函数名称：get_block_address

函数原型：static unsigned int get_block_address(unsigned int current_addr, unsigned int low, unsigned int high, unsigned int bank, unsigned int block, unsigned int cpu)

返回类型：unsigned int

参数：

类型参数名称
unsigned intcurrent_addr
unsigned intlow
unsigned inthigh
unsigned intbank
unsigned intblock
unsigned intcpu
494  addr等于0, offset等于0
496  如果bank大于等于per_cpu(mce_num_banks, cpu)或block大于等于NR_BLOCKS则返回:addr
499  如果* Indicates that overflow conditions are not fatal, when set.则返回:smca_get_block_address(bank, block, cpu)
504  当:block恒等于0
505  addr等于misc(bank)
506  退出
507  当:block恒等于1
508  offset等于low按位与MASK_BLKPTR_LO的值右移21位
509  如果offset则addr等于MCG_XBLK_ADDR加offset
511  退出
512  默认
513  addr等于current_addr先自加
515  返回:addr
