makes sure a possible (never happened, but just in case) infinite
loop in the transmission code terminates.

changes the card shutdown sequence to a safer one

also detach the threads.

Otherwise we'll leave them around as zombies, waiting for them
to be picked up by their parent. Which might be the execve()
thread itself, causing a deadlock.

Noted by Sean Estabrooks:

There is a bug in "ll_rw_blk.c" handling partial bvec submissions.
For whatever reason the floppy driver was triggering it more than
other users (most likely because most other devices tend to be able
to always complete a full request in one go).

Fixed by updating the proper bio vector index entry.

Add kconfig options to allow excluding either or both the I/O
schedulers.  This can be useful for embedded systems (saves about ~13KB).

All schedulers are enabled by default for non-embedded.

This updates the valkyriefb driver to the new API.

From Paul Mackerras <paulus@samba.org>:

 "It compiles OK, but I haven't been able to test it.  I have simplified
  the driver quite a bit using the knowledge that there can only ever be
  one valkyrie graphics adaptor in a system - it is the built-in
  graphics adaptor on various ancient mac and powermac machines, and we
  access it at a hard-coded address, so we can only handle one."

Documentation/nmi-watchdoc.txt doesn't actually tell what options need to be
enabled in kernel config in order to use NMI watchdog. I for one found it
confusing.

Rename ariadne2 to zorro8390, since this driver supports several NS8390-based
Zorro Ethernet cards. Kill all never used occurrencies of CONFIG_NE2K_ZORRO.

m68k cache updates (from Roman Zippel):
  - Uninline flush_icache_range()
  - Add virt_to_phys_slow() which handles vmalloc()ed space

M68k: Use genrtc on all m68k platforms

M68k: Allow ALLOWINT to be used with other types than short (fixes a problem
with irqs_disabled(), from Roman Zippel)

dmasound: Implement missing SOUND_PCM_READ_RATE ioctl (from Richard Zidlicky)

MIPS: Show the correct logo on DEC and SGI machines.

M68k FPU emulator: Add fgetman, fgetexp and fsqrt (from Michael Müller and
Roman Zippel)

M68k: A few missing updates to the new irq API:
  - Q40/Q60 keyboard
  - Q40/Q60 floppy
  - Sun-3x floppy

m68k page updates (from Roman Zippel):
  - Set _PAGE_RONLY bit and clear _PAGE_PRESENT to mark PAGE_NONE pte entries
    (this also makes PAGE_NONE fixup unnecessary)
  - Move _PAGE_FILE to a lower, so pte_to_pgoff/pgoff_to_pte becomes simpler

NCR53C9x: Remove unused initialization of SCp.have_data_in (from Maciej W.
Rozycki). This affects the following drivers:
  - DECstation SCSI
  - Amiga Oktagon SCSI

Macfb compile fixes

M68k: Add missing include for IPV6

M68k: Update for changed do_fork() semantics in 2.5.70

M68k: Fix SCSI breakage introduced in 2.5.74 by not including
<asm-generic/dma-mapping.h>, unless PCI is available.

M68k: show_stack() portability and cleanup patch:
  - Add a task pointer argument to show_stack() and pass NULL as the first
    argument where needed
  - Remove show_trace_task()

Sun-3 SCSI: Kill a warning about a nonmatching prototype after recent SCSI
proc_info() changes.

lmc_proto.c includes <asm/smp.h>, causing build failures on UMP-only
architectures

Atari ksyms: Kill obsolete symbol exports

M68k: Kill superfluous includes

mach_floppy_setup function pointers

again in 2.5.71)
