Make the ramdisk blocksize configurable at kernel compilation time rather
than only at boot or module load time, like a couple of the other ramdisk
options. I found this handy awhile back but thought little of it, until
recently asked by a few of the testing folks here to be able to do the same
thing for their automated test setups.
The Kconfig comment is largely lifted from comments in rd.c, and hopefully
this will increase the chances of making folks aware that the default value
often isn't a great choice here (for increasing values of PAGE_SIZE, even
moreso).

The FRV arch doesn't currently support initrd, so it should be disabled
automatically for the moment.

It's purely cosmetic, but with the patch there's no longer a
BLK_DEV_RAM_COUNT setting in the .config if BLK_DEV_RAM=n.

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.

Allocate memory for read-gathering at open time, when it is known just how
much memory is needed. This avoids wasting kernel memory when the real packet
size is smaller than the maximum packet size supported by the driver. This is
always the case when using DVD discs.

This patch adds a shim driver libusual, which routes devices between
usb-storage and ub according to the common table, based on unusual_devs.h.
The help and example syntax is in Kconfig.

drivers/block/ is right now a mix of core and driver parts. Lets move
the core parts to a new top level directory. Al will move the fs/
related block parts to block/ next.

Sanitized and fixed floppy dependencies: split the messy dependencies for
BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making
BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC
to arch/*/Kconfig. While we are at it, fixed several obvious cases when
BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h
are *not* going to have floppy.c compile, let alone work).
If you can come up with better name for that ("this architecture might
have working PC-compatible floppy disk controller"), you are more than
welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch
below...

This is a more natural place for this option.

(!ARCH_S390 && !M68K && !IA64 && !UML) is obviously always true on ARM.
Intended behaviour for ARM is "absent unless we are on RiscPC or
EBSA285". So what we want is added && !ARM in the first term - without
it the last part (|| ARCH_RPC || ARCH_EBSA285, that is) doesn't do
anything.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
