Linux 7.5 Adds hwpoison-panic Tool

Linux 7.5 will include a new hwpoison-panic tool for the kernel source tree. This feature tests the vm.paniconunrecoverablememoryfailure option to force an immediate kernel panic during unrecoverable memory failures. The tool injects hardware poison errors on kernel pages and requires the --yes-panic-my-kernel argument to avoid accidental crashes, primarily for VM testing.
