s390 general update:

- Add archhelp for "make image".

- 32-bit execve fix.

- Export some symbols: sys_ioctl, put_files_struct & ccw_device_work.

- Minor cleanups in arch/s390/mm/init.c & drivers/s390/net/ctctty.c.

These are some trivial cleanups to the hugepage ppc64 support

The current SLB handling code has a number of problems:

- We loop trying to find an empty SLB entry before deciding to cast one
  out.  On large working sets this really hurts since the SLB is always full
  and we end up looping through all 64 entries unnecessarily.

- During castout we currently invalidate the entry we are replacing.  This
  is to avoid a nasty race where the entry is in the ERAT but not the SLB and
  another cpu does a tlbie that removes the ERAT at a critical point.  If
  this race is fixed the SLB can be removed.

- The SLB prefault code doesnt work properly

The following patch addresses all the above concerns and adds some more
optimisations:

- feature nop out some segment table only code

- slb invalidate the kernel segment on context switch (avoids us having to
  slb invalidate at each cast out)

- optimise flush on context switch, the lazy tlb stuff avoids it being
  called when going from userspace to kernel thread, but it gets called when
  going to kernel thread to userspace.  In many cases we are returning to the
  same userspace task, we now check for this and avoid the flush

- use the optimised POWER4 mtcrf where possible

Lets make a decent attempt to find out where your console is.  The new
preferred_console stuff is pretty nice.

Small obvious fix to ppc32_timer_create.  Since sys_timer_create access
structures we pass on the stack, we need set_fs(KERNEL_DS).

- nop out proc_device_tree_add_node if CONFIG_PROC_DEVICETREE=n

- stubs for procfs-related functions when CONFIG_PROC_DEVICETREE=n

Add lparcfg_write() for changing SPLPAR system parameters

From: Anton Blanchard <anton@samba.org>

add missing include guards, from Nathan Lynch

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

Correct the defines for MC146818 RTCs, reg c is interrupts, reg d is not
watchdog (it's valid time & nvram).

This forward ports a few important fixes from the 2.4 driver.  This
changes have been well tested.

Changelog:
 - Update maintainer email address
 - Mark pci_device_id list with __devinitdata.
 - Set correct protocol type on packet receive (this caused the kernel to
   drop all packets received)
 - Add #ifdef DEBUG around debug printk()
 - ioctl: Add missing size checks before
   copying data from userspace.

We used to have code to allow binaries linked against glibc to run,
when glibc itself contained some FP instructions (for PCS stack
frames for functions like printf and scanf) thereby allowing FP
emulators like nwfpe to be built as modules.

This has proved to be unreliable with later compilers, so support
for this was dropped a while ago.  Since no one complained, we can
finally remove the dead code.

(NB. a klibc based module-init-tools shouldn't suffer from this
problem.)

According to x86, the pointers for bitops are supposed to be
qualified with volatile.  Make ARM bitops reflect this.

Remove usage of tsk->used_math on ARM, moving the status to an array
of co-processor usage.  (ARM can have up to 15 co-processors
providing various extra facilities such as SIMD, VFP or FP.)

Jakub points out that having an automatic array is not only
bad for performance (and stack usage), gcc has also historically
had lots of bugs here, and gcc-3.2.3 seems to miscompile it
otherwise.

This fixes some issues in the dvb subsystem and some nasty things in the
v4l saa7146 driver.

[DVB]
 - dvb-core: aquire -> acquire spelling fix
 - nxt600 frontend: don't send zero-byte messages when probing the PLL
   type
 - Kconfig: add a note that says that the CI of the budget-CI card is
   not actually supported by the budget-CI driver
 - ttusb-dec: Check for presence of crc32 function.  Make unknown types
   of packet less likely to cause packet loss.

[V4L]
 - saa7146: use kernel mint_t()/max_t() instead of homebrewn stuff
 - saa7146: disable video clipping before capturing for sure to prevent
   black pictures
 - saa7146: make sure to disable the right video dma upon device close
 - saa7146: don't free resources if disabling an already disabled video
   overlay

This is a simple fix for some of the problems with bad ACPI frequency values:

  Abort if the frequency field in _PSS is zero, as we're having a
  completely broken ACPI table then.

A more complete overhaul of the acpi-cpufreq driver (where the cause of
the problem lies) is in the latest acpi-test tree, but that's definitely
something to be delayed for 2.6.3 -- and the same is true for the
yet-to-be-written do_div64 conversion.

This fixes my APM problems (without them my laptop, Acer TravelMate
210TEV (Celeron 700, 128 MB RAM), hangs after resuming from APM since
2.6.0-test4).

Modified based on comments from Pavel Machek <pavel@suse.cz>, who
has acked the updated patch.
