From 2a5bda5a624d6471d25e953b9adba5182ab1b51f Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Tue, 30 Oct 2018 15:09:09 -0700 Subject: memblock: replace alloc_bootmem with memblock_alloc The alloc_bootmem(size) is a shortcut for allocation of SMP_CACHE_BYTES aligned memory. When the align parameter of memblock_alloc() is 0, the alignment is implicitly set to SMP_CACHE_BYTES and thus alloc_bootmem(size) and memblock_alloc(size, 0) are equivalent. The conversion is done using the following semantic patch: @@ expression size; @@ - alloc_bootmem(size) + memblock_alloc(size, 0) Link: http://lkml.kernel.org/r/1536927045-23536-22-git-send-email-rppt@linux.vnet.ibm.com Signed-off-by: Mike Rapoport Cc: Catalin Marinas Cc: Chris Zankel Cc: "David S.
