[PATCH 0/2] ppc: rework AIL logic, add POWER10 exception model

[Nicholas Piggin]

Here are the last 2 patches of this series rebased on the ppc-for-6.1
tree.  I've tidied up the comments and control flow around the reserved
values of AIL, so different behaviours/reasons are treated individually
which hopefully addresses David's comments.

On real hardware, setting LPCR[AIL] to a reserved value (e.g., 1 on
POWER9) causes the register to retain that value but it's treated like
0, which matches what the patch does.

Thanks,
Nick
