patch for kernel 4.10

Kernel 4.10 has 
struct taint_flag {
	char true;	/* character printed when tainted */
	char false;	/* character printed when not tainted */
	bool module;	/* also show as a per-module taint flag */
};

which won't compile if any macro defining 'true' or 'false' is in effect.

Furthermore, get_user_pages_remote has got an additional parameter int *locked.

My patch doesn't initialize this parameter which might be wrong

patch for kernel 4.10.0-rc2

[Comment 2 Helmut Jarausch 2017-01-02 11:20:36 UTC]

While 4.10.0-rc1 still contained the dummy declaration

static inline int register_cpu_notifier(struct notifier_block *nb)
{
	return 0;
}

this was removed in 4.10.0-rc2 .

I can confirm that virtualbox-modules-5.1.16 build just fine with
kernel 4.11.0-rc2 without any patching of the kernel.
