[patch 66/96] memblock: replace alloc_bootmem_pages_nopanic with memblock_alloc_nopanic

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Mike Rapoport <rppt@xxxxxxxxxxxxxxxxxx>
Subject: 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()
