A previous patch tried to get Linux to use the ESRT under Xen if it is
in memory of type EfiRuntimeServicesData. However, EfiRuntimeServices*
memory needs to be included in the EFI page tables, so it is best to
minimize the amount of memory of this type. Since EFI runtime services
do not need access to the ESRT, EfiACPIReclaimMemory is a better choice.

Should this be included in 4.17? It is a bug fix for a feature new to
4.17, so I suspect yes, but it is ultimately up to Henry Wang. The code
is identical to v2, but I have improved the commit message.
It may be too late now, looking at the state of the tree. Henry, Julien?
Like I said in v2, I don't object the change if you would like to include this
patch
to 4.17, so if you are sure this patch is safe and want to commit it, feel free
to add:
Release-acked-by: Henry Wang <[email protected]>
Since we also need to commit:
"[PATCH for-4.17] SUPPORT.md: Define support lifetime" so from my side
I am no problem. Julien might have different opinion though, if Julien object
the change I would like to respect his opinion and leave this patch uncommitted.
I have committed it after SUPPORT.md. So if for some reasons we are seen
any issues with Osstest, then I can tag the tree without this patch
(that said, I would rather prefer if we have staging-4.17 == stable-4.17).
My plan is to prepare the tarball tomorrow.
Cheers,
