Bah, didn't spot the dereference so this won't work either. You basically
just need to copy what I did for arm64 in d475fac95779.
Yes, this seems to work. It doesn't really need "struct mmu_gather;" -
I assume that is included from elsewhere - but I added it to be safe.
Can you send a full patch, or do you want me to do it ?
Thanks,
Guenter
