There are 4 bytes in the MSDOS master boot record, at offset 0x1b8,
which may contain a per-system-unique signature.  By first writing a unique
signature to each disk in the system, then rebooting, and then reading the
MBR to get the signature for the boot disk (int13 dev 80h), userspace may
use it to compare against disks it knows as named /dev/[hs]d[a-z], and thus
determine which disk is the BIOS boot disk, thus where the /boot, / and
boot loaders should be placed.

This is useful in the case where the BIOS is not EDD3.0 compliant, thus
doesn't provide the PCI bus/dev/fn and IDE/SCSI location of the boot disk,
yet you need to know which disk is the boot disk.  It's most useful in OS
installers.

This patch retrieves the signature from the disk in setup.S, stores it in a
space reserved in the empty_zero_page, copies it somewhere safe in setup.c,
and exports it via /sys/firmware/edd/int13_disk80/mbr_signature in edd.c.
Code is covered under CONFIG_EDD=[ym].

Replace all existing usages of __attribute__((const)) with
__attribute_const__.

'enable' is not documented in Documentation/kbuild/kconfig-language.txt So
remove usage in the only Kconfig file in the kernel tree where it was used.

- Use keyword select in relevant warning

- Include more information in warnings related to select

- Move part of error-checking to a sepearate function

- Added helpers used when issuing warnings - makes code simpler

- Wrapped most edited lines at column 80

Here's the patch to add the new _relaxed variants for PIO read accesses.
It's been ack'd by gregkh and Grant Grundler, and I think it's ready to
go.

PCI ordering rules also guarantee that PIO read responses arrive after any
outstanding DMA writes on that bus, since for some devices the result of a
readb() call may signal to the driver that a DMA transaction is complete.  In
many cases, however, the driver may want to indicate that the next readb()
call has no relation to any previous DMA writes performed by the device.  The
driver can use the readb_relaxed() for these cases, although only some
platforms will honor the relaxed semantics.

I made a few changes, basically the burst parameter is now in units of
messages, makes much more sense than the old net ratelimit one.

I also screwed up adding a sysctl_jiffies strategy for the burst parameter.

1) the version in 2.6.1 is broken, doesn't work on 64bit big endian
   machines at all.  This needed fixing.  I thought it best to fix by
   rewriting the printer/parser with an algorithm that is naturally endian &
   sizeof(long) resistant.

2) I wanted all digits to print, eg, 0000ffff,00000004 not ffff,4.

3) I wanted exactly NR_CPUS bits to print (or whatever the bitmap size is
   in bits, and not have what is displayed rounded up to the nearest full
   byte, as the current version did.

4) The bitmap printer and parser should be part of bitmap.[ch] with syntax
   and semantics to match.  The original lib/mask.c versions did not
   recognize this commonality.
