free_irq() should not be executed from softirq context.
Found by the lock validator. The fix is to push fd_free_irq() into
keventd. The code validates fine with this patch applied.

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.

In latest -mm a number of section mismatch warnings are generated for
floppy.o like the following:
WARNING: drivers/block/floppy.o - Section mismatch: reference to \
.init.data: from .text between 'init_module' (at offset 0x6976) and \
'cleanup_module'
The warning are caused by a reference to floppy_init() which is __init from
init_module() which is not declared __init. Declaring init_module() _init
fixes this.

We need set_page_dirty() to return true if it actually transitioned the page
from a clean to dirty state. This wasn't right in a couple of places. Do a
kernel-wide audit, fix things up.
This leaves open the possibility of returning a negative errno from
set_page_dirty() sometime in the future. But we don't do that at present.

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
