ARM: 9202/1: kasan: support CONFIG_KASAN_VMALLOC

mainline inclusion
from mainline-v6.0-rc1
commit 565cbaad
category: bugfix
bugzilla: 187411, https://gitee.com/openeuler/kernel/issues/I5O600?from=project-issue
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=565cbaad83d83e288927b96565211109bc984007



--------------------------------

Simply make shadow of vmalloc area mapped on demand.

Since the virtual address of vmalloc for Arm is also between
MODULE_VADDR and 0x100000000 (ZONE_HIGHMEM), which means the shadow
address has already included between KASAN_SHADOW_START and
KASAN_SHADOW_END.
Thus we need to change nothing for memory map of Arm.

This can fix ARM_MODULE_PLTS with KASan, support KASan for higmem
and support CONFIG_VMAP_STACK with KASan.
