ARM: 9053/1: arm/mm/ptdump:Add address markers for KASAN regions
ARM has recently supported KASAN, so I think that it's time to add
KASAN regions for PTDUMP on ARM.
This patch has been tested with QEMU + vexpress-a15. Both
CONFIG_ARM_LPAE and no CONFIG_ARM_LPAE.
The result after patching looks like this:
---[ Kasan shadow start ]---
0x6ee00000-0x7af00000 193M RW NX SHD MEM/CACHED/WBWA
0x7b000000-0x7f000000 64M ro NX SHD MEM/CACHED/WBWA
---[ Kasan shadow end ]---
---[ Modules ]---
---[ Kernel Mapping ]---
......
---[ vmalloc() Area ]---
......
---[ vmalloc() End ]---
---[ Fixmap Area ]---
---[ Vectors ]---
......
---[ Vectors End ]---
