The ARM 32-bit kernel fails to build with:

this is due to 341d4e6294d9 ("highmem: add memcpy_to_folio() and memcpy_from_folio()"). We would need to also back port 00cdf76012ab ("("mm: add memcpy_from_file_folio()")
And there is this other build failure caused by 997f9c35fcad ("Bluetooth: MGMT: fix crash in set_mesh_sync and set_mesh_complete")

We would need to back port 26dd68d293fd but this does not apply cleanly.
