函数名称：__log_error

函数原型：static void __log_error(unsigned int bank, u64 status, u64 addr, u64 misc)

返回类型：void

参数：

类型参数名称
unsigned intbank
u64status
u64addr
u64misc
877  Do initial initialization of a struct mce
879  Bank's MCi_STATUS MSR 等于status
880  Bank's MCi_MISC MSR 等于misc
881  Machine check bank reporting the error 等于bank
882  CPU time stamp counter 等于dtsc() - returns the current TSC without ordering constraints* rdtsc() returns the result of RDTSC as a 64-bit integer
884  如果Bank's MCi_STATUS MSR 按位与addr reg. valid 则
885  Bank's MCi_ADDR MSR 等于addr
891  如果* Indicates that overflow conditions are not fatal, when set.则
892  lsb等于Bank's MCi_ADDR MSR 右移56位按位与0x3f
894  Bank's MCi_ADDR MSR 与等于GENMASK_ULL(55, lsb)
898  如果* Indicates that overflow conditions are not fatal, when set.则
899  rdmsrl(MSR_AMD64_SMCA_MCx_IPID(bank), MCA_IPID MSR: only valid on SMCA systems )
901  如果Bank's MCi_STATUS MSR 按位与synd reg. valid 则rdmsrl(MSR_AMD64_SMCA_MCx_SYND(bank), MCA_SYND MSR: only valid on SMCA systems )
905  mce_log( & m)
