The mv643xx_eth driver is being modified to support multiple instances
of the ethernet silicon block on the same platform.  Each block contains
a single register bank containing the registers for up to three ports
interleaved within that bank.  This patch updates the PowerPC OF to
platform_device glue code to support multiple silicon blocks, each
with up to three ethernet ports.  The main difference is that we now
allow multiple mv64x60_shared platform_devices to be registered and
we provide each port platform_device with a pointer to its associated
shared platform_device.  The pointer will not be used until the
mv643xx_eth driver changes are committed.

If an SLB miss interrupt happens while the RI bit of MSR is zero, we
can't just return, because RI being zero indicates that SRR0/SRR1
potentially had live values in them, and the process of taking an
interrupt overwrites them.

This should never happen, but if it does, we try to print a nice oops
message.  That doesn't work, however, because the code at unrecov_slb
assumes that the MMU has been turned on, but we call it with the MMU
off (and have done so since the SLB miss handler was rewritten to run
without turning the MMU on) -- except on iSeries, where everything runs
with the MMU on.

This fixes it by adding the necessary code to turn the MMU on if
necessary.

Increase the PNP "number of devices" limit.  We currently use an unsigned
char, which limits us to 256 devices per protocol.  This patch changes that to
an unsigned int.

Not all backends can take advantage of this: we limit ISAPNP to 10 devices in
isapnp_cfg_begin(), and PNPBIOS is limited to 256 devices because the BIOS
interfaces use a one-byte device node number.

But there is no limit on the number of PNPACPI devices we may have.  Large HP
Integrity machines have more than 256, which causes the current "unsigned char
number" to wrap around.  This causes errors like this:

    pnp: PnP ACPI init
    kobject_add failed for 00:00 with -EEXIST, don't try to register things with the same name in the same directory.

    Call Trace:

     [<a0000001007f2810>] pnpacpi_add_device_handler+0x50/0x80

This patch increases the limit to fix this PNPACPI problem.  It should not
have any adverse effect on ISAPNP or PNPBIOS because their limits are still
enforced in the backends.

Extend the /proc/<pid>/cgroup file to include the appropriate hierarchy ID on
each line.

Currently this ID isn't really needed since a hierarchy can be completely
identified by the set of subsystems bound to it, but this is likely to change
in the near future in order to support stateless subsystems and
merging/rebinding of subsystems.  Getting this change into 2.6.25 reduces the
need for an API change later.

It's really a pretty ugly thing to need, and some day it will hopefully
be obviated by teaching gcc about the magic calling conventions for the

honking comments about why we need these insane and strange macros.

I took my comments from my version of the macro, but I ended up deciding
to just pick Roland's version of the actual code instead (with his
prettier syntax that uses vararg macros).  Thus the previous two commits

Use asmlinkage_protect in sys_io_getevents, because GCC for i386 with
CONFIG_FRAME_POINTER=n can decide to clobber an argument word on the
stack, i.e. the user struct pt_regs.  Here the problem is not a tail
call, but just the compiler's use of the stack when it inlines and
optimizes the body of the called function.  This seems to avoid it.
