Subject: [PATCH 0/2] x86: high compat r/o M2P table handling adjustments
Date: Wed, 15 Apr 2020 10:21:23 +0200 [thread overview]
Message-ID: <fc61fd42-0e09-0f13-bccb-ba0202d936ca@suse.com> (raw)
In-Reply-To: <91728ed9a191160e6405267f5ae05cb6d3724f22.1586352238.git.hongyxia@amazon.com>
While looking at "x86_64/mm: map and unmap page tables in
destroy_compat_m2p_mapping" it occurred to me that the mappings
changed there can be dropped altogether, as can the linear
address range used for this. Note that both patches have only
been lightly tested so far, I guess in particular the 2nd one
may still have issues.
1: x86: drop unnecessary page table walking in compat r/o M2P handling
2: x86: drop high compat r/o M2P table address range
