Ready for the kernel summit in Ottawa...

This also fixes it for when the real parent is ignoring
SIGCHLD - noted by David Mosberger.

For some reason I booted a NUMA and SLAB_DEBUG i386 kernel on a non
NUMA 512MB machine.  This caused an oops at bootup in change_page_attr.
The reason was that highmem_start_start page ended up zero and 
that triggered the highmem check in change_page_attr when the
slab debug code would unmap a kernel mapping.

Fix is straightforward: if there is no highmem set highmem_start_page
to max_low_pfn+1

This fixes a long standing corruption bug in the x86-64 code. The SMP
trampoline would corrupt page 2, which was sometimes used for other
data.  This corrupted the ioport/iomem list in some cases and causes
oopses while read /proc/iomem.

Fix is to check the correct location and don't zero it afterwards
because it gets reinitialized for the next CPU anyways.

Thanks to Alexander Nyberg for tracking it down.

This patch fixes a hard-to-trigger condition, where the inode is on the
inode_in_use list while it's state is dirty.  In this state dirty pages are
not written back in sync() or from kupdate, only from direct page reclaim. 
And this causes a livelock in balance_dirty_pages after a while.

The actual sequence of events required to get into this state is:

thread   function                             inode state         inode list
----------------------------------------------------------------------------
1 __sync_single_inode (background)            I_DIRTY             sb->s_io
1 do_writepages ...                           I_LOCKED
2 __writeback_single_inode (sync) sleeps      I_LOCKED
1 __sync_single_inode (background) finish     0                   inode_in_use
2 __writeback_single_inode (sync) wakeup      0
2 __sync_single_inode (sync)                  0 
2 do_writepages ...                           I_LOCKED
3 __mark_inode_dirty                          I_LOCKED | I_DIRTY
2 __sync_single_inode (sync) finish           I_DIRTY             left on
                                                                  inode_in_use

Patch for our console driver.  We converted the driver to use the serial
core functions.  Also some changes to use sysfs/udev and a new major
number.

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.

The internal interrupts are hardcoded to be level-triggered, but we need
