Subject: [RFT 2/2] Revert "RISC-V: mark hibernation as nonportable"
Date: Wed, 2 Aug 2023 12:12:53 +0100	[thread overview]
Message-ID: <20230802-chef-throng-d9de8b672a49@wendy> (raw)
In-Reply-To: <20230802-purse-hydrant-6f44f77364b0@wendy>

Revert commit ed309ce52218 ("RISC-V: mark hibernation as nonportable")
as the kernel now has a way to handle the "no-map"-less, PMP protected,
reserved memory nodes for the affected versions of OpenSBI.
