For memory (pfn_valid == 1) it would be more memory efficient to use a few bits in struct page->flags In general because there are lots of uses of "range lists" it would be better to put it as a library into lib. Coding style needs some work. Too many printks. I am not sure yet the cmaps don't need reference counting. For some cases (user space support) they probably will. Need user space support, e.g. using the existing ioctls for /proc/bus/pci/* (they are currently not implemented on i386/x86-64 but should with this) Then someone would need to change the X server to use this. Needs testing on a lot of systems. Need to figure out if CMAP_ALLOW_OVERLAPPING should be set or not. Probably need to go over the combining rule etc. with a fine comb -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
