[PATCH v2 0/2] arm: kasan: support CONFIG_KASAN_VMALLOC

[Lecopzer Chen]

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
