When a process tries to access a page that is already offline, the kernel will send a sigbus signal with the BUS_MCEERR_AR code. This signal is typically handled by a registered sigbus handler in the process. However, if the process does not have a registered sigbus handler, it is important for end users to be informed about what happened. To address this, add an error message similar to those implemented on the x86, powerpc, and parisc platforms.
