I've just discovered that I've booted qemu-sparc with the wrong kernel and this patch crashes miserably :( The better version that does allow qemu-sparc to boot with folded page tables is below: From a90e1d157b7f8786a4276ffc8553f2167c8bc0e7 Mon Sep 17 00:00:00 2001 From: Mike Rapoport <rppt@xxxxxxxxxxxxx> Date: Tue, 1 Oct 2019 17:14:38 +0300 Subject: [PATCH v2] sparc32: use pgtable-nopud instead of 4level-fixup 32-bit version of sparc has three-level page tables and can use pgtable-nopud and folding of the upper layers. Replace usage of include/asm-generic/4level-fixup.h with include/asm-generic/pgtable-nopud.h and adjust page table manipulation macros and functions accordingly.
