Subject: [PATCH 0/3] xen: remove some checks for always present Xen features
Date: Thu, 22 Apr 2021 17:10:04 +0200 [thread overview]
Message-ID: <20210422151007.2205-1-jgross@suse.com> (raw)
Some features of Xen can be assumed to be always present, so add a
central check to verify this being true and remove the other checks.
Juergen Gross (3):
xen: check required Xen features
xen: assume XENFEAT_mmu_pt_update_preserve_ad being set for pv guests
xen: assume XENFEAT_gnttab_map_avail_bits being set for pv guests
