[RFC PATCH 23/32] ACPICA: Add new MADT GICC flags fields [code first?]

From: James Morse
Date: Fri Feb 03 2023 - 09:08:43 EST


Add the new flag field to the MADT's GICC structure.

'Online Capable' indicates a disabled CPU can be enabled later.

This patch probably needs to go via the upstream acpica project,
but is included here so the feature can be tested.
