Hi Matt,
On 7.3.y, commit 4bef20bbb9e0 ("alpha: handle VM_FAULT_HWPOISON in
do_page_fault()") was backported as it was marked Cc stable. 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

Queued the whole commit for 7.3, 6.18, 6.12 and 6.6, thanks. We have no alpha
compiler here, so a build check on your side would be welcome.

Thanks,
