Just like with hugetlbpage.c, this file too has other problems 
beyond trivial style issues:

 - one_page_table_init() logic should be restructured to have its 
   branch condition inverted into a goto out pattern, to get rid of 
   the ugly linebreaks.

 - that ugly check in page_table_kmap_check() should be factored out
   into a helper inline

 - kernel_physical_mapping_init() is too large and should have its 
   innards factored out into one or more helper inlines.

 - there's too many #idefs obscuring the easy readability of the 
   code. Could some be eliminated?

Some style issues as well:

 - printk(KERN_* should be converted to pr_*(

 - the #include files section looks unstructured and ugly. Please 
   take a look at arch/x86/mm/fault.c and try to eliminate all 
   unnecessary include lines and follow the format of fault.c.

These (and other issues) should be addressed as well, so that we 
have a single act of churn there, followed by a quality end result.

Thanks,
