memblock: replace alloc_bootmem_pages_nopanic with memblock_alloc_nopanic
The alloc_bootmem_pages_nopanic(size) is a shortcut for __alloc_bootmem_nopanic(size, PAGE_SIZE, BOOTMEM_LOW_LIMIT) which allocates PAGE_SIZE aligned memory. Since BOOTMEM_LOW_LIMIT is hardwired to 0 there is no restrictions on where the allocated memory should reside. The memblock_alloc_nopanic(size, PAGE_SIZE) also allocates PAGE_SIZE aligned memory without any restrictions and thus can be used as a replacement for alloc_bootmem_pages_nopanic() Link: http://lkml.kernel.org/r/1536927045-23536-12-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.
