/*
* NOTE: Code in clear_user_page has a hard coded dependency on the

/*
- * We can't do this since copy_user_page is used to bring in
- * file data that might have instructions. Since the data would
- * then need to be flushed out so the i-fetch can see it, it
- * makes more sense to just copy through the kernel translation
- * and flush it.
+ * copy_user_page_asm() performs a page copy using mappings
+ * equivalent to the user page mappings. It can be used to
+ * implement copy_user_page() but unfortunately both the `from'
+ * and `to' pages need to be flushed through mappings equivalent
+ * to the user mappings after the copy because the kernel accesses
+ * the `from' page through the kmap kernel mapping and the `to'
+ * page needs to be flushed since code can be copied. As a
+ * result, this implementation is less efficient than the simpler
+ * copy using the kernel mapping. It only needs the `from' page
+ * to flushed via the user mapping. The kunmap routines handle
+ * the flushes needed for the kernel mapping.
*
* I'm still keeping this around because it may be possible to
* use it if more information is passed into copy_user_page().
