parisc: Eliminate memset after alloc_bootmem_pages
alloc_bootmem and related function always return 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@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Helge Deller <deller@gmx.de>
