2008-01-27[ARM] 4615/4: sam926[13]ek buttons updatedDavid Brownell
From: Nicolas Ferre <nicolas.ferre@rfo.atmel.com> On the at92sam9263ek board, tell the input subsystem about the buttons. This patch is taken from Andrew Victor's at91 patchset, then updated to match the latest kernel code and to use labels printed on the board. Also update the at91sam9261ek buttons to cope with input changes.

Currently the udc pullup is enabled by default on boot. If the device is connected to a host at this time, the host starts the negotiation before the udc/gadget driver is ready to handle it.

Add NEW_LEDs support for the following boards: - Cogent CSB337 - Atmel AT91RM9200-DK - Atmel AT91RM9200-EK - Atmel AT91SAM9263-EK Mostly based on patch from David Brownell. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] 4760/1: [AT91] SPI CS0 errata on AT91RM9200Andrew Victor
Due to errata regarding the handling of SPI CS0 on the AT91RM9200, the atmel_spi driver drives CS0 from the SPI controller and not as a GPIO pin. We therefore need to configure CS0 for use by the controller Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-01-26[ARM] 4757/1: [AT91] UART initializationAndrew Victor
Modify the UART initialization to allow the board-initialization code to specify which pins are connected, and which pins should therefore be initialized. The current at91_init_serial() will continue to work as-is, but is marked as "deprecated" and will be removed once the board-specific files has been updated to use the new interface. As in the AVR32 code, we assume that the TX and RX pins will always be initialized. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

On the at92sam9263ek board, tell the MACB driver the IRQ used by its PHY. This patch is taken from Andrew Victor's 2.6.23-at91 patchset; it matches board schematics.

This makes HZ configurable on AT91, following the model used on OMAP. It defaults to a power of two on AT91rm9200 chips, avoiding rounding errors which come from dividing a 32 KiHz clock to generate scheduler irqs; and uses 100 on AT91sam926x chips, using MCK/16 (multi-MHZ).

2008-01-25ocfs2: clean up bh null checksMark Fasheh

2008-01-25ocfs2/dlm: Clear joining_node on hearbeat node downTao Ma
Currently the process of dlm join contains 2 steps: query join and assert join. After query join, the joined node will set its joining_node. So if the joining node happens to panic before the 2nd step, the joined node will fail to clear its joining_node flag because that node isn't in the domain map. It at least cause 2 problems. 1. All the new join request will fail. So no new node can mount the volume. 2. The joined node can't umount the volume since during the umount process it has to wait for the joining_node to be unknown. So the umount will be hanged. The solution is to clear the joining_node before we check the domain map. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2008-01-25[PATCH 2/2] ocfs2: cluster aware flock()Mark Fasheh
Hook up ocfs2_flock(), using the new flock lock type in dlmglue.c. A new mount option, "localflocks" is added so that users can revert to old functionality as need be. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2008-01-25[PATCH 1/2] ocfs2: add flock lock typeMark Fasheh
This adds a new dlmglue lock type which is intended to back flock() requests. Since these locks are driven from userspace, usage rules are much more liberal than the typical Ocfs2 internal cluster lock. As a result, we can't make use of most dlmglue features - lock caching and lock level optimizations in particular. Additionally, userspace is free to deadlock itself, so we have to deal with that in the same way as the rest of the kernel - by allowing a signal to abort a lock request. In order to keep ocfs2_cluster_lock() complexity down, ocfs2_file_lock() does it's own dlm coordination. We still use the same helper functions though, so duplicated code is kept to a minimum.

2008-01-25ocfs2: Local alloc window size changeable via mount optionSunil Mushran
Local alloc is a performance optimization in ocfs2 in which a node takes a window of bits from the global bitmap and then uses that for all small local allocations. This window size is fixed to 8MB currently. This patch allows users to specify the window size in MB including disabling it by passing in 0. If the number specified is too large, the fs will use the default value of 8MB. mount -o localalloc=X /dev/sdX /mntpoint Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2008-01-25ocfs2: Support commit= mount optionMark Fasheh
Mostly taken from ext3. This allows the user to set the jbd commit interval, in seconds. The default of 5 seconds stays the same, but now users can easily increase the commit interval. Typically, this would be increased in order to benefit performance at the expense of data-safety. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2008-01-25[PATCH 2/2] ocfs2: Implement group add for online resizeTao Ma
This patch adds the ability for a userspace program to request that a properly formatted cluster group be added to the main allocation bitmap for an Ocfs2 file system. The request is made via an ioctl, OCFS2_IOC_GROUP_ADD. On a high level, this is similar to ext3, but we use a different ioctl as the structure which has to be passed through is different. During an online resize, tunefs.ocfs2 will format any new cluster groups which must be added to complete the resize, and call OCFS2_IOC_GROUP_ADD on each one. Kernel verifies that the core cluster group information is valid and then does the work of linking it into the global allocation bitmap.

2008-01-25[PATCH 1/2] ocfs2: Add group extend for online resizeTao Ma
This patch adds the ability for a userspace program to request an extend of last cluster group on an Ocfs2 file system. The request is made via ioctl, OCFS2_IOC_GROUP_EXTEND. This is derived from EXT3_IOC_GROUP_EXTEND, but is obviously Ocfs2 specific. tunefs.ocfs2 would call this for an online-resize operation if the last cluster group isn't full.

2008-01-25[SCSI] usbstorage: use last_sector_bug flag universallyHans de Goede
This patch sets the last_sector_bug flag to 1 for all USB disks. This is needed to makes the cardreader on various HP multifunction printers work. Since the performance impact is negible we set this flag for all USB disks to avoid an unusual_devs.h nightmare.

2008-01-25ocfs2: Reserve ioctl rangeTao Ma
We need to reserve at least two ioctls for online-resize. Reserve a small range of ioctls for Ocfs2 use in Documentation/ioctl-number.txt. This should give us enough room for future growth. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
