The issue here is that we allocate "data" and then set "data = PTR_ALIGN(data, 8);" and then we free the aligned pointer instead of the original pointer. kmalloc() pointers are already ARCH_SLAB_MINALIGN aligned which is 8 or more on everything except certain Xtensa variants. We decided that if the Xtensa people ever notice a bug here then we'll tell them the bug is on their side. ;)
I am not sure if it was decided to be a xtensa bug, but just to ignore the issue until it would arise. Anyway, not sure if the last sentence is useful in the commit message.
