From 2d3553ecb4e316a74571da253191c37fb90cb815 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sat, 15 Mar 2025 18:30:22 +0800 Subject: crypto: scomp - Remove support for some non-trivial SG lists As the only user of acomp/scomp uses a trivial single-page SG list, remove support for everything else in preprataion for the addition of virtual address support. However, keep support for non-trivial source SG lists as that user is currently jumping through hoops in order to linearise the source data. Limit the source SG linearisation buffer to a single page as that user never goes over that. The only other potential user is also unlikely to exceed that (IPComp) and it can easily do its own linearisation if necessary. Also keep the destination SG linearisation for IPComp.
