Changelog:
v2:
 - Moved "Check writable zero page in page table check" to be last in
   series so not to add more BUG_ON.
 - Removed page_table_check=panic as was suggested by Mathew Wilcox
v1:
  https://lore.kernel.org/linux-mm/20220911095923.3614387-1-pasha.tatashin@soleen.com/

Page table check when detects errors panics the kernel, instead,
print warnings as it is more useful, and it was agreed the right
behaviour for kernel.

In case when panic is still preferred, there is panic_on_warn sysctl
option.
