[PATCH] kmsan: include linux/vmalloc.h

[Arnd Bergmann <arnd@xxxxxxxxxx>]

From: Arnd Bergmann <arnd@xxxxxxxx>

This is needed for the vmap/vunmap declarations:

mm/kmsan/kmsan_test.c:316:9: error: implicit declaration of function 'vmap' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
        vbuf = vmap(pages, npages, VM_MAP, PAGE_KERNEL);
               ^
mm/kmsan/kmsan_test.c:316:29: error: use of undeclared identifier 'VM_MAP'
        vbuf = vmap(pages, npages, VM_MAP, PAGE_KERNEL);
                                   ^
mm/kmsan/kmsan_test.c:322:3: error: implicit declaration of function 'vunmap' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
                vunmap(vbuf);
                ^
