Hello Seeteena, thanks for having this reported.
The referenced commit is upstream accepted in kernel v6.10(-rc7) and
v6.11(-rc1), hence it will be included in the planned target kernel for
'oracular' / 24.10.
And I am glad to see that the commit was upstream also tagged as stable update,
for kernel v5.9 and newer
(Fixes: 7fa95f9adaee ("powerpc/64s: system call support for scv/rfscv
instructions")
Cc: [email protected] # v5.9+)
that means it will be automatically picked by the Canonical kernel teams'
"<Ubuntu codename> update: v<version> upstream stable release" process and with
that will find it's way into noble/24.04 kernel 6.8 and jammy/22.04 kernel 5.15.
We'll use this LP bug for tracking ...

---Problem Description---
kexec fails in LPAR when some cpus are disabled
Contact Information = [email protected]
Machine Type = na
---uname output---
na
---Debugger---
A debugger is not configured
---Steps to Reproduce---
Summary:
At L1 level, kexec fails if some of the cpus in the machine are disabled.
Distros and kernel versions used:
1. Distro versions used
a. L1 LPAR :
b. L2 :
Repro steps:
1. Boot into an L1 lpar
2. Disable some cpus (eg: ppc64_cpu --cores-on=3)
3. Try to kexec.
This bug is reproducible only when we load the target kernel/initrd and use
"kexec -e" as follows:
kexec -l --initrd initramfs-$(uname -r).img vmlinuz-$(uname -r)
--append="$(cat /proc/cmdline)"
kexec -e
kexec works fine if we do a normal kexec without skipping the shutdown path
kexec --initrd initramfs-$(uname -r).img vmlinuz-$(uname -r)
--append="$(cat /proc/cmdline)"
Fix is upstream now:
