[Qemu-devel] [PATCH v2 07/17] translate-all: remove hole in PageDesc


From: Emilio G. Cota
Subject: [Qemu-devel] [PATCH v2 07/17] translate-all: remove hole in PageDesc
Date: Thu, 5 Apr 2018 22:12:58 -0400

Groundwork for supporting parallel TCG generation.

Move the hole to the end of the struct, so that a u32
field can be added there without bloating the struct.
