[v2] Add RAS support for RISC-V architecture

[RFC PATCH v2 03/10] acpi: Introduce SSE in HEST notification types

Posted by Himanshu Chauhan 5 months, 1 week ago

Introduce a new HEST notification type for RISC-V SSE events.
The GHES entry's notification structure contains the notification
to be used for a given error source. For error sources delivering
events over SSE, it should contain the new SSE notification type.
