2009-12-15nfsd: allow exports of symlinksJ. Bruce Fields
We want to allow exports of symlinks, to allow mountd to communicate to the kernel which symlinks lead to exports, and hence which symlinks need to be visible on the pseudofilesystem. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
2009-12-15nfsd: filter readdir results in V4ROOT caseJ. Bruce Fields
As with lookup, we treat every boject as a mountpoint and pretend it doesn't exist if it isn't exported. The preexisting code here is confusing, but I haven't yet figured out how to make it clearer. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

2009-12-15nfsd4: don't continue "under" mounts in V4ROOT caseJ. Bruce Fields
If /A/mount/point/ has filesystem "B" mounted on top of it, and if "A" is exported, but not "B", then the nfs server has always returned to the client a filehandle for the mountpoint, instead of for the root of "B", allowing the client to see the subtree of "A" that would otherwise be hidden by B. Disable this behavior in the case of V4ROOT exports; we implement the path restrictions of V4ROOT exports by treating *every* directory as if it were a mountpoint, and allowing traversal *only* if the new directory is exported.

2009-12-15nfsd: introduce export flag for v4 pseudorootSteve Dickson
NFSv4 differs from v2 and v3 in that it presents a single unified filesystem tree, whereas v2 and v3 exported multiple filesystem (whose roots could be found using a separate mount protocol). Our original NFSv4 server implementation asked the administrator to designate a single filesystem as the NFSv4 root, then to mount filesystems they wished to export underneath. (Often using bind mounts of already-existing filesystems.) This was conceptually simple, and allowed easy implementation, but created a serious obstacle to upgrading between v2/v3: since the paths to v4 filesystems were different, administrators would have to adjust all the paths in client-side mount commands when switching to v4. Various workarounds are possible. For example, the administrator could export "/" and designate it as the v4 root. However, the security risks of that approach are obvious, and in any case we shouldn't be requiring the administrator to take extra steps to fix this problem; instead, the server should present consistent paths across different versions by default. These patches take a modified version of that approach: we provide a new export option which exports only a subset of a filesystem. With this flag, it becomes safe for mountd to export "/" by default, with no need for additional configuration. We begin just by defining the new flag.

2009-12-15lis3: scale output values to mgSamu Onkalo
Report output values as 1/1000 of earth gravity. Output values from lis3 can be read from sysfs position entry and from input device. Input device can be accessed as event device and as joystick device. Joystick device can be in two modes. Meaning of the output values varies from case to case depending on the chip type and configuration (scale). Only joystick interface in JS_CORR_BROKEN mode returned somehow similar output values in different configurations. Joystick device is in that state by default in case of lis3. Position sysfs entry, input event device and raw joystick device have been little bit broken since meaning of the output values has been varied between 12 and 8 bit devices. Applications which relayed on those methods failed if the chip is different than the expected one. This patch converts output values to mean similar thing in different configurations. Both 8 and 12 bit devices reports now same acceleration values. If somebody implements full scale support to the driver, output values will still mean the same. Scaling factor and input device range must be updated in that case. Joystick interface in JS_CORR_BROKEN mode is not touched by this patch. All other interfaces have different scale after this change. For 12 bit device scaling factor is 0.977 which keeps scaled and unscaled values are quite close to each others. For 8 bit device, scaled values are 18 times bigger than unscaled values.

2009-12-15lis3: selftest supportSamu Onkalo
Implement selftest feature as specified by chip manufacturer. Control: read selftest sysfs entry Response: "OK x y z" or "FAIL x y z" where x, y, and z are difference between selftest mode and normal mode. Test is passed when values are within acceptance limit values. Acceptance limits are provided via platform data. See chip spesifications for acceptance limits. If limits are not properly set, OK / FAIL decision is meaningless. However, userspace application can still make decision based on the numeric x, y, z values. Selftest is meant for HW diagnostic purposes. It is not meant to be called during normal use of the chip. It may cause false interrupt events. Selftest mode delays polling of the normal results but it doesn't cause wrong values. Chip must be in static state during selftest. Any acceration during the test causes most probably failure.

This new revision of the IP adds some improvements to the MCI already present in several Atmel SOC. Some new registers are added and a particular way of handling DMA interaction lead to a new sequence in function call which is backward compatible: On MCI2, we must set the DMAEN bit to enable the DMA handshaking interface. This must happen before the data transfer command is sent. A new function is able to differentiate MCI2 code and is based on knowledge of processor id (cpu_is_xxx()).

2009-12-15mmc: add module parameter to set whether cards are assumed removableBen Hutchings
Some people run general-purpose distribution kernels on netbooks with a card that is physically non-removable or logically non-removable (e.g. used for /home) and cannot be cleanly unmounted during suspend. Add a module parameter to set whether cards are assumed removable or non-removable, with the default set by CONFIG_MMC_UNSAFE_RESUME. In general, it is not possible to tell whether a card present in an MMC slot after resume is the same that was there before suspend. So there are two possible behaviours, each of which will cause data loss in some cases: CONFIG_MMC_UNSAFE_RESUME=n (default): Cards are assumed to be removed during suspend. Any filesystem on them must be unmounted before suspend; otherwise, buffered writes will be lost. CONFIG_MMC_UNSAFE_RESUME=y: Cards are assumed to remain present during suspend. They must not be swapped during suspend; otherwise, buffered writes will be flushed to the wrong card. Currently the choice is made at compile time and this allows that to be overridden at module load time.

2009-12-15sdhci: add support for the SysKonnect CardBus2SDIO adapterNicolas Pitre
This is still in use especially to develop SDIO device drivers on laptop machines which are lacking SDIO slots. This adapter supports SDIO cards only due to lack of 136-bit response capability.
