cache invalidation in modload
Hi,
Why is cache invalidation, i.e. kobj_machdep(), required after loading
a module? The module loading code doesn't appear to do anything
magically mystically mythical which would require a flush. The only
reason I could even begin to imagine was to flush the instruction cache.
But at least on x86 this is not required according to my interpretation
of the Intel manuals.
Also, kobj_machdep() is unimplemented on some architectures. Is it
unimplemented because it is not required or because nobody got around
to it?
