SYNC is defined as " #define SYNC \ sync; \ isync " in include/ppc_asm.tmpl,
and can not be used by .c file, am I right? :-). In fact it is used by the start.S file for 85xx/83xx/8xx/4xx/5xxx/74xx_7xx.
We need to define SYNC as asm("sync;").

Because SYNC is already defined in include/ppc_asm.tmpl for some ppc based CPUs to use, I use DO_SYNC instead of SYNC for this patch.
AFAICT that's a general definition which is not specific to "some ppc based CPUs" only. Rather than redefining it why not just use this definition? It seems to match our purposes.
