boards/x86: add Intel64 (64-bit long-mode) QEMU target board Add qemu_x86_long board (with CONFIG_X86_LONGMODE=y) for testing. This requires adding support to soc/ia32 for long mode (trivial), and adding a quick 64- to 32-bit ELF conversion before invoking QEMU, which apparently doesn't like 64-bit kernel files.

arch/x86: (Intel64) add z_arch_curr_cpu() to enable CONFIG_SMP=y And set qemu_x86_long board to build with CONFIG_SMP=y by default. Apparently two benchmark tests - latency_measure and sys_kernel - do not work with the SMP scheduler, so those tests are disabled. Signed-off-by: Charles E. Youse <charles.youse@intel.com>

arch/x86: (Intel64) implement SMP support Add duplicate per-CPU data structures (x86_cpuboot, tss, stacks, etc.) for up to 4 total CPUs, add code in locore and z_arch_start_cpu(). The test board, qemu_x86_long, now defaults to 2 CPUs. Signed-off-by: Charles E. Youse <charles.youse@intel.com>
