Subject: [PATCH v5 08/16] xen: add wc_sec_hi to struct shared_info
Date: Mon, 11 Jan 2021 19:57:17 +0000 [thread overview]
Message-ID: <20210111195725.4601-9-dwmw2@infradead.org> (raw)
In-Reply-To: <20210111195725.4601-1-dwmw2@infradead.org>
From: David Woodhouse <dwmw@amazon.co.uk>
Xen added this in 2015 (Xen 4.6). On x86_64 and Arm it fills what was
previously a 32-bit hole in the generic shared_info structure; on
i386 it had to go at the end of struct arch_shared_info.
