[PATCH 00/12] ras: share firmware-first estatus handling

[Ahmed Tiba]

Platforms that rely on firmware-first RAS today only get the full Linux
handling pipeline when the records arrive through ACPI/APEI GHES. This
series lifts the generic parts of GHES into a reusable estatus core, wires
GHES up to that core, and adds a DeviceTree-facing provider so non-ACPI
systems can route CPER records through the same logic. The final patches
document the binding and the admin-guide flow.

The end result is a single estatus implementation that covers vendor record
notifier support, memory error queueing, IRQ/NMI handling and the CXL/PCIe.
GHES and DT users now simply provide transport-specific ops.

This is based on v6.19-rc1
