This patch enables CONFIG_NODES_SPAN_OTHER_NODES by default
for NUMA. As some NUMA nodes have memory ranges that span other
nodes. Even though a pfn is valid and between a node's start and
end pfns, it may not reside on that node.

Please do not use 'This patch' in changelogs. It's pointless because we
already know that this is a patch.

See also Documentation/process/submitting-patches.rst and search for 'This
patch'

Simply say:

  Remove CONFIG_NODES_SPAN_OTHER_NODES as it's enabled by default with
  NUMA.

But .....

the changelog does not mention that this lifts the dependency on
X86_64_ACPI_NUMA and therefore enables that functionality for anything
which has NUMA enabled including 32bit.

The core mm change gives no helpful information either. You just copied the
above comment text from some random Kconfig.

This needs a bit more data in the changelogs and the cover letter:

     - Why is it useful to enable it unconditionally

     - Why is it safe to do so, even if the architecture had constraints on
       it

     - What's the potential impact

Thanks,

the changelog does not mention that this lifts the dependency on
X86_64_ACPI_NUMA and therefore enables that functionality for anything
which has NUMA enabled including 32bit.

The core mm change gives no helpful information either. You just copied the
above comment text from some random Kconfig.

This needs a bit more data in the changelogs and the cover letter:

     - Why is it useful to enable it unconditionally

     - Why is it safe to do so, even if the architecture had constraints on
       it

     - What's the potential impact

Thanks,

Please do not use 'This patch' in changelogs. It's pointless because we
already know that this is a patch.

See also Documentation/process/submitting-patches.rst and search for 'This
patch'

Simply say:

  Remove CONFIG_NODES_SPAN_OTHER_NODES as it's enabled by default with
  NUMA.

But .....

This is not a comment on the patch series itself, it is a comment on the emails.

Your email is mis-configured and ends up all being marked as spam for
me, because you go through the wrong smtp server (or maybe your smtp
server itself is miconfigured)

All your emails fail dmarc, because the "From" header is
os.amperecomputing.com, but the DKIM signature is for
amperemail.onmicrosoft.com.

End result: it wil all go into the spam box of anybody who checks DKIM.

Please describe the problem more thoroughly. What is the layout, what
doesn't work with the default configuration and why do we need this
particular fix rather than enabling of the config option for the
specific HW.

Please describe the problem more thoroughly. What is the layout, what
doesn't work with the default configuration and why do we need this
particular fix rather than enabling of the config option for the
specific HW.

It appears Microsoft enables DKIM by default, but does so using keys
advertised at *.onmicrosoft.com domains, and our IT folks didn't
initially notice this. We believe we've rectified the situation, so
please let us know if our emails (including this one) continue to be an
issue.

Interestingly, *some* receiving mail servers (at least gmail.com) were
reporting DKIM/DMARC pass for emails sent directly from our domain
(though not those sent through a mailing list), which I believe allowed
our IT to falsely think they had everything configured correctly.

I think this config is used for a NUMA layout which NUMA nodes addresses 
are spanned to other nodes. I think 32bit NUMA also have the same issue 
with that layout. Please correct me if I'm wrong.

Yes, as it's a correct comment and is used at multiple places.

I think this config is used for a NUMA layout which NUMA nodes addresses 
are spanned to other nodes. I think 32bit NUMA also have the same issue 
with that layout. Please correct me if I'm wrong.

Yes, as it's a correct comment and is used at multiple places.

I'm not saying you're wrong, but it's your duty to provide the analysis why
this is correct for everything which has NUMA enabled.

Well it maybe correct in terms of explaining what this is about, it still
does not explain why this is needed by default on everything which has NUMA
enabled.
