The ARM trusted foundations code is currently broken in linux-next when
CONFIG_KCOV_INSTRUMENT_ALL is set:
/tmp/ccHdQsCI.s: Assembler messages:
/tmp/ccHdQsCI.s:37: Error: .err encountered
/tmp/ccHdQsCI.s:38: Error: .err encountered
/tmp/ccHdQsCI.s:39: Error: .err encountered
scripts/Makefile.build:311: recipe for target 'arch/arm/firmware/trusted_foundations.o' failed
I could not find a function attribute that lets me disable
-fsanitize-coverage=trace-pc for just one function, so this turns it off
for the entire file instead.
