Hi Nicholas,
First bad commit (maybe != root cause):
tree:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git
linux-4.4.y
head: 3cb069b52684a615947ba8af15e7c0866b9bb061
commit: 7b9f9ce1a7a0cb5e0e7077c960d08e6039388a9d [9473/9999] powerpc/64s: Add support for
a store forwarding barrier at kernel entry/exit
config: powerpc-allyesconfig (attached as .config)
I think this is wrong config for
testing 4.4.y
The space reserved for exception vectors is limited, and some of the
options apparently add code there which does not fit then.
We don't want to bend the code out of shape more than necessary to
support unrealisitic configurations.
Is there any practical configuration in which this is still a problem?
Thanks
Michal
