Date: Thu, 1 Oct 2020 13:16:45 -0700 From: Sudarshan Rajagopalan <sudaraja@...eaurora.org> To: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Cc: Sudarshan Rajagopalan <sudaraja@...eaurora.org> Subject: [PATCH v3] arm64/mm: add fallback option to allocate virtually V1: The initial patch used the approach to abort at the first instance of PMD_SIZE allocation failure, unmaps all previously mapped sections using vmemmap_free and maps the entire request with vmemmap_populate_basepages to allocate virtually contiguous memory. https://lkml.org/lkml/2020/9/10/66 V2: Allocates virtually contiguous memory only for sections that failed PMD_SIZE allocation, and continues to allocate physically contiguous memory for other sections. https://lkml.org/lkml/2020/9/30/1489 V3: Addresses Anshuman's comment to allow fallback to altmap base pages as well if and when required.
