From f0b99a643e9613beb28af43333bbfa90d4bf85cc Mon Sep 17 00:00:00 2001 From: Himangi Saraogi Date: Sat, 19 Jul 2014 17:05:13 +0530 Subject: m68k/mm: Eliminate memset after alloc_bootmem_pages alloc_bootmem and related functions always return a zeroed region of memory. Thus a memset after calls to these functions is unnecessary. The following Coccinelle semantic patch was used for making the change: @@ expression E,E1; @@ E = \(alloc_bootmem\|alloc_bootmem_low\|alloc_bootmem_pages\|alloc_bootmem_low_pages\)(...) ... when != E - memset(E,0,E1); Signed-off-by: Himangi Saraogi Acked-by: Julia Lawall Signed-off-by: Geert Uytterhoeven --- arch/m68k/mm/init.c | 1 - 1 file changed, 1 deletion(-) (limited to 'arch') diff --git a/arch/m68k/mm/init.c b/arch/m68k/mm/init.c index acaff6a49e35..b09a3cb29b68 100644 --- a/arch/m68k/mm/init.c +++ b/arch/m68k/mm/init.c @@ -94,7 +94,6 @@ void __init paging_init(void) high_memory = (void *) end_mem; empty_zero_page = alloc_bootmem_pages(PAGE_SIZE); - memset(empty_zero_page, 0, PAGE_SIZE); /* * Set up SFC/DFC registers (user data space). -- cgit v1.2.3
