From 52b81ab5e95a64cb6973fc4d60d2319c4305ddf8 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 12 Jul 2017 17:53:17 +1000 Subject: pseries: Enable HPT resizing for 2.10 We've now implemented a PAPR extensions which allows PAPR guests (i.e. "pseries" machine type) to resize their hash page table during runtime. However, that extension is only enabled if explicitly chosen on the command line. This patch enables it by default for spapr-2.10, but leaves it disabled (by default) for older machine types.
