Hi Stephen,
Can you please add the topic/kdump-hotplug branch of the powerpc tree to
linux-next. It contains a series that touches generic kexec code as well
as x86 and powerpc code.
The hope is to have to get it merged for v6.10, so it should go along
with the powerpc next branch in the merge

In a future commit the proc_handlers will change to
"const struct ctl_table".
As a preparation for that adapt the logic to work with a temporary
variable, similar to how it is done in other parts of the kernel.
Fixes: 964c9dff0091 ("stackleak: Allow runtime disabling of kernel stack
erasing")
In a future commit the sysctl core will only use
"const struct ctl_table". As a preparation for that adapt the cgroup-bpf
code.

Adapt the proc_hander function signature to make it clear that handlers
are not supposed to modify their ctl_table argument.
This is a prerequisite to moving the static ctl_table structs into
.rodata.
By migrating all handlers at once a lengthy transition can be avoided.
The patch was mostly
