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 <himangi774@xxxxxxxxx> Acked-by: Julia Lawall <julia.lawall@xxxxxxx> --- To send to: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>,linux-m68k@xxxxxxxxxxxxxxxxxxxx,linux-kernel@xxxxxxxxxxxxxxx arch/m68k/mm/init.c | 1 - 1 file changed, 1 deletion(-) diff --git a/arch/m68k/mm/init.c b/arch/m68k/mm/init.c index acaff6a..b09a3cb 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). -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-m68k" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
