13 The ARM CPU is capable of addressing a maximum of 4GB virtual memory
30 ffff1000	ffff7fff	Reserved.
33 ffff0000	ffff0fff	CPU vector page.
34 				The CPU vectors are mapped here if the
35 				CPU supports vector relocation (control
39 				in proc-xscale.S to flush the whole data
43 				DTCM mounted inside the CPU.
46 				ITCM mounted inside the CPU.
53 ff800000	ffbfffff	Permanent, fixed read-only mapping of the
59 VMALLOC_START	VMALLOC_END-1	vmalloc() / ioremap() space.
68 PAGE_OFFSET	high_memory-1	Kernel direct-mapped RAM region.
72 PKMAP_BASE	PAGE_OFFSET-1	Permanent kernel mappings
76 MODULES_VADDR	MODULES_END-1	Kernel module space
80 TASK_SIZE	MODULES_VADDR-1	KASAn shadow memory when KASan is in use.
85 00001000	TASK_SIZE-1	User space mappings
86 				Per-thread mappings are placed here via
89 00000000	00000fff	CPU vector page / null pointer trap
97 in a non-bootable kernel, or may cause the kernel to (eventually) panic
