Hi Qian, Sorry I haven't replied sooner, I've been travelling.

Thanks for debugging this, but I'd like to fix it differently. kvm_tmp has caused trouble before, with kmemleak, and it can also cause trouble with STRICT_KERNEL_RWX, so I'd like to change how it's done, rather than doing more hacks for it. It should just be a page in text that we use if needed, and don't free, which should avoid all these problems. I'll try and get that done and posted soon. cheers
