Re: [Qemu-devel] [PATCH 1/3] Make 'qemu_init_vcpu' a function (instead of a macro)

[Lluís Vilanova]

Please ignore these patches.

Implementation of 'qemu_init_vcpu' in CONFIG_USER_ONLY must be moved into a C
file to avoid an include loop between trace.h and qemu-common.h

Ideas on which file this is supposed to go?
