Subject: [PATCH 0/3] page table check default to warn instead of panic

From: Pasha Tatashin <tatashin@...gle.com>

Page table check when detects errors panics the kernel. Let instead,
print a warning, and panic only when specifically requested via kernel
parameter:

	page_table_check=panic

The discussion about using panic vs. warn is here:
https://lore.kernel.org/linux-mm/20220902232732.12358-1-rick.p.edgecombe@intel.com

Pasha Tatashin (2):
  mm/page_table_check: Do WARN_ON instead of BUG_ON by default
  doc/vm: add information about page_table_check=panic

Rick Edgecombe (1):
  mm/page_table_check: Check writable zero page in page table check
