Hello, The attempt to fix destroy_xen_mappings() so that L2 tables are consistently freed uncovered some errors in the memory management code. The following series attempts to fix them.
All patches except for 4/4 are new in v2, and 4/4 has no change from v1, hence kept Jan's Reviewed-by tag in 4/4. Thanks, Roger. Roger Pau Monne (4): x86/mm: introduce helpers to detect super page alignment x86/mm: special case super page alignment detection for INVALID_MFN x86/setup: remove bootstrap_map_addr() usage of destroy_xen_mappings() x86/mm: ensure L2 is always freed if empty xen/arch/x86/include/asm/page.h | 7 +++++++ xen/arch/x86/mm.c | 13 ++++--------- xen/arch/x86/setup.c | 4 +++- 3 files changed, 14 insertions(+), 10 deletions(-) -- 2.46.0
