Hi,

as discussed here are the updates to the recent patches and fixes to
pre-allocate the vmalloc/ioremap second-level page-table pages on
x86-64.

Patch one is a re-send of

commit 8bb9bf242d1f ("x86/mm/64: Do not sync vmalloc/ioremap mappings")

with more explanations about what broke, what fixed it and why its now
safe to apply it again.

Patch two updates the comment in preallocate_vmalloc_pages(), it is
mostly the wording from Dave Hansen, so he really deserved the
authorship of it. I just didn't want to commit/send it in his name.
Feel free to change authorship of this patch to him.

Regards,

Joerg
