Per Muli's comment on the initial series of patches. Clean-up to remove 80 char/line wrapping and make code more uniform. This patch has been tested individually and cumulatively on x86_64 and cross-compile tested on IA64. Since I have no IA64 hardware, any testing on that platform would be appreciated Thanks, Jon Signed-off-by: Jon Mason <jdmason@xxxxxxxxxx> diff -r 1d9d729a821b -r 235bc05ff8b1 include/linux/bootmem.h --- a/include/linux/bootmem.h Mon May 8 15:18:59 2006 +++ b/include/linux/bootmem.h Mon May 8 16:17:49 2006 @@ -41,11 +41,16 @@ struct list_head list;
