Subject: translate-all: remove hole in PageDesc
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=94da9aec2a50f0c82e6c60939275c0337f03d5fe;p=qemu.git

translate-all: remove hole in PageDesc

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.
