Re: [PATCH 02/13] powerpc/64: Provide functions for accessing POWER9 partition table

+#ifdef CONFIG_PPC_BOOK3S_64
+void mmu_partition_table_init(void)
+{
+	unsigned long patb_size = 1UL << PATB_SIZE_SHIFT;
+
+	BUILD_BUG_ON_MSG((PATB_SIZE_SHIFT > 24), "Partition table size too large.");

This should be 36 (12 + 24)

+	partition_tb = __va(memblock_alloc_base(patb_size, patb_size,
+						MEMBLOCK_ALLOC_ANYWHERE));
