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
