From: Andrey Konovalov <redacted>

Add wrappers around functions that [un]poison memory for vmalloc
allocations. These functions will be used by HW_TAGS KASAN and
therefore need to be disabled when kasan=off command line argument
is provided.

This patch does no functional changes for software KASAN modes.
