The quilt patch titled
Subject: scripts/gdb: de-reference per-CPU MCE interrupts
has been removed from the -mm tree. Its filename was
scripts-gdb-de-reference-per-cpu-mce-interrupts.patch
This patch was dropped because it was merged into the mm-hotfixes-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: scripts/gdb: de-reference per-CPU MCE interrupts
Date: Mon, 23 Jun 2025 20:00:19 -0700
The per-CPU MCE interrupts are looked up by reference and need to be
de-referenced before printing, otherwise we print the addresses of the
variables instead of their contents:
MCE: 18379471554386948492 Machine check exceptions
MCP: 18379471554386948488 Machine check polls
The corrected output looks like this instead now:
MCE: 0 Machine check exceptions
MCP: 1 Machine check polls
