This patch adds a new versatile platform for when using the device

irq_domain_generate_simple() is an easy way to generate an irq translation
domain for simple irq controllers. It assumes a flat 1:1 mapping from
hardware irq number to an offset of the first linux irq number assigned
to the controller
Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
This patch adds irq_domain infrastructure for translating from
hardware irq numbers to linux irqs. This is particularly important
for architectures adding device tree support because the current
implementation (excluding PowerPC and SPARC) cannot handle
translation for more than a single interrupt controller. irq_domain
supports device tree translation for any number of interrupt
controllers.
This patch converts x86, Microblaze, ARM and MIPS to use irq_domain
for device tree irq translation. x86 is untested beyond compiling it,
irq_domain is enabled for MIPS and Microblaze, but the old behaviour is
preserved until the core code is modified to actually register an
irq_domain yet. On ARM it works and is required for much of the new
ARM device tree board support.
PowerPC has /not/ been converted to use this new infrastructure. It
is still missing some features before it can replace the virq
infrastructure already in powerpc (see documentation on
irq_domain_map/unmap for details). Followup patches will add the
missing pieces and migrate PowerPC to use irq_domain.
SPARC has its own method of managing interrupts from the device tree
and is unaffected by this change.

I noticed that you took some time back in late 2009 to 'consolidate' the
split format-strings present in the bonding driver at the time and I've
decided I'm fine to leave them the way they are. The main point of my
patch was to change the output and I would like to get that included.
Here is my updated patch...
Subject: [PATCH net-next-2.6 v2] bonding: reduce noise during init
Many are using sysfs to configure bonding rather than module options, so
there is no need for bonding to throw this warning in normal cases.
Keep the message around when debugging is enabled as it might be useful
for someone desperate enough to enable debugging, but eliminate it
otherwise.

When a bond contains a device where one name is the subset of another
(eth1 and eth10, for example), one cannot properly set the primary
device or the currently active device.
This was reported and based on work by Takuma Umeya. I also verified
the problem and tested that this fix resolves it.
V2: A few did not like the the current code or my changes, so I
refactored bonding_store_primary and bonding_store_active_slave to be a
bit cleaner, dropped the use of strnicmp since we did not really need
the comparison to be case insensitive, and formatted the input string
from sysfs so a comparison to IFNAMSIZ could be used.
I also discovered an error in bonding_store_active_slave that would
modify bond->primary_slave rather than bond->curr_active_slave before
forcing the bonding driver to choose a new active slave.
V3: Actually sending the proper patch....

Pktgen attempts to transmit shared skbs to net devices, which can't be used by
some drivers as they keep state information in skbs. This patch adds a flag
marking drivers as being able to handle shared skbs in their tx path. Drivers
are defaulted to being unable to do so, but calling ether_setup enables this
flag, as 90% of the drivers calling ether_setup touch real hardware and can
handle shared skbs. A subsequent patch will audit drivers to ensure that the
flag is set properly

The cpu compatible string we look for is "SPARC-T3".
As far as memset/memcpy optimizations go, we treat this chip the same
as Niagara-T2/T2+. Use cache initializing stores for memset, and use
perfetch, FPU block loads, cache initializing stores, and block stores
for copies.
We use the Niagara-T2 perf support, since T3 is a close relative in
this regard. Later we'll add support for the new events T3 can
report, plus enable T3's new "sample" mode.
For now I haven't added any new ELF hwcap flags. We probably need
to add a couple, for example:
T2 and T3 both support the population count instruction in hardware.
T3 supports VIS3 instructions, including support (finally) for
partitioned shift. One can also now move directly between float
and integer registers.
T3 supports instructions meant to help with Galois Field and other HPC
calculations, such as XOR multiply. Also there are "OP and negate"
instructions, for example "fnmul" which is multiply-and-negate.
T3 recognizes the transactional memory opcodes, however since
transactional memory isn't supported: 1) 'commit' behaves as a NOP and
2) 'chkpt' always branches 3) 'rdcps' returns all zeros and 4) 'wrcps'
behaves as a NOP.
So we'll need about 3 new elf capability flags in the end to represent
all of these things.
