ATA_FLAG_IRQ_MASK was added when I did the original data transfer with
IRQ masked bits for PIO. It has since been replaced by ->pio_data_xfer
methods so should be removed so nobody uses it by mistake thinking it
still works.

There already exists a big endian safe bitops implementation in
lib/find_next_bit.c. The code in it is 90%+ common with the powerpc
specific version, so the powerpc version is redundant. This patch
makes the necessary changes to use the generic bitops in powerpc, and
removes the powerpc specific version.

First we capture all the strings from dt.c statically by noting that gcc
puts them in a special section of their own. Idea from Michael Ellerman.
Then we move the flattened device tree to klimit.
Still to come, making the values blob grow as needed.

Use the PCI class code to choose a name for the PCI device nodes and
to guess a device_type. Failing that, base the name on the vendor and
device ids as specified in the spec.
Mark just about everything __init{data}.

We need to pass the device in order to do per device checks such as
32bit I/O enables. With the changes to include dev->ap we now don't have
to add parameters however just clean them up. Also add data_xfer methods
to the existing drivers except ata_piix (which is in the other block of
patches). If you reject the piix one just add a data_xfer to it...

This patch provides a sysfs interface to change some properties of the
ibmveth buffer pools (size of the buffers, number of buffers per pool,
and whether a pool is active). Ethernet drivers use ethtool to provide
this type of functionality. However, the buffers in the ibmveth driver
can have an arbitrary size (not only regular, mini, and jumbo which are
the only sizes that ethtool can change), and also ibmveth can have an
arbitrary number of buffer pools
Under heavy load we have seen dropped packets which obviously kills TCP
performance. We have created several fixes that mitigate this issue,
but we definitely need a way of changing the number of buffers for an
adapter dynamically. Also, changing the size of the buffers allows
users to change the MTU to something big (bigger than a jumbo frame)
greatly improving performance on partition to partition transfers.
The patch creates directories pool1...pool4 in the device directory in
sysfs, each with files: num, size, and active (which default to the
values in the mainline version).
Comments and suggestions are welcome...

The truncate threshold calculation to prevent receiver from getting stuck
was incorrect, and it didn't take into account the upper limit on bits
in the register so the jumbo packet support was broken.

As the first step towards eliminating the ref->next_phys member and saving
memory by using an _array_ of struct jffs2_raw_node_ref per eraseblock,
stop the write functions from allocating their own refs; have them just
_reserve_ the appropriate number instead. Then jffs2_link_node_ref() can
just fill them in.
Use a linked list of pre-allocated refs in the superblock, for now. Once
we switch to an array, it'll just be a case of extending that array.

Bridge will OOPS on removal if other application has the SAP open.
The bridge SAP might be shared with other usages, so need
to do reference counting on module removal rather than explicit
close/delete.
Since packet might arrive after or during removal, need to clear
the receive function handle, so LLC only hands it to user (if any).

The condition "> H323_ERROR_STOP" can never be true since H323_ERROR_STOP
is positive and is the highest possible return code, while real errors are
negative, fix the checks. Also only abort on real errors in some spots
that were just interpreting any return value != 0 as error.
Fixes crashes caused by use of stale data after a parsing error occured:
