Merge remote-tracking branch 'afaerber/tags/qom-cpu-for-anthony' into staging
QOM CPUState refactorings / X86CPU * Conversion of global CPU list to QTAILQ - preparing for CPU hot-unplug * Document X86CPU magic numbers for CPUID cache info # gpg: Signature made Tue 03 Sep 2013 10:59:22 AM CDT using RSA key ID 3E7E013F # gpg: Can't check signature: public key not found # By Andreas Färber (3) and Eduardo Habkost (1) # Via Andreas Färber * afaerber/tags/qom-cpu-for-anthony: target-i386: Use #defines instead of magic numbers for CPUID cache info cpu: Replace qemu_for_each_cpu() cpu: Use QTAILQ for CPU list a15mpcore: Use qemu_get_cpu() for generic timers
