Modify well over a dozen mempool users to call mempool_create_slab_pool()
rather than calling mempool_create() with extra arguments, saving about 30
lines of code and increasing readability.

This patch changes several mempool users, all of which are basically just
wrappers around kmalloc(), to use the common mempool_kmalloc/kfree, rather
than their own wrapper function, removing a bunch of duplicated code.

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.

He/she must be a retrocomputing geek, who can easily bias it to usb-storage
