Subject: [7.3.y] Please backport e517a172b776 ("alpha: select SYSCTL_EXCEPTION_TRACE")
Date: Sat, 14 Nov 2026 18:04:08 +0800 [thread overview]
Message-ID: <4ab8d1e3-4e8d-4172-b36e-570eb1ef9e11@aosc.io> (raw)
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
