For D-side errors we print data load/store address as 'Effective address'
that caused MC. In addition to print NIP, print kernel function name as well.
After this patch the MCE console log would look like:
[ 291.444281] Severe Machine check interrupt [Recovered]
[ 291.444477] NIP [d00000001bc70194]: init_module+0x194/0x2b0 [bork_kernel]
[ 291.444707] Initiator: CPU
[ 291.444761] Error type: SLB [Parity]
[ 291.444793] Effective address: d000000026de0000
