+RISCV64
+=======
+
+VA_BITS
+-------
+
+The maximum number of bits for virtual addresses. Used to compute the
+virtual memory ranges.
+
+PAGE_OFFSET
+-----------
+
+Indicates the virtual kernel start address of the direct-mapped RAM region.
+
+phys_ram_base
+-------------
+
+Indicates the start physical RAM address.

+MODULES_VADDR|MODULES_END|VMALLOC_START|VMALLOC_END|VMEMMAP_START|VMEMMAP_END|KERNEL_LINK_ADDR
+----------------------------------------------------------------------------------------------
+
+Used to get the correct ranges:
+
+ * MODULES_VADDR ~ MODULES_END : Kernel module space.
+ * VMALLOC_START ~ VMALLOC_END : vmalloc() / ioremap() space.
+ * VMEMMAP_START ~ VMEMMAP_END : vmemmap space, used for struct page array.
+ * KERNEL_LINK_ADDR : start address of Kernel link and BPF
