    perf_counter tools: Define and use our own u64, s64 etc. definitions · 9cffa8d5
    Paul Mackerras 提交于
    On 64-bit powerpc, __u64 is defined to be unsigned long rather than
    unsigned long long.  This causes compiler warnings every time we
    print a __u64 value with %Lx.
    
    Rather than changing __u64, we define our own u64 to be unsigned long
    long on all architectures, and similarly s64 as signed long long.
    For consistency we also define u32, s32, u16, s16, u8 and s8.  These
    definitions are put in a new header, types.h, because these definitions
    are needed in util/string.h and util/symbol.h.
    
    The main change here is the mechanical change of __[us]{64,32,16,8}
    to remove the "__".  The other changes are:
    
    * Create types.h
    * Include types.h in perf.h, util/string.h and util/symbol.h
    * Add types.h to the LIB_H definition in Makefile
    * Added (u64) casts in process_overflow_event() and print_sym_table()
      to kill two remaining warnings.
