函数名称：pu init entry point, called from mce.c with preempt off

函数原型：void mce_amd_feature_init(struct cpuinfo_x86 *c)

返回类型：void

参数：

类型参数名称
struct cpuinfo_x86 *c
628  cpu等于当前cpu ID()
629  low等于0, high等于0, address等于0
630  offset等于负1
633  以bank小于Operations with implied preemption/interrupt protection. These* operations can be used without worrying about preemption or interrupt.(mce_num_banks)循环
634  如果* Indicates that overflow conditions are not fatal, when set.则smca_configure(bank, cpu)
637  Turn off thresholding banks for the following conditions:* - MC4_MISC thresholding is not supported on Family 0x15.* - Prevent possible spurious interrupts from the IF bank on Family 0x17* Models 0x10-0x2F due to Erratum #1114.
639  以block小于NR_BLOCKS循环
640  address等于get_block_address(address, low, high, bank, block, cpu)
641  如果非address则退出
644  如果dmsr with exception handling (address, & low, & high)则退出
647  如果非high按位与MASK_VALID_HI的值则继续下一循环
650  如果非high按位与MASK_CNTP_HI的值或high按位与MASK_LOCKED_HI则继续下一循环
654  offset等于prepare_threshold_block(bank, block, address, offset, high)
658  如果* Indicates that overflow conditions are not fatal, when set.则deferred_error_interrupt_enable(c)
