Theres still more to do here, but at least the ifdef mess is gone. No
more checking for NULL before calling functions, that was playing with
fire. Oh yeah and lots more deletions :)

Clean up the debugger hooks, it was way too easy to screw up.
And we did. And Linus hit it.

- create CONFIG_DEBUGGER so we can enable kernel debugging options but not
  have any trace of debugger gunk.
- remove a bunch of xmon prototypes so no one gets the urge to call them
- Use die() instead of panic in a number of places, it gives us much better
  debug information.
- Get rid of the ifdef madness

Heres a patch I've had for a while, it removes a bunch of debugger code
which is good :) The next patch will sanitise it (and the rest of the
debugger hooks).

Various xmon cleanups

- recover from bad SPR read/write (we get a program check)
- remove some old code (bat and segment register stuff)
- update the help text to match reality
- add a "press ? for help" when xmon first appears to make rusty happy
- protect against flushing bad parts of memory from Milton
- dont print iseries specific stuff on pseries in SPR dump (S)
- add code to dump the segment table or SLB
- remove a number of functions that wouldnt work on LPAR

- Add thread_info to pointer, its a useful piece of information.
- Do the kallsyms lookup on the link register
- Remove extra newline on one call to die()

Recent changes in include/linux/*.h meant that likely()
isn't defined here (since we don't set __KERNEL__), and thus
we don't get some prototypes and we can't use do_div.  This
fixes the resulting compile errors and warnings.

Remove %L handling from sprintf - we don't need it, and it
meant we needed do_div from asm/div64.h, which gives problems
when __KERNEL__ isn't defined.  Also add a prototype for
strlen to kill a warning.

into intel.com:/home/lenb/src/linux-acpi-test-2.6.3

and we do _not_ want the broken MACZILOG serial driver.

This turned what _should_ have been a nice
easy oops into a nightmare of debugging.

Kernel debuggers suck.

I missed a kfree -> framebuffer_release() in the new radeonfb.

Thanks to Luca for noticing it.

Some drivers need clear_user_page, is should be exported

This avoids a link error if PPC_PMAC is set and the user forgets to set
ADB_PMU.  (The PMU driver is mandatory for pmac)

Also update copyrights for 2004.

The following patch enhances and fixes a number of bugs in PPC44x MMU

The following patch removes some obsolete PPC4xx platforms that Paul and I
have discussed and some minor cleanup.

From: Tom Rini <trini@kernel.crashing.org>

On IBM 40x and IBM 4xx (or more specifically, all Book E processors), the
Save/Restor Registers 2 and 3 Critical Save and Restore Registers 0 and 1
are logically and functionally equivalent.  And since the 40x is the early
variant on the Book E model, make generic 4xx/BookE code refer to
CSRR0/CSRR1, and map these to SRR2/SRR3 on 40x.

- Fixup IBM Spruce support (GEN550, general fixes and cleanups).
- Forward-port the INTERACTIVE_CONSOLE bits from 2.4.
- Forward-port the bootinfo code.
- Add a weak get_mem_size() function.

Some stage in reiserfs balancing (fix_nodes() function) has to be performed
without ever scheduling.  If it schedules, it has to be restarted.  As we
don't want to restart often, we first try to do atomic allocation, and if
it fails, GFP_NOFS allocation is done, and fix_nodes() restarted.

The len parameter for fadvise has a signed type and negative values passed
must be rejected.  The attached patch does the job.

From: Bjorn Helgaas <bjorn.helgaas@hp.com>

The current serial console code only works for ports that are either
defined in SERIAL_PORT_DFNS (and set up by serial8250_isa_init_ports()) or
registered by early_serial_setup().

On ia64, SERIAL_PORT_DFNS is empty because we discover everything via ACPI
and PCI.  And we only use early_serial_setup() for one port described by
the HCDP firmware table.

This patch against 2.6.3-rc2 makes it work for any valid port.  If we don't
know about the port early, we just return -ENODEV from the setup()
function, which leaves the serial console disabled.  After the driver has
found all the ports, we try to register the serial console again if it
hasn't been enabled already.

I think the "port->type == PORT_UNKNOWN" test is cleaner than the
"port->ops" test -- it more clearly gets to the point of "do we know about
this port".

Fix a screwup in the merging of swap extents: not only do they have to be
contiguous on-disk, they have to be logically contiguous in file offset too.

From: Ivan Kokshaysky <ink@jurassic.park.msu.ru>

Again...  This time due to pci.h->dmapool.h->io.h included in core logic
files before __EXTERN_INLINE definition.

To prevent such troubles in the future, make io.h/core_xx.h included before
anything else.  Also, this allows to get rid of some duplicated #include's.

Sanity fixes in pvr2fb_check_var() so we don't constantly report an invalid
pixclock..  also fixup FB_SYNC_BROADCAST setting so this doesn't get
improperly assigned in the VO_VGA case.

From: Paul Mundt <lethal@linux-sh.org>

This updates hitfb, and also adds basic accel support.  Also as we don't need
the generic cfb_copyarea anymore, we no longer link cfbcopyarea.o in at build
time.

From: Paul Mundt <lethal@linux-sh.org>

This adds sh to the list of platforms that wrap fb_readX/fb_writeX() to
__raw_readX/__raw_writeX().  This is needed so that the generic fb read/write
routines will wrap properly through the sh machvec and use the appropriate
board-specific I/O routines.

This patch fixes a couple of bugs in the SELinux policy loading code.  The
first bug was reported by Magosanyi Arpad; kernel panic upon feeding the
kernel a policy with an empty avtab due to cleanup code trying to free the
avtab twice.  The other bugs were reported by Frank Mayer; failure to
properly validate certain values read from the policy.
