Now that Linus' tree has the new sn2 console driver, make sn2_defconfig enable 
it by default.  The device is major 204, minor 40.  Note that you'll probably 
have to update your elilo.conf and inittab to use the new driver, as it's 
called ttySG0 rather than ttyS0.

This patch fixes a potential kernel hang in perfmon during
PFM_UNLOAD_CONTEXT.  This commands requires that the monitored task be
stopped (except when self-monitoring). The task state tests in
check_task_state() were incorrect and an actively running task was
accepted for PFM_UNLOAD_CONTEXT. This eventually leads to a kernel
hang.

We already get this info in other forms from other boot messages, so kill the 
printing of the MADT entries as they're parsed.  This patch significantly 
reduces the amount of output from a boot of a 512p system.

partially annotated, fixed dereferencing of userland pointer (trivial,
since we'd just copied the entire structure).

Massive, but trivial - drm annotated and got 0->NULL where needed.  That
patch kills ~2200 lines of warnings - out of 5400 that remained at that
point.

the rest of iovec cleanups: nbd, dvb-net, sock.c::sock_no_sendpage(),
econet over udp and ip_vs switched to use of kvec and kernel_...msg().

sunrpc, nfs and nfsd switched to use of kvec and kernel_...msg()

rxrpc (low-level part of afs) switched to kernel_...msg(); it already was
using kvec instead of iovec.

cifs switched to kvec and kernel_...msg()

ncpfs switched to kvec and kernel_...msg()

smbfs switched to kvec and kernel_...msg()

Beginning of iovec cleanups - added two helpers (kernel_{send,recv}msg)
that do sock_sendmsg/sock_recvmsg with kvec instead of iovec; basically,
they were abstracted from earlier afs patch.  They take kvec/length of
kvec as separate arguments, do set_fs(), stick kvec into msghdr and call
sock_...msg(). 

The next group of patches will switch network filesystems to use of kvec
for kernel data + use of these helpers.  Basically, the same thing we'd
done for afs.

switched to compat_alloc_user_space(), cleaned up.

 - missing ; between default: and } in sun4setup.c
 - cast of pointer to unsigned long long instead of unsigned long in
   x86_64 signal.c
 - missed annotations for ioctl structure in sparc64 openpromio.h
   (should've been in the same patch as the rest of drivers/sbus/*
   annotations)
 - 0->NULL in list.h and pmdisk.c

A bunch of drivers are broken on sparc64; mark them as such in Kconfig.
arlan and smctr are not 64bit-clean; again, markes as such.

The au88x0 driver tries to use the wrong private field - there are two,
one of them int and another void *.

While it's not a problem on 32bot boxen, it breaks on 64bit ones. 

Fixed.

This works around the current PROT_NONE problem from elf binaries that
do not have the PT_GNU_STACK so that the do not have execute permission.

The problem was that setting "def_flags" to include the VM_EXEC bit for
compatibility reasons would also make PROT_NONE pages executable, which
is obviously not correct.

I got sidetracked (I do that a lot ;-) and noticed that there are only
eight files in 2.6 that have code like:

#ifdef MODULE_PARAM
MODULE_PARAM(foo, "i");
#endif

which I think is old cruft from 2.1.x times.  Following patch removes
all those eight (six in netfilter, one net driver and one SCSI driver).

Writing to RAM capable media was broken by the moving of write flag
detection from probe to drive open time.  The media would stay
terminally RO due to the set_disk_ro() call. 

This fixes the code to do the right thing - the detection stays at open
time (which it must, since it depends on the media), and we fail with
-EROFS if the media can't be written.

If nobody shouts soon about why the new, shiny, generic chip drivers 
don't work where the old ones do, they can be removed entirely.

and fix a few compiler warnings while we're at it.

It wants reimplementing sanely, preferably in sysfs instead.

This fixes the PPC openpic driver to use cpumask_t where appropriate.

The internal interrupts are hardcoded to be level-triggered, but we need
to make sure the OpenPIC code knows that...

The UART tristates its IRQ output when the OUT2 bit in the MCR isn't
set. For reasons not known to civilised man, the hardware engineers
stopped it from floating by pulling it _high_ instead of low, so if
anybody requests that IRQ before OUT2 is turned on, we die in an IRQ
storm. The serial8250 driver does precisely that thing, with precisely
that effect.

ALPHA_KLUDGE_MCR was designed to fix exactly this kind of problem, so we
use it here as intended. Ideally ALPHA_KLUDGE_MCR would go away and be
replaced with something like UPF_FORCE_OUT2 and UPF_FORCE_OUT1 flags,
but now is not the time to get me started on a cleanup of everything
about serial8250 that offends me.

The UART is detected as a ST16650V2 but its FIFO doesn't behave nicely.
Disable autoprobe and hard-code it to be a ST16650 instead.

Just unearthed another of my warcrimes: reading a 17-page sparse file,
I mean holey file, hits the in_interrupt panic in do_exit on a current
highmem kernel (but 2.6.7 is okay).  Fix mismatched preempt count from
shmem_swp_alloc's swapindex hole case by mapping an empty_zero_page.
