Tong Tiangen 018ebe4c18 arm64: fix types in copy_highpage() ... [ Upstream commit 921d161f15d6b090599f6a8c23f131969edbd1fa ] In copy_highpage() the `kto` and `kfrom` local variables are pointers to struct page, but these are used to hold arbitrary pointers to kernel memory . Each call to page_address() returns a void pointer to memory associated with the relevant page, and copy_page() expects void pointers to this memory. This inconsistency was introduced in commit 2563776b41 ("arm64: mte: Tags-aware copy_{user_,}highpage() implementations") and while this doesn't appear to be harmful in practice it is clearly wrong. Correct this by making `kto` and `kfrom` void pointers.
