From: Sergey Senozhatsky <sergey.senozhatsky.work@xxxxxxxxx>
a) Do not pass console_loglevel to macros, use console_loglevel directly.
b) Use CONSOLE_LOGLEVEL_MOTORMOUTH instead of a naked number
c) Use bust_spinlocks() to set/clear oops_in_progress
d) Fix checkpatch error: Macros with multiple statements should be
enclosed in a do - while loop
