Yeah, agreed, in fact we moved x86/mm back to bd1de2a7aace almost
immediately and put the L1D bits into WIP.x86/mm. Fortunately they are
on top of the rest, as you noted, so it didn't have to be rebased.

Yeah, sure - here's the updated pull request for the rest:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-mm-2020-06-04

# HEAD: bd1de2a7aace4d1d312fb1be264b8fafdb706208 x86/tlb/uv: Add a forward declaration for struct flush_tlb_info

Misc changes:

- Unexport various PAT primitives

- Unexport per-CPU tlbstate

Thanks,

Ingo
