2.2.19pre3 on sparc64: Hangs on boot, "no cont in shutdown!"??

2.2.19pre3 on sparc64: Hangs on boot, "no cont in shutdown!"??

[Horst von Brand]

Red Hat 6.2 + updates (plus local hacks, like binutils-2.10.0.33) on
sparc64 (Ultra 1).

When booting, it detects the floppy drive (I left a floppy in by mistake,
the floppy is OK, and the same boots fine with 2.2.18):

  [snip snap]
  Floppy drive(s): fd0 is 1.44M

after this, it just gives the "no cont in shutdown!" message after a few
seconds, and stays stuck AFAICS (not much patience, I'm afraid). This
message is inside drivers/block/floppy.c:floppy_shutdown(), a file that
hasn't changed from 2.2.18 to 2.2.19pre3.

BTW, the floppy here (and also on sparc32) normally gives:

  $ mdir
  init: set default params
  Cannot initialize 'A:'

the first time around, the second time it works OK. A too short timeout in
mtools or in the kernel perhaps?

"make check_asm" should fix it.

It doesn't work out of the box starting from pre3 because there are a
few fields in the task struct implemented this way:

	struct list_head local_pages; int allocation_order, nr_local_pages;

that is perfectly valid C code but I wasn't aware of the check_asm.sh sed
script assumptions and so I incidentally broke sparc's `make check_asm', sorry.
To make my 2.2.x tree to work on sparc64 I temporarly broken the above line in
two for the time of `make check_asm'. I guess we can go with this patch for
2.2.x instead of doing the right fix ;)
