Hi all,
After merging the tip tree, today's linux-next build (powerpc
pseries_le_defconfig) failed to boot like this:
Built 1 zonelists, mobility grouping on. Total pages: 32736
Policy zone: Normal
mem auto-init: stack:all(zero), heap alloc:off, heap free:off
Memory: 2027392K/2097152K available (17984K kernel code, 3328K rwdata, 14784K rodata, 6080K init, 1671K bss, 69760K reserved, 0K cma-reserved)
*crickets*
Bisected to commit
f4ab23558310 ("slub: Replace cmpxchg_double()")
I have reverted that commit (and the following one) for today.

Cheers,
Stephen Rothwell

Sorry about that; turns out I forgot to test the case where cmpxchg128
wasn't available.
Please see:
https://lkml.kernel.org/r/20230524093246.GP83892@hirez.programming.kicks-ass.net
As stated there, I'm going to zap tip/locking/core for a few days and
let this fixed version run through the robots again before re-instating
it.

Note to -next, this should now be resolved in the tip:auto-latest branch.
Thanks,
