Rename _bss to __bss_start as on other architectures.  That makes it
possible to use the <linux/sections.h> instead of own declarations.  Also
add __bss_stop because that symbol exists on other architectures.

With the unionfs patch applied I get

ERROR: "copy_page" [fs/unionfs/unionfs.ko] undefined!

the other architectures (some, at least) export copy_page() so I guess ia64
should also do so.

To do this we need to move the copy_page() functions out of lib.a and into
built-in.o and add the EXPORT_SYMBOL().

This driver for HPQ5001 devices installs a global ACPI OpRegion handler.
AML methods can use this OpRegion to call native firmware entry points.

ACPI does not define a mechanism for AML methods to call native firmware
interfaces such as PAL or SAL.  This OpRegion handler adds such a mechanism.
After the handler is installed, an AML method can call native firmware by
storing the arguments and firmware entry point to specific offsets in the
OpRegion.  When AML reads the "return value" offset from the OpRegion, this
handler loads up the arguments, makes the firmware call, and returns the
result.

Every user of the network device notifiers is either a protocol
stack or a pseudo device.  If a protocol stack that does not have
support for multiple network namespaces receives an event for a
device that is not in the initial network namespace it quite possibly
can get confused and do the wrong thing.

To avoid problems until all of the protocol stacks are converted
this patch modifies all netdev event handlers to ignore events on
devices that are not in the initial network namespace.

As the rest of the code is made network namespace aware these
checks can be removed.

This patch cleans up the `enable early console for SKI' patch
(471e7a44), and
1. potentially allows the gensparse_defconfig to work again.
   (there are other problems running a generic kernel on Ski)
2. fixes the `console registered twice' problem.
3. Cleans up the code by moving the `extern hpsim_cons' declaration to
   a new asm/hpsim.h file.

On HP zx1 machines, the 'machvec=dig' parameter is needed for the
kdump kernel to avoid problems with the HP sba iommu.  The problem
is that during the boot of the kdump kernel, the iommu is re-initialized,
so in-flight DMA from improperly shutdown drivers causes an IOTLB
miss which leads to an MCA.  With kdump, the idea is to get into the
kdump kernel with as little code as we can, so shutting down drivers
properly is not an option.

The workaround is to add 'machvec=dig' to the kdump kernel boot
parameters.  This makes the kdump kernel avoid using the sba iommu
altogether, leaving the IOTLB intact.  Any ongoing DMA falls
harmlessly outside the kdump kernel.  After the kdump kernel reboots,
all devices will have been shutdown properly and DMA stopped.

This patch pushes that functionality into the sba iommu
initialization code, so that users won't have to find the obscure
documentation telling them about 'machvec=dig'.

This patch only affects HP platforms.  It still includes one
extern declaration in the file, because no applicable header file
exists.

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

As part of an SMP cleanliness pass over UML, I consted a bunch of
structures in order to not have to document their locking.  One of these
structures was a struct tty_operations.  In order to const it in UML
without introducing compiler complaints, the declaration of
tty_set_operations needs to be changed, and then all of its callers need to
be fixed.

This patch declares all struct tty_operations in the tree as const.  In all
cases, they are static and used only as input to tty_set_operations.  As an
extra check, I ran an i386 allyesconfig build which produced no extra
warnings.

53 drivers are affected.  I checked the history of a bunch of them, and in
most cases, there have been only a handful of maintenance changes in the
last six months.  serial_core.c was the busiest one that I looked at.
