memblock: replace alloc_bootmem_low_pages with memblock_alloc_low
The alloc_bootmem_low_pages() function allocates PAGE_SIZE aligned regions from low memory. memblock_alloc_low() with alignment set to PAGE_SIZE does exactly the same thing. The conversion is done using the following semantic patch: @@ expression e; @@ - alloc_bootmem_low_pages(e) + memblock_alloc_low(e, PAGE_SIZE) Link: http://lkml.kernel.org/r/1536927045-23536-19-git-send-email-rppt@linux.vnet.ibm.com Signed-off-by: Mike Rapoport <rppt@linux.vnet.ibm.com> Acked-by: Michal Hocko <mhocko@suse.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Chris Zankel <chris@zankel.net> Cc: "David S.
