[PATCH] poison: add & use more constants
Add more poison values to include/linux/poison.h. It's not clear to me
whether some others should be added or not, so I haven't added any of
these:
./include/linux/libata.h:#define ATA_TAG_POISON 0xfafbfcfdU
./arch/ppc/8260_io/fcc_enet.c:1918: memset((char *)(&(immap->im_dprambase[(mem_addr+64)])), 0x88, 32);
./drivers/usb/mon/mon_text.c:429: memset(mem, 0xe5, sizeof(struct mon_event_text));
./drivers/char/ftape/lowlevel/ftape-ctl.c:738: memset(ft_buffer[i]->address, 0xAA, FT_BUFF_SIZE);
./drivers/block/sx8.c:/* 0xf is just arbitrary, non-zero noise; this is sorta like poisoning */
