Subject[PATCH v2] powerpc/mm: ptdump: Add missing include <asm/hvcall.h>
while PPC_PSERIES is not set, gcc build fails:

arch/powerpc/mm/ptdump/hashpagetable.c: In function ‘pseries_find’:
arch/powerpc/mm/ptdump/hashpagetable.c:262:18: error: ‘H_SUCCESS’ undeclared (first use in this function); did you mean ‘FL_ACCESS’?
if (lpar_rc != H_SUCCESS)

If PPC_PSERIES is not set, <asm/plpar_wrappers.h> does not
include <asm/hvcall.h>, which leads to this failure.

Add missing include file <asm/hvcall.h> in hashpagetable.c to fix this.
