x86/mm: Untangle __change_page_attr_set_clr(.checkalias)
The .checkalias argument to __change_page_attr_set_clr() is overloaded
and serves two different purposes:
- it inhibits the call to cpa_process_alias() -- as suggested by the
name; however,
- it also serves as 'primary' indicator for __change_page_attr()
( which in turn also serves as a recursion terminator for
cpa_process_alias() ).
Untangle these by extending the use of CPA_NO_CHECK_ALIAS to all
callsites that currently use .checkalias=0 for this purpose.
