Since the framework of KASAN_VMALLOC is well-developed, It's easy to support for ARM that simply not to map shadow of VMALLOC area on kasan_init.
This can fix ARM_MODULE_PLTS with KASAN and provide first step to support CONFIG_VMAP_STACK in ARM.
Patch base on v5.16
Test on 1. Qemu with memory 2G and vmalloc=500M for 3G/1G mapping. 2. Qemu with memory 2G and vmalloc=500M for 3G/1G mapping + LPAE. 3. Qemu with memory 2G and vmalloc=500M for 2G/2G mapping.
v2: rebase on 5.17-rc3
