2008-01-28[ARM] 4737/1: Refactor corgi_lcd to improve readability + bugfixRichard Purdie
This patch refactors the code in corgi_lcd.c moving it to the board specific corgi and spitz files where appropriate instead of the existing ifdef mess which hinders readability. Fix spitz_get_hsync_len() to call get_hsync_invperiod so pxafb can be compiled as a module. The confusing variables which represent the inverse horizintal sync period are renamed to "invperiod" consistently. An incorrect comment in corgi_ts.c is also corrected.

This patch adds baseboard support for the phyCORE-PXA270 development kit (aka PCM-990). This example shows how to use some phyCORE-PXA270 CPU module features on a baseboard in a standard manner. It could be used as a starting point for custom baseboard development. V2: After comments by Eric Miao: - IRQ chained handler fixed - video/graphic support moved to separate patch - ifdef/endif hell reduced ;-) V3: After comments by Russell King - initialise the mmci platform data statically V4: After comments by Russell King - wrong return value in pcm990_mci_init() fixed Signed-off-by: Juergen Beisert <j.beisert@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-28[ARM] 4744/1: pcm027: add support for phyCORE-PXA270 CPU moduleRobert Schwebel
This patch adds main support for the generic phyCORE-PXA270 CPU module (aka PCM-027). Its as generic as possible to support any kind of baseboard. Note: Neither the CPU module nor the pcm027.c implementation can work without a baseboard support. Baseboard support can be added by the PCM-990 or any custom variant. V2: After comments by Eric Miao: - Currently unsupported devices moved into separate patch - direct call of baseboard initialisation V3: After comments by Russell King - sort include files - setting RTC bit for power control removed - style problems fixed (discovered by checkpatch.pl) Signed-off-by: Juergen Beisert <j.beisert@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-01-28SG: work with the SCSI fixed maximum allocations.James Bottomley
SCSI sg table allocation has a maximum size (of SCSI_MAX_SG_SEGMENTS, currently 128) and this will cause a BUG_ON() in SCSI if something tries an allocation over it. This patch adds a size limit to the chaining allocator to allow the specification of the maximum allocation size for chaining, so we always chain in units of the maximum SCSI allocation size.

2008-01-28kernel: add CLONE_IO to specifically request sharing of IO contextsJens Axboe
syslets (or other threads/processes that want io context sharing) can set this to enforce sharing of io context. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-01-28block: cfq: make the io contect sharing locklessJens Axboe
The io context sharing introduced a per-ioc spinlock, that would protect the cfq io context lookup. That is a regression from the original, since we never needed any locking there because the ioc/cic were process private. The cic lookup is changed from an rbtree construct to a radix tree, which we can then use RCU to make the reader side lockless. That is the performance critical path, modifying the radix tree is only done on process creation (when that process first does IO, actually) and on process exit (if that process has done IO). As it so happens, radix trees are also much faster for this type of lookup where the key is a pointer. It's a very sparse tree. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-01-28io context sharing: preliminary supportJens Axboe
Detach task state from ioc, instead keep track of how many processes are accessing the ioc. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

This is where it belongs and then it doesn't take up space for a process that doesn't do IO. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-01-28SG: Convert SCSI to use scatterlist helpers for sg chainingJens Axboe
Also change scsi_alloc_sgtable() to just return 0/failure, since it maps to the command passed in. ->request_buffer is now no longer needed, once drivers are adapted to use scsi_sglist() it can be killed. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-01-28SG: Move functions to lib/scatterlist.c and add sg chaining allocator helpersJens Axboe

2008-01-27i2c: Add i2c_new_dummy() utilityDavid Brownell

2008-01-27i2c: Stop using the redundant client listDavid Brownell
The i2c_adapter.clients list of i2c_client nodes duplicates driver model state. This patch starts removing that list, letting us remove most existing users of those i2c-core lists. * The core I2C code now iterates over the driver model's list instead of the i2c-internal one in some places where it's safe: - Passing a command/ioctl to each client, a mechanims used almost exclusively by DVB adapters; - Device address checking, in both i2c-core and i2c-dev. * Provide i2c_verify_client() to use with driver model iterators. * Flag the relevant i2c_adapter and i2c_client fields as deprecated, to help prevent new users from appearing. For the moment the list needs to stick around, since some issues show up when deleting devices created by legacy I2C drivers. (They don't follow standard driver model rules. Removing those devices can cause self-deadlocks.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>

i2c_driver.list is superfluous, this list duplicates the one maintained by the driver core. Drop it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: David Brownell <dbrownell@users.sourceforge.net>
2008-01-27i2c: Drop redundant i2c_adapter.listJean Delvare
i2c_adapter.list is superfluous, this list duplicates the one maintained by the driver core. Drop it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: David Brownell <dbrownell@users.sourceforge.net>
2008-01-27i2c: Change prototypes of refcounting functionsJean Delvare
Use more standard prototypes for i2c_use_client() and i2c_release_client(). The former now returns a pointer to the client, and the latter no longer returns anything. This matches what all other subsystems do. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: David Brownell <david-b@pacbell.net>
2008-01-27i2c: Use the driver model reference countingJean Delvare
Don't implement our own reference counting mechanism for i2c clients when the driver model already has one. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: David Brownell <david-b@pacbell.net>
2008-01-27i2c: Constify client address dataMark M. Hoffman
This patch allows much of the I2C client address data to move from initdata into text. Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-01-27i2c: some overdue driver removalAdrian Bunk
This patch contains the overdue removal of three I2C drivers. [JD: In fact only i2c-ixp4xx can be removed at the moment, the other two platforms don't implement the generic GPIO layer yet.] Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-01-27i2c: the scheduled I2C RTC driver removalAdrian Bunk
This patch contains the scheduled removal of legacy I2C RTC drivers with replacement drivers. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
