[PATCH] ppc64: Convert mm_context_t to a struct
From: David Gibson <david@gibson.dropbear.id.au>
Converts the mm_context_t on ppc64 to be a struct. This lets us separate
the low_hpages flag into a separate field rather than folding it into the
actual context id. That makes things neater, since the flag is
conceptually separate and has, for example, should be propogate across a
fork whereas the context ID obviously isn't. The mm_context_id is the only
place to put arch-specific information in the mm_struct.
This patch will also make some interesting extensions to the hugepage
support much easier, such as allowing dynamic resizing of the hugepage
address space, or using special pagetables for hugepages.

[SERIAL] Make serial console work for any port (take 2)
The current serial console code only works for ports that are either
defined in SERIAL_PORT_DFNS (and set up by serial8250_isa_init_ports())
or registered by early_serial_setup().
On ia64, SERIAL_PORT_DFNS is empty because we discover everything
via ACPI and PCI. And we only use early_serial_setup() for one port
described by the HCDP firmware table.
This patch against 2.6.4-rc1 makes it work for any valid port. If we
don't know about the port early, we just return -ENODEV from the
setup() function, which leaves the serial console disabled. After the
driver has found all the ports, we try to register the serial console
again if it hasn't been enabled already.
Keith Owens noticed that the first version of this patch broke some
serial console setups because many early serial ports are registered
with "type == PORT_UNKNOWN". So this version tests "port->ops"
instead, and Keith has confirmed that this works for him.

to BE since that's what I mostly work with) so this patch forces
endianess options to be passed to the toolchain. W/O this,
building without CONFIG_CPU_BIG_ENDIAN on a big-endian toolchain

New revision of the Sigmatel irda driver. This version has much
better performance and doesn't drop frames in FIR mode.
Tested with both UHCI and EHCI/OHCI against nsc-ircc on laptop.
Thanks to Martin for additional testing and feedback.
* Receiver:
- changed from interrupt to bulk URB. Queue's one bulk
urb per USB tick (1ms).
- FIR unpack now uses get_unaligned and cpu32_le
instead of explicit shifts
- FIR unpack copies small frames
* Transmitter:
- pack data into io buffer. Since irda is half duplex
can use same buffer for transmit and receive.
- use xchange and wait_event for synchronization
* Other:
- use USB format messages rather than IRDA (ugly)
- clean up USB startup
- reset device on network open to clear up stuck state
- handle FIFO errors
- disconnect cleanup (from viro)
- don't DMA onto stack when reading fifo status
This adds a "timbase" entry in /proc/cpuinfo like p/iSeries that
provides the CPU timebase frequency. It is using by a all sort of

It also remove a useless bit about the l2 cache that was copied over
from ppc32.
I've had reports of flicker that appear with large (23") flat panels

PLL divider values fix it (like it fixes the blur problem on TMDS2).
There should not be anything special with TMDS1 and "odd" PLL values
though, so the problem may be subtly different (a bandwidth problem),
but until I have proper bandwidth calculation and access to this
monitor, the following patch is an acceptable workaround (Odd PLL values
aren't that useful anyway)
