Any suggestion what the correct flag setting would be here for a 4K mapping?
I tried fixing this by changing this to pud and setting the PMD_TYPE_TABLE flag for kasan_zero_pmd. However the MMU doesn't like it and I get a first level address translation fault.
If you have any updated patches to share I'd be glad to try them out.
