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 <rppt@linux.vnet.ibm.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Chris Zankel <chris@zankel.net> Cc: "David S.
