Subject: [PATCH v3 0/3] x86/mm/64: Remove vmalloc/ioremap pgtable synchronization
Date: Tue, 21 Jul 2020 11:59:50 +0200	[thread overview]
Message-ID: <20200721095953.6218-1-joro@8bytes.org> (raw)

From: Joerg Roedel <jroedel@suse.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

Changes to v2:

	- Rebased to tip/master
	- Some rewording of the commit-messages
