Subject: [PATCH v3 0/3] x86/mm/64: Remove vmalloc/ioremap pgtable synchronization

From: Joerg Roedel <jroedel@...e.de>

Hi,

here is the third version of the patches to pre-allocate P4D/PUD pages
for the vmalloc/ioremap areas on x86-64. This makes the page-table
synchronization code obsolete and so it is also removed.

Please review.

Thanks,

	Joerg
