As suggested by Andrea, pass r/w error code to gup(), upgrading read fault to writable if host pte allows it.
Looks good.
static pfn_t hva_to_pfn(struct kvm *kvm, unsigned long addr, bool atomic, - bool *async) + bool *async, bool write_fault, bool *writable)
These sort of changes make reading the callers impossible, lots of true/false and NULL parameters which we have no idea what they mean.
We should (later) change the functions to accept a structure with named fields for these parameters instead.
