Subject: accel/tcg: Merge tcg_exec_init into tcg_init_machine
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=fa79cde6ed245629141b5a084f3110b8a3131d60;p=qmiga%2Fqemu.git

accel/tcg: Merge tcg_exec_init into tcg_init_machine

There is only one caller, and shortly we will need access
to the MachineState, which tcg_init_machine already has.
