However, it introduces `show_signal_msg()', which was introduced with commit e517a172b776 ("alpha: select SYSCTL_EXCEPTION_TRACE"). This commit was not marked Cc stable and therefore never landed on 7.3.y. This resulted in a build failure on 7.3.4: arch/alpha/mm/fault.c: In function ‘do_page_fault’: arch/alpha/mm/fault.c:242:9: error: implicit declaration of function ‘show_signal_msg’ [-Wimplicit-function-declaration] 242 | show_signal_msg(regs, address, SIGBUS, "hardware memory error"); | ^~~~~~~~~~~~~~~ Please consider (partially) backporting this patch to fix build on Alpha. Best Regards, Mingcong Bai
