powerpc/pseries: Don't give a warning when HPT resizing isn't available
As of 438cc81a41 "powerpc/pseries: Automatically resize HPT for memory hot add/remove" when running on the pseries platform, we always attempt to use the PAPR extension to resize the hashed page table (HPT) when we add or remove memory. This is fine, but when the extension is available we'll give a harmless, but scary warning. This patch suppresses the warning in this case. It will still warn if the feature is supposed to be available, but didn't work. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
