Eli Schwartz 638edf1d42 Linux 5.8 compat: __vmalloc()
The `pgprot` argument has been removed from `__vmalloc` in Linux 5.8,
being `PAGE_KERNEL` always now [1].

Detect this during configure and define a wrapper for older kernels.

Closes #10422

(cherry picked from commit 080102a1b6)
- apply to 0.8.4 before certain files were moved around
- config/kernel-kmem.m4 exists in git but not release tarballs because
  it is unused; introduce it in a new file to prevent conflicts
- linux/mm.h is included in git master via sys/kmem.h; do not remove it
  here or the build will error due to undefined is_vmalloc_addr()
