x86: c_p_a clflush_cache_range fix
Because in i386 early boot stage, boot_cpu_data may be not available, which makes clflush_cach_range() into infinite loop, which is called by change_page_attr(). This patch fixes this by setting boot_cpu_data.x86_clflush_size in early_cpu_detect(). Signed-off-by: NHuang Ying <ying.huang@intel.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
