How about this?

Consolidate the handling of unlikely conditions in the page_expected_state
function to reduce code duplication and improve readability.

Move the logic for handling __PG_HWPOISON flags from the check_new_page_bad
function to the page_expected_state function, and remove check_new_page_bad.

Call bad_page directly from the check_new_page function if the page has
unexpected flags.
                                                                            
Simplify the code by reducing the number of functions and centralizing the
handling of unlikely conditions.

Thanks for pointing out the formatting issue.
I would like to get your approval on the above changes before I send patch v4.
