"powerpc fixes for 4.19 #4
Four regression fixes.
A fix for a change to lib/xz which broke our zImage loader when
building with XZ compression. OK'ed by Herbert who merged the
original patch.
The recent fix we did to avoid patching __init text broke some 32-bit
machines, fix that.
Our show_user_instructions() could be tricked into printing kernel
memory, add a check to avoid that.
And a fix for a change to our NUMA initialisation logic, which causes
crashes in some kdump configurations.
Thanks to:
Christophe Leroy, Hari Bathini, Jann Horn, Joel Stanley, Meelis
Roos, Murilo Opsfelder Araujo, Srikar Dronamraju."
