Subject: [PATCH] ia64: select ACPI_NUMA if ACPI
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6c33eb39976b67628452ebc791834c7d590e545e;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[PATCH] ia64: select ACPI_NUMA if ACPI

When ACPI && NUMA, pxm_to_node is used and it exists in drivers/acpi/numa.c

Tony said:

  The patch makes sense ...  if you pick both of "ACPI" and "NUMA", then you
  need (and should automatically be given) ACPI_NUMA too.

  The only open question is whether there is a better way of getting there.
  Perhaps with less configuration options in the first place?  We are heading
  towards a future where so many systems will be NUMA that there would seem to
  be little benefit in keeping ACPI_NUMA separate from ACPI ...  but perhaps
  we aren't quite there yet.
