[Qemu-devel] [PATCH 1/2] tcg: Introduce tcg_arch_init() function

[Eduardo Habkost <ehabkost@redhat.com>]

Many architectures have arch-specific initialization functions that are
called from CPU initialization at target-*/cpu.c.

Instead of requiring the CPU code to keep track of TCG initialization,
let an arch-specific init function to be defined, and it will get called
by tcg_exec_init().
