs_overflow_check() function entirely.
This has absolutely no impact on architectures that do not support SCS
(currently arm64 only).

Storing the SCS information in thread_info as a {base,offset} pair
introduces an additional load instruction on the ret-to-user path,
since the SCS stack pointer in x18 has to be converted back to an offset
by subtracting the base.
