On x86-64, kernel memory freed after init can be entirely unmapped instead
of just getting 'poisoned' by overwriting with a debug pattern.
On i386 and x86-64 (under CONFIG_DEBUG_RODATA), kernel text and bug table
can also be write-protected.

The parity calculation for an expansion operation is the same as the
calculation performed at the end of a write with the caveat that all blocks
in the stripe are scheduled to be written. An expansion operation is
identified as a stripe with the POSTXOR flag set and the BIODRAIN flag not
set.
handle_stripe sets STRIPE_OP_CHECK to request a check operation in
raid5_run_ops. If raid5_run_ops is able to perform the check with a
dma engine the parity will be preserved in memory removing the need to
re-read it from disk, as is necessary in the synchronous case.
'Repair' operations re-use
handle_stripe sets STRIPE_OP_COMPUTE_BLK to request servicing from
raid5_run_ops. It also sets a flag for the block being computed to let
other parts of handle_stripe submit dependent operations. raid5_run_ops
guarantees that the compute operation completes before any dependent
operation starts.
handle_stripe sets STRIPE_OP_PREXOR, STRIPE_OP_BIODRAIN, STRIPE_OP_POSTXOR
to request a write to the stripe cache. raid5_run_ops is triggerred to run
and executes the request outside the stripe lock.
Changelog:
* make the 'rcw' parameter to handle_write_operations5 a simple flag, Neil

Each stripe has three flag variables to reflect the state of operations
(pending, ack, and complete).

-complete: set when the operation is complete and it is ok for handle_stripe5
to
Prepare the raid5 implementation to use async_tx for running stripe
operations:
* biofill (copy data into request buffers to satisfy a read request)
* compute block (generate a missing block in the cache from the other
blocks)
* prexor (subtract existing data as part of the read-modify-write
The async_tx api provides methods for describing a chain of asynchronous
bulk memory transfers/transforms with support for inter-transactional
dependencies. It is implemented as a dmaengine client that smooths over
the details of different hardware offload engine implementations. Code
that is

This effectively makes channels a shared resource rather than tying them
to a specific client. dmaengine now assumes that clients will internally
track how many channels they need and dmaengine will learn if the client cares
about
a channel at dma_event_callback time. This also enables a client

In preparation for the async_tx (dmaengine client) API this patch:
1/ introduces struct dma_async_tx_descriptor as a common field for all
dmaengine software descriptors. The primary role of this structure
is to enable callbacks at transaction completion time, and support
transaction
I am pleased to release this latest spin of the raid acceleration
patches for merge consideration. This release aims to address all
pending review items including MD bug fixes and async_tx api changes
from Neil, and concerns on channel management from Chris and others.
