Hi, Here is the version 3 of NOKPORBE_SYMBOL series. Currently the blacklist is maintained by hand in kprobes.c which is separated from the function definition and is hard to catch up the kernel update. To solve this issue, I've introduced NOKPROBE_SYMBOL() macro for making kprobe blacklist at build time. Since the NOKPROBE_SYMBOL() macros can be placed right after the function is defined

Couple more bikesheddy things: Is there ever a reason to use a non __builtin_const_p(perms)? Maybe that should be a BUILD_BUG_ON too BUILD_BUG_ON(!builtin_const_p_perms) My brain of little size gets confused by the BUILD_BUG_ON_ZERO(foo) + vs BUILD_BUG_ON(foo); as it just seems like more text for the same content. Is there any value on the "_ZERO(foo) +" I don't understand?

Hi. Thank you for comments on asm code paravirtualization. Its direction is getting clear. Although it hasn't been finished yet, I'd like to start discussion on ia64 intrinsics paravirtualization. This patch set is just for discussion so that it is a subset of xen Linux/ia64 domU paravirtualization, not self complete. You can get the full patched tree by typing git clone
