With today's kernel, I can no longer kexec any kernel on PS3:
| /proc/device-tree/chosen/linux,kernel-end: No such file or directory
| Could not get memory layout
Today's bad version: 15f7176eb1cccec0a332541285ee752b935c1c85
Yesterday's good version: 0d34fb8e93ceba7b6dad0062dbb4a0813bacd75b
Before I start bisecting (tomorrow or the day thereafter), anyone with an idea?
Thanks!

Hmm, not really.
Looking at the code the only obvious way you could end up without that
property is if you didn't have a /chosen?

We got one, but linux,kernel-end isn't there anymore. Was before.

Subject: powerpc: Correct dependency of KEXEC
commit 28794d34ecb6815a3fa0a4256027c9b081a17c5f ("powerpc/kconfig: Kill
PPC_MULTIPLATFORM") broke KEXEC, by making it dependant on BOOK3S, while it
should be PPC_BOOK3S.

kexec is a system call that implements the ability to shutdown your
current kernel, and to start another kernel. It is like a reboot
