So this struct will be:

struct thread_shstk {
	u64 shstk_base;
	u64 shstk_size;
	u64 locked:1;
	u64 ibt:1;
No point in bit fields?
quoted
};

Ok?
Pretty much.

You can even remove the "shstk_" from the members and when you call the
pointer "shstk", accessing the members will read

	shstk->base
	shstk->size
	...

and all is organic and readable :)
And entirely not greppable.
