[PATCH v10 02/18] arm64: hibernate: variable pudp is used instead of pd4dp

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There should be p4dp used when p4d page is allocated.
This is not a functional issue, but for the logical correctness this
should be fixed.

Fixes: e9f6376858b9 ("arm64: add support for folded p4d page tables")
