From: Wen Jiang <redacted> This patchset accelerates ioremap, vmalloc, and vmap when the memory is physically fully or partially contiguous. Two techniques are used: 1. Avoid page table rewalk when setting PTEs/PMDs for multiple memory segments 2. Use batched mappings wherever possible in both vmalloc and ARM64 layers Besides accelerating the mapping path, this also enables large mappings (PMD and cont-PTE) for vmap, which are currently not supported.This series doesn't apply. I tried to apply it on top of v7.2, v7.3-rc3 and next-20260916 Can you tell how to apply it ?
Finaly I was able to apply it on top of v7.1 Christophe
