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)
