Julius Werner 983c09ebdb drivers: char: mem: Fix wraparound check to allow mappings up to the end ... commit 32829da54d9368103a2f03269a5120aa9ee4d5da upstream. A recent fix to /dev/mem prevents mappings from wrapping around the end of physical address space. However, the check was written in a way that also prevents a mapping reaching just up to the end of physical address space, which may be a valid use case (especially on 32-bit systems). This patch fixes it by checking the last mapped address (instead of the first address behind that) for overflow.
