There is no point in making this feature arch-dependant now, as you use jump labels, which are arch-independent. The only reason why I had to overwrite arch_free_page in PCS6 is that I had to write some asm code to implement functionality close to that provided by jump labels, which are absent in RH6-based kernels. Please move it to mm/page_alloc.c. Thanks. _______________________________________________ Devel mailing list Devel@openvz.org https://lists.openvz.org/mailman/listinfo/devel
