Subject: [PATCH 28/38] arm64/efi: Add ALLINT to IRQ flags checks
Date: Mon, 14 Sep 2026 11:20:52 +0100 [thread overview]
Message-ID: <20260914102102.68597-29-vladimir.murzin@arm.com> (raw)
In-Reply-To: <20260914102102.68597-1-vladimir.murzin@arm.com>
EFI is not expected to modify PSTATE.ALLINT, so check that it remains
unchanged across EFI runtime calls.
