It looks like we accidentally dropped execute permissions from the
scripts when picking them from the list. Locally I get a slightly
different failure:

  ALL    scripts/atomic/check-atomics.sh
  scripts/atomic/check-atomics.sh: line 16: 
  scripts/atomic/gen-atomic-instrumented.sh: Permission denied
  warning: include/asm-generic/atomic-instrumented.h is out-of-date.
  scripts/atomic/check-atomics.sh: line 16: 
  scripts/atomic/gen-atomic-long.sh: Permission denied
  warning: include/asm-generic/atomic-long.h is out-of-date.
  scripts/atomic/check-atomics.sh: line 16: 
  scripts/atomic/gen-atomic-fallback.sh: Permission denied
  warning: include/linux/atomic-fallback.h is out-of-date.

I've sent a patch [1] to fix this.

Thanks,
Mark.
