Subject: [PATCH V3 4/5] arm64/mm: Enable HugeTLB migration
Date: Tue, 23 Oct 2018 18:32:00 +0530	[thread overview]
Message-ID: <1540299721-26484-5-git-send-email-anshuman.khandual@arm.com> (raw)
In-Reply-To: <1540299721-26484-1-git-send-email-anshuman.khandual@arm.com>

Let arm64 subscribe to generic HugeTLB page migration framework. Right now
this only works on the following PMD and PUD level HugeTLB page sizes with
various kernel base page size combinations.

       CONT PTE    PMD    CONT PMD    PUD
       --------    ---    --------    ---
4K:         NA     2M         NA      1G
16K:        NA    32M         NA
64K:        NA   512M         NA
