Set ARCH_SUPPORTS_SPECULATIVE_PAGE_FAULT for arm64. This
enables Speculative Page Fault handler.

This is missing your S-o-B.
You're right, I missed that...
The first patch noted that the ARCH_SUPPORTS_* option was there because
the arch code had to make an explicit call to try to handle the fault
speculatively, but that isn't addeed until patch 30.
Why is this separate from that code?
Andrew was recommended this a long time ago for bisection purpose. This
allows to build the code with CONFIG_SPECULATIVE_PAGE_FAULT before the code
that trigger the spf handler is added to the per architecture's code.
Ok. I think it would be worth noting that in the commit message, to
avoid anyone else asking the same question. :)
Should have read this thread before looking at x86 and ppc :)
In any case the patch is:

Thanks Mark and Jérôme for reviewing this.
Regarding the change in the commit message, I'm wondering if this would
be better to place it in the Series's letter head.
But I'm fine to put it in each architecture's commit.
