powerpc/mm: Fix build break when CMA=n && SPAPR_TCE_IOMMU=y
[ Upstream commit a05ef161cdd22faccffe06f21fc8f1e249565385 ]
Currently the build breaks if CMA=n and SPAPR_TCE_IOMMU=y:
arch/powerpc/mm/mmu_context_iommu.c: In function ‘mm_iommu_get’:
arch/powerpc/mm/mmu_context_iommu.c:193:42: error: ‘MIGRATE_CMA’ undeclared (first use in this function)
if (get_pageblock_migratetype(page) == MIGRATE_CMA) {
^~~~~~~~~~~
Fix it by using the existing is_migrate_cma_page(), which evaulates to
false when CMA=n.
Fixes: 2e5bbb5461f1 ("KVM: PPC: Book3S HV: Migrate pinned pages out of CMA")
