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
