# HEAD: 6848ac7ca39a226ede5df7af0efcc4ef0611e99c x86/mm/dump_pagetables: Use
DEFINE_SHOW_ATTRIBUTE()
The main changes in this cycle were:
- Update and clean up x86 fault handling, by Andy Lutomirski.
- Drop usage of __flush_tlb_all() in kernel_physical_mapping_init() and
related fallout, by Dan Williams.
- CPA cleanups and reorganization by Peter Zijlstra: simplify the flow
and remove a few warts.
- Other misc cleanups.
