memblock: replace memblock_alloc_base(ANYWHERE) with memblock_phys_alloc
The calls to memblock_alloc_base(size, align, MEMBLOCK_ALLOC_ANYWHERE) and memblock_phys_alloc(size, align) are equivalent as both try to allocate 'size' bytes with 'align' alignment anywhere in the memory and panic if hte allocation fails. The conversion is done using the following semantic patch: @@ expression size, align; @@ - memblock_alloc_base(size, align, MEMBLOCK_ALLOC_ANYWHERE) + memblock_phys_alloc(size, align) Link: http://lkml.kernel.org/r/1548057848-15136-4-git-send-email-rppt@linux.ibm.com Signed-off-by: Mike Rapoport <rppt@linux.ibm.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Christophe Leroy <christophe.leroy@c-s.fr> Cc: Christoph Hellwig <hch@lst.de> Cc: "David S.
