Rewrite the whole family of x86_this_cpu_test_bit() functions as macros, so standard __my_cpu_var() and raw_cpu_read() macros can be used on percpu variables. This approach considerably simplifies implementation of functions and also introduces standard checks on accessed percpu variables. No functional changes intended.
