Subject: ACPI: APEI: Enable APEI multiple GHES source to share a single
|
|
external IRQ
|
|
|
|
X-Gene platforms describe multiple GHES error sources with the same
|
|
hardware error notification type (external interrupt) and interrupt
|
|
number.
|
|
|
|
Change the GHES interrupt request to support sharing the same IRQ.
