Just as a clarification: I was referring to the zeroing of "mem" in
swiotlb_late_init_with_tbl and swiotlb_init_with_tbl. While it looks
like Tom and Christoph are talking about the zeroing of "tlb".
The zeroing of "mem" is required as some fields of struct io_tlb_mem
need to be initialized to zero. While the zeroing of "tlb" is not
required except from the point of view of not leaking sensitive data as
Christoph mentioned.
Either way, Claire's v14 patch 01/12 looks fine to me.
