Build errors on kernel 6.1 and higher

[philippfriese]

During build on a Kernel 6.4.2, the following error message appears:

$ make
[...]
  CC [M]  /home/pfriese/build/xpmem/kernel/xpmem_attach.o
/home/pfriese/build/xpmem/kernel/xpmem_attach.c: In function ‘xpmem_attach’:

The first issue originates from commit 763ecb0 on 2022-09-27, titled "mm: remove the vma linked list".

The second issue originates from commit bc292ab on 2023-02-10, titled "mm: introduce vma->vm_flags wrapper functions".
