[Xen-devel] [PATCH] x86/mm: pod: Use the correct memory flags for alloc_domheap_page{, s}

[Julien Grall <julien.grall@xxxxxxxxxx>]

The last parameter of alloc_domheap_page{s,} contain the memory flags and
not the order of the allocation.

Use 0 as it was before 1069d63c5ef2510d08b83b2171af660e5bb18c63
"x86/mm/p2m: use defines for page sizes".

Note that PAGE_ORDER_4K is also equal to 0 so the behavior stays the
same.
