The patch uncovered an issue with top down memory mapping on x86 and this version has a preparation patch that addresses this issue. Guenter, I didn't add your Tested-by because the patch that addresses the crashes differs from the one you've tested. v4: * Add patch that prevents the crashes reported by Guenter Roeck on x86/i386 on QEMU with 256M or 512M of memory and EFI boot enabled. * Add Acked-by and Reviewed-by, thanks everybidy! v3: https://lore.kernel.org/lkml/20210803064218.6611-1-rppt@kernel.org * simplify check for exact crash kerenl allocation on arm, per Rob * make crash_max unsigned long long on arm64, per Rob v2: https://lore.kernel.org/lkml/20210802063737.22733-1-rppt@kernel.org * don't change error message in arm::reserve_crashkernel(), per Russell v1: https://lore.kernel.org/lkml/20210730104039.7047-1-rppt@kernel.org Mike Rapoport (2): x86/mm: memory_map_top_down: remove spurious reservation of upper 2M memblock: make memblock_find_in_range method private arch/arm/kernel/setup.c | 20 +++++--------- arch/arm64/kvm/hyp/reserved_mem.c | 9 +++---- arch/arm64/mm/init.c | 36 ++++++++----------------- arch/mips/kernel/setup.c | 14 +++++----- arch/riscv/mm/init.c | 44 ++++++++++--------------------- arch/s390/kernel/setup.c | 10 ++++--- arch/x86/kernel/aperture_64.c | 5 ++-- arch/x86/mm/init.c | 27 +++++++------------ arch/x86/mm/numa.c | 5 ++-- arch/x86/mm/numa_emulation.c | 5 ++-- arch/x86/realmode/init.c | 2 +- drivers/acpi/tables.c | 5 ++-- drivers/base/arch_numa.c | 5 +--- drivers/of/of_reserved_mem.c | 12 ++++++--- include/linux/memblock.h | 2 -- mm/memblock.c | 2 +- 16 files changed, 76 insertions(+), 127 deletions(-) base-commit: ff1176468d368232b684f75e82563369208bc371
