Subject: sh: remove unnecessary memset after alloc_bootmem_low_pages
X-Git-Tag: firefly_0821_release~17207^2~80

sh: remove unnecessary memset after alloc_bootmem_low_pages

Because alloc_bootmem functions return the allocated memory always
zeroed, an additional call of memset on allocated memory is
unnecessary.
