Or at least put a reference in proc.rst to this doc file and its

thanks.
I *can* put it there but I did have reason not to, i.e. these attributes
are neither there:
DirectMap4k: 3930904 kB
DirectMap2M: 29440000 kB
DirectMap1G: 1048576 kB
And they are implemented in arch specific code.
Actually they are undocumented, e.g.
$ git grep DirectMap4k
arch/powerpc/mm/book3s64/pgtable.c: seq_printf(m, "DirectMap4k: %8lu kB\n",
arch/s390/mm/pageattr.c: seq_printf(m, "DirectMap4k: %8lu kB\n",
arch/x86/mm/pat/set_memory.c: seq_printf(m, "DirectMap4k: %8lu kB\n",
Yeah, we need to add some arch-specific sections to the documentation.
That *could* just be a reference over to a new file:
Documentation/x86/meminfo.rst
along with whatever other arches provide their own fields too.
Yes, either way works. Thanks.
