2008-01-26[ARM] 4711/1: pxa: mmc: move DMA specific code to platform layerBridge Wu2-7/+33
This patch is to move pxamci DMA specific code to corresponding platform layer because using DRCMRRXMMC/DRCMRTXMMC in pxamci.c makes the driver code dedicated to platform which is not extensible. It is applicable to all pxa platforms. Signed-off-by: Bridge Wu <bridge.wu@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] 4709/1: pxa: mmc: add 26MHz support for pxa3[0|1]0 mmc controllerBridge Wu1-9/+22
pxa3[0|1]0 mmc controller can support 26MHz clock mode, they support SD spec 1.1 and MMC spec 4.0 which specify high speed mode. So host caps will include MMC_CAP_MMC_HIGHSPEED and MMC_CAP_SD_HIGHSPEED for pxa3[0|1]0. This patch is to add 26MHz support for them. pxa host clock will be set to 26MHz mode when the card supported max clock rate is higher than or equal to 26MHz.

2008-01-26[ARM] pxa: make pxa2xx_spi driver use ssp_request()/ssp_free()eric miao4-127/+53
1. make pxa2xx_spi.c use ssp_request() and ssp_free() to get the common information of the designated SSP port. 2. remove those IRQ/memory request code, ssp_request() has done that for the driver 3. the SPI platform device is thus made psuedo, no resource (memory/IRQ) has to be defined, all will be retreived by ssp_request() 4. introduce ssp_get_clk_div() to handle controller difference in clock divisor setting 5. use clk_xxx() API for clock enable/disable, and clk_get_rate() to handle the different SSP clock frequency between different processors Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-01-26ocfs2: clean up bh null checksMark Fasheh2-15/+8

2008-01-26ocfs2/dlm: Clear joining_node on hearbeat node downTao Ma1-6/+6
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>

2008-01-26[PATCH 1/2] ocfs2: add flock lock typeMark Fasheh5-0/+284
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.

2008-01-26ocfs2: Local alloc window size changeable via mount optionSunil Mushran6-14/+62
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>

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.

2008-01-26[PATCH 2/2] ocfs2: Implement group add for online resizeTao Ma5-1/+269
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.

2008-01-26[PATCH 1/2] ocfs2: Add group extend for online resizeTao Ma10-7/+518
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.

2008-01-26ocfs2: Initalize bitmap_cpg of ocfs2_super to be the maximum.Tao Ma1-18/+1
This value is initialized from global_bitmap->id2.i_chain.cl_cpg. If there is only 1 group, it will be equal to the total clusters in the volume. So as for online resize, it should change for all the nodes in the cluster. It isn't easy and there is no corresponding lock for it. bitmap_cpg is only used in 2 areas: 1. Check whether the suballoc is too large for us to allocate from the global bitmap, so it is little used. And now the suballoc size is 2048, it rarely meet this situation and the check is almost useless. 2. Calculate which group a cluster belongs to. We use it during truncate to figure out which cluster group an extent belongs too. But we should be OK if we increase it though as the cluster group calculated shouldn't change and we only ever have a small bitmap_cpg on file systems with a single cluster group.

Currently it is possible to select HW_RANDOM as a module and have hifn795x built-in. This causes a build problem because hifn795x will then call hwrng_register which isn't built-in.
