This patch adds support for ADMA mode on NVIDIA nForce4 (CK804/MCP04) SATA
controllers to the sata_nv driver. Benefits of ADMA mode include:
- NCQ support
- Reduced CPU overhead (controller DMAs command information from memory
instead of them being pushed in by the CPU)
- Full 64-bit DMA support
ADMA mode is enabled by default in this version. To disable it, set the
module parameter adma_enabled=0.

- use pci_iomap() [Alan, version 0.0.5t]
- fix Alan's version 0.0.5t change
- line length, trailing whitespace, case indentation cleanups
- don't use deprecated ->eng_timeout() in a driver that uses new EH

This is a legacy mode PATA driver for the 6101/45 and will also drive
the SATA ports 1 & 2 in legacy mode as well if desired. Tested and
confirmed working by users. The chip supports AHCI type behaviour for
SATA and has a more advanced PATA interface as well so this driver will
get it working but not get best performance for now.

Winbond 83759A support in non-multichip mode (afaik nobody ever used
multichip mode anyway). The 83759 is not supported by this driver as it
is already handled elsewhere and doens't use the same interfaces.

Implement .permission() in ocfs2_file_iops, ocfs2_special_file_iops and
ocfs2_dir_iops.
This helps us avoid some multi-node races with mode change and vfs
operations.

This is mostly a search and replace as ocfs2_journal_handle is now no more
than a container for a handle_t pointer.
ocfs2_commit_trans() becomes very straight forward, and we remove some out
of date comments / code.

All callers either pass in NULL directly, or a local variable that is
already set to NULL.
The internals of ocfs2_start_trans() get a nice cleanup as a result.
Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
This gets us rid of a slab we no longer need, as well as removing the
majority of what's left on ocfs2_journal_handle.
ocfs2_commit_unstarted_handle() has no more real work to do, so remove that
function too.

We can also delete the unused infrastructure which was once in place to
support this functionality. ocfs2_inode_private loses ip_handle and
ip_handle_list. ocfs2_journal_handle loses handle_list.

Instead we record our state on the allocation context structure which all
callers already know about and lifetime correctly. This means the
reservation functions don't need a handle passed in any more, and we can
also take it off the alloc context.

Callers can set h_sync directly on the handle_t, whether a transaction has
been started or not can be determined via the existence of the handle_t on
the struct ocfs2_journal_handle.
Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
No reason to use our wrapper struct in this function, so take the handle_t
directly.
Also fixes a bug where we were incorrectly setting the handle to NULL in
case of a failure from journal_restart()
