[RFC][PATCH 2/5] mm: Switch mod_state() to __this_cpu_read()

[Steven Rostedt]

From: Steven Rostedt <srostedt@xxxxxxxxxx>

The code in mod_state() is already made to handle the raciness of
this_cpu_read(). Have the code use __this_cpu_read() instead so
the debug code does not trigger warnings about it.
