Since __bitwise types are not supported by the tracing infrastructure, store

Please give the field in the trace even the proper type instead of

Hi Christoph,
I will do that. BTW, I discovered the code in the tracing infrastructure
that makes sparse unhappy:
#define is_signed_type(type) (((type)(-1)) < (type)1)
Sparse reports four warnings for that expression if 'type' is a bitwise
type. Two of these warnings can be suppressed by changing 'type' into
'__force type'. I have not yet found a way to suppress all the sparse
warnings triggered by the is_signed_type() macro for bitwise types.
Thanks,
Bart.
