Doug Gilbert and James Bottomley hassled me all through KernelSummit &
OLS to explain about softirqs, tasklets and bottom halves.  In the end,
it was easier to write the code myself.  Thanks to James for pointing
out that the pointer handling in my original code was completely broken
and helping me debug.

I've booted this patch on a 4-way system at OSDL with two Adaptec SCSI
cards.  I haven't tried stressing it (not quite sure which discs I can
use ;-), and I don't understand the locking in the scsi subsystem at all.

The main effect of applying this patch is that scsi_softirq() [was
scsi_tasklet_func, and before that scsi_bottom_half_handler()] can now be
run on multiple CPUs at the same time.  We _seem_ to do enough locking
elsewhere in the SCSI stack that this is safe.  But someone who really
understands the SCSI stack should audit this.

This work shows up a hole in the current softirq API -- there's no support
for unregistering a softirq (close_softirq or similar).  We should do
this in scsi_exit -- make sure no softirqs are running while we unload.
This probably isn't a problem in practice, but it'd be nice to fix it.

The last changes did trigger another latent bug in the inline assembly.
akpm noticed it because he compiles his kernels with frame pointers.

into home.transmeta.com:/home/torvalds/v2.5/linux

Uninline elv_next_request() and move it to elevator.c, where it belongs.
Because of CURRENT declaration, this actually saves lots of space.  From
Andrew.

init_rootfs() (from ramfs) doesn't appear in any header file.  I didn't
see any that looked like a good home, so lets put a prototype at the top
of fs/namespace.c.  This only use of this function is in namespace.c.

This patch makes sure the 3c509 module license is always GPL.  Currently
the MODULE_LICENSE() marco is only used when CONFIG_ISAPNP or
CONFIG_ISAPNP_MODULE is defined.  I have moved MODULE_LICENSE() to the
#ifdef MODULE section at the bottom of 3c509.c.

Same is true for the MODULE_DEVICE_TABLE() macro.

Not sure why I forgot to do this, but here is a small bit of tidying up
of some leftover parentheses from the memlist macro removal. The
parentheses are just noise and should go.

page_alloc.c does not use either slab.h or swapctl.h. This removes the
inclusion of those headers from page_alloc.c

nr_free_pages() is overly verbose. The following is perhaps clearer and
gets to the point with fewer lines of code and inside of 80 columns.

14 of our 17 architectures define sys_pause exactly the same
way.  The other three don't define it at all.  I assume glibc
translates pause() into sigsuspend() or something.

In favour of those now in kernel.h..

Three arch-determining symbols in drivers/mtd/maps/Config.in are wrong.
They have apparently been generated using the sensible pattern "CONFIG_FOO"
for an architecture "foo"; unfortunately the architectures are not sensible.

  CONFIG_SPARC should be CONFIG_SPARC32
  CONFIG_I386 should be CONFIG_X86
  CONFIG_SH should be CONFIG_SUPERH

Removed a spurious menu definition which was both a duplicate and
had no matching "endmenu".

Removed an "endmenu" for which there was no opening "mainmenu_option".

The config language is *not* shell.  The construct "[ foo ] || [ bar ]"
is legal in shell but not in the config language, where we should use
the equivalent "[ foo -o bar ]"

The format for the "choice" statement is:

  choice 'prompt' "{sub-prompt sub-symbol}*" default-value

and the following is *not* legal config language (note the
positioning of the closing double quote):

  choice 'prompt' "{sub-prompt sub-symbol}* default-value"

It only happens to work because of a combination of accidental
side effects of the current parsers:

  *   unpaired sub-words inside the 2nd word are silently ignored
  *   the missing last word is silently treated as if empty

Two symbols used in drivers/net/wan/Config.in are misspelled.

CONFIG_PPP_MULTLINK should be CONFIG_PPP_MULTILINK
CONFIG_PPP_SYNCTTY should be CONFIG_PPP_SYNC_TTY
