M68k floppy: Kill warnings when compiling a multi-platform kernel

Ns558 gameport: constness of ns558_pnp_driver depends on CONFIG_PNP, causing a
warning if CONFIG_PNP is not set, so make sure it is never const.

	bypassing on again, which is more beneficial, performance-wise.

<asm-v850/setup.h> is not correct, and not used, so remove it.

This renames ->cluster_size to ->sec_per_clus. Old ->cluster_size was
"sectors per cluster". Adds a _real_ ->cluster_size.

This changes a few more char type of filenames to unsigned char.

This uses the new fat_get_cluster() in fat_free(), fat_calc_dir_size()
and fat_add_cluster().

This uses the new fat_get_cluster() in fat_bmap_cluster().  Another part
removes an unneeded error check of fat_get_entry() by using
fat_get_cluster().

This adds fat_get_cluster() for generic reads of FAT cluster-chains, and
old fat_get_cluster() is renamed to fat_bmap_cluster().

This reads ->free_clusters without lock_fat() in fat_statfs().

This removes the dump_fat() and dump_de() obsoleted debug code in
vfat/namei.c.

This removes dirty raw_scan_*(), and rewrites fat_scan() and
fat_subdirs() to use fat_get_entry() instead.

This fixes filename case handling in vfat_revalidate():

before:
	# mount -t vfat /dev/hda6 /mnt -o shortname=winnt
	# cd /mnt
	# cat File.Txt			# make negative dentry
	cat: File.Txt: No such file or directory
	# touch file.txt		# match negative dentry
	# ls
	File.Txt

after:
	# mount -t vfat /dev/hda6 /mnt -o shortname=winnt
	# cd /mnt
	# cat File.Txt			# make negative dentry
	cat: File.Txt: No such file or directory
	# touch file.txt		# match negative dentry
	# ls
	file.txt

This adds a forgotten check of MS_RDONLY flag to fat_put_super(), and
adds sanity check of ->free_clusters and ->prev_free to fat_cluster_flush().

    - check the ioctl cmd first
    - check the directory whether it's an already dead

incorrect re-declaration of the internal linker
symbols.

It doesn't really make sense for udp.

This fixes a *very* obscure bug, which only applies to VIA chipsets that
support UDMA-133 mode, and which is only known to be tickled by one
UDMA-66 hard drive (Maxtor 91360U4) that happens to report 80-wire cable
detection opposite to the ATA standard.

The bug appears in a test to see how the BIOS set up UDMA timing.  This
test is only reached when the drive says 80-wire *and* the chipset says
40-wire (which is only known to happen with this drive).

The timing bits that are checked represent clocks T minus 2, i.e., ((N -
2) * T).  But Vojtech forgot to subtract 2, and applied N = 8 rather
than N = 6 in the test.  Since the test masks the bits at 7, they are
always less than 8, and the test always succeeds, even though the BIOS
set UDMA-33.

This allows SCSI to survive the I/O queueing stress harness with AS.

Jens has signed off on it, and Mark Havercamp confirms it also
eliminates the test induced hangs for him too.

Update support for .incbin in /usr. No longer generate .S files
from within the Makefile.

Also deleted the assignment to LDFLAGS_BLOB for most architectures.
I did not touch ARM and cris:
 arm: Russell told me they did not have a new as that could be used
 cris: Looked like it was used for more than just usr/

Simplify Makefiles in fs/ by utilising the new syntax for composite
objects. The new syntax allowed a couple of ifeq ($(CONFIG_FOO),y)
to be deleted, resulting in more readable Makefiles.

No functional changes introduced.

Patch by Herbert Xu <herbert@gondor.apana.org.au>:

As of 2.5.74, make oldconfig always disables existing optional choices
even if they were selected previously.  For example, if all the EICON
ISDN drivers were selected as modules, then make oldconfig will turn
them off.

Part of the problem is that the choice value itself is computed before
the SYMBOL_NEW flag is turned off.  This patch addresses that particular
problem.

During an erlier update the call to generate the .config dependency
got lost.
Add a missing warning.

correctly select a nested menuconfig entry

Patch by Romain Lievin <roms@tilp.info>
various fixes to handle menuconfig options

A spinlock was recently added to struct skmca_priv so as to remove
save_flags()/cli() but nothing in the current code initializes it.

This updates generic HDLC from 1.14 to 1.15.

 - fix a kernel panic caused by a recent change to unregister_netdevice()
   (struct net_device * can't be kfreed before rtnl_unlock())
 - adds carrier_* support - hw drivers report DCD status and higher level
   protocols use that info, and do netif_carrier_{on,off}() according to
   DCD and (Cisco and FR) link management status.
 - moves Frame-Relay constants etc. from include/linux/hdlc.h to hdlc_fr.c.
   They are internal FR things and are not needed in the global header.
 - protocol hooks are slighty changed to allow zeroing (memset).
 - removes CONFIG_HDLC_DEBUG_* variables. Users tend to make very wrong
   use of them. Now setting them requires changing .c #define. Anyway they
   are development-only things.
 - misc style corrections etc.
