Inhibit NMI watchdog when Alt-SysRq-T operation is underway
On large memory configuration with not so fast CPUs the NMI watchdog is
triggered when memory addresses are being gathered and printed. The code
paths for Alt-SysRq-t are sprinkled with touch_nmi_watchdog in various
places but not in this routine (or in the loop that utilizes this
function). The patch has been tested for regression on large CPU+memory
configuration (128 logical CPUs + 224 GB) and 1,2,4,16-CPU sockets with
various memory sizes (1,2,4,6,20).
