[Qemu-devel] [PATCH 2/4] linux-user: specify the cpu model during configure

[Laurent Vivier]

From: Laurent Vivier <address@hidden>

This patch allows to set the default cpu model for a given architecture,
for instance:

 ./configure --target-list=m68k-linux-user,arm-linux-user \
               --m68k-default-cpu=m68040 --arm-default-cpu=sa1100
