2006-04-17[PATCH] cciss: bug fix for crash when running hpacucliMike Miller
Fix a crash when running hpacucli with multiple logical volumes on a cciss controller. We were not properly initializing the disk->queue and causing a fault. Thanks to Hasso Tepper for reporting the problem. Thanks to Steve Cameron for root causing the problem. Most of the patch just moves things around. The fix is a one-liner.

2006-03-31[PATCH] Don't pass boot parameters to argv_init[]OGAWA Hirofumi
The boot cmdline is parsed in parse_early_param() and parse_args(,unknown_bootoption). And __setup() is used in obsolete_checksetup(). start_kernel() -> parse_args() -> unknown_bootoption() -> obsolete_checksetup() If __setup()'s callback (->setup_func()) returns 1 in obsolete_checksetup(), obsolete_checksetup() thinks a parameter was handled. If ->setup_func() returns 0, obsolete_checksetup() tries other ->setup_func(). If all ->setup_func() that matched a parameter returns 0, a parameter is seted to argv_init[]. Then, when runing /sbin/init or init=app, argv_init[] is passed to the app. If the app doesn't ignore those arguments, it will warning and exit. This patch fixes a wrong usage of it, however fixes obvious one only.

2006-03-25[PATCH] BLK_DEV_INITRD: do not require BLK_DEV_RAM=yZdenek Pavlas
Initramfs initrd images do not need a ramdisk device, so remove this restriction in Kconfig. BLK_DEV_RAM=n saves about 13k on i386. Also without ramdisk device there's no need for "dry run", so initramfs unpacks much faster. People using cramfs, squashfs, or gzipped ext2/minix initrd images are probably smart enough not to turn off ramdisk support by accident.

Matt mentioned that a very old ZIP-100 actually does need this, but I am yet to see anyone who actually has one still working and uses ub with it. He/she must be a retrocomputing geek, who can easily bias it to usb-storage with libusual, if needed.
