[Xen-devel] [PATCH v4 06/39] arm/p2m: Cosmetic fix - substitute _gfn(ULONG_MAX) for INVALID_GFN

[Sergej Proskurin <proskurin@xxxxxxxxxxxxx>]

In ./xen/arch/arm/p2m.c, we compare the gfn's with INVALID_GFN
throughout the code. Thus it makes sense to use the macro INVALID_GFN
instead of a hard coded value to initialize "p2m->lowest_mapped_gfn".
