suse 2.6.5-7.75 kernel compilation issues?

Hi, I have been playing with the latest kernel and there seem to be some compilation issues with it. firstly the prototype for follow_hugetlb_page() is wrong (line 17 include/linux/hugetlb.h), it seems to be a simple matter of adding an int at the end of the argument list. this then uncovers an issue with the usage of follow_hugetlb_page at line 753 of mm/memory.c, I just added a 0 for the final write argument to make it compile. I'd be interested in knowing whether that's right thing to do, and/or some explanation of this function ;-) I can generate a patch if it's useful, but this seems kinda trivial... thanks, peter
