HI Manfred,

You changed some __get_free_page(GFP_KERNEL) to kmalloc(PAGE_SIZE,

This is a very interesting part of your patch. So, you counted the
tsc ticks and found kmalloc(PAGE_SIZE) to be *awlays* faster than
__get_free_page(GFP_KERNEL)? Are you sure?

Even if so, switching to kmalloc makes it possible to fail more often (or
sooner) than plain gfp - have you considered this?
