From 15c3c114ed144e5d9ad0f9e8f9f2998bae372190 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Tue, 30 Oct 2018 15:08:58 -0700 Subject: memblock: replace alloc_bootmem_pages with memblock_alloc The alloc_bootmem_pages() function allocates PAGE_SIZE aligned memory. memblock_alloc() with alignment set to PAGE_SIZE does exactly the same thing. The conversion is done using the following semantic patch: @@ expression e; @@ - alloc_bootmem_pages(e) + memblock_alloc(e, PAGE_SIZE) Link: http://lkml.kernel.org/r/1536927045-23536-20-git-send-email-rppt@linux.vnet.ibm.com Signed-off-by: Mike Rapoport Acked-by: Michal Hocko Cc: Catalin Marinas Cc: Chris Zankel Cc: "David S.
