I don't think it does? :) I think you're referring to the batch handling in arch/powerpc/include/asm/book3s/64/tlbflush-hash.h ? But that's only used for 64-bit Book3S with the HPT MMU. > By trivially enabling > the ARCH_WANT_BATCHED_UNMAP_TLB_FLUSH in ppc, ppc arch can re-use > common code in rmap and reduce overhead and do optimization it could not > have without a tlb flushing context at low architecture level. > > Signed-off-by: Luming Yu <luming...@shingroup.cn> > --- > arch/powerpc/Kconfig | 1 + > arch/powerpc/include/asm/tlbbatch.h | 30 +++++++++++++++++++++++++++++ > 2 files changed, 31 insertions(+) > create mode 100644 arch/powerpc/include/asm/tlbbatch.h This doesn't build: https://github.com/linuxppc/linux-snowpatch/actions/runs/10919442655 Can you please follow the instructions here: https://github.com/linuxppc/wiki/wiki/Testing-with-GitHub-Actions Which describe how to fork our CI tree that has Github Actions preconfigured, then you can apply your patches on top and push to github and it will do some test builds for you. Notably it will do 32-bit builds which is what broke here. cheers
