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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
