Remove the last s3c2410_gpio_pullup() users in arch/arm/mach-s3c2410 Note, since mach-h1940.c is setting output and a pull-up, the call has vbeen chanerd to S3C_GPIO_PULL_NONE instead of S3C_GPIO_PULL_UP. Signed-off-by: Ben Dooks <[email protected]>
2010-05-06ARM: mini2440: Move to using gpiolib API and s3c_gpio functionsBen Dooks1-9/+9
Move the mach-mini2440 to using the gpiolib API for GPIOS it directly uses, and s3c_gpio calls for configuration. Signed-off-by: Ben Dooks <[email protected]>

2010-05-06ARM: S3C24XX: Remove s3c2410_gpio_setcfg()Ben Dooks2-59/+24
Remove the implementation of s3c2410_gpio_setcfg() as it should now be functionally equivalent to s3c_gpio_cfgpin(), and add a wrapper for those drivers that are still using this call. Signed-off-by: Ben Dooks <[email protected]>
2010-05-06ARM: S3C24XX: Drop s3c2410 specific s3c2410_gpio_cfgpin()Ben Dooks15-44/+55
The s3c_gpio_cfgpin() call should be functionally equivalent, so replace the s3c2410_gpio_cfgpin() calls in the s3c24xx code with s3c_gpio_cfgpin to allow moving away from a fixed GPIO number to register address mapping Signed-off-by: Ben Dooks <[email protected]>

Add the GPIO banks that are used on the S3C2443 and above to the list of available GPIOS. Currently we do not have any limit on the SoC GPIO, so these are being registered whether the SoC has them or not. It is currently up to the user not to try and use them.

2010-05-05KEYS: Fix RCU handling in key_gc_keyring()David Howells1-3/+6
key_gc_keyring() needs to either hold the RCU read lock or hold the keyring semaphore if it's going to scan the keyring's list. Given that it only needs to read the key list, and it's doing so under a spinlock, the RCU read lock is the thing to use. Furthermore, the RCU check added in e7b0a61b7929632d36cf052d9e2820ef0a9c1bfe is incorrect as holding the spinlock on key_serial_lock is not grounds for assuming a keyring's pointer list can be read safely. Instead, a simple rcu_dereference() inside of the previously mentioned RCU read lock is what we want. Reported-by: Serge E.

2010-05-04i2c-core: Use per-adapter userspace device listsJean Delvare2-16/+20
Using a single list for all userspace devices leads to a dead lock on multiplexed buses in some circumstances (mux chip instantiated from userspace). This is solved by using a separate list for each bus segment. Signed-off-by: Jean Delvare <[email protected]> Acked-by: Michael Lawnick <[email protected]>
2010-05-04i2c: Fix probing of FSC hardware monitoring chipsJean Delvare1-5/+16
Some FSC hardware monitoring chips (Syleus at least) doesn't like quick writes we typically use to probe for I2C chips. Use a regular byte read instead for the address they live at (0x73). These are the only known chips living at this address on PC systems. For clarity, this fix should not be needed for kernels 2.6.30 and later, as we started instantiating the hwmon devices explicitly based on DMI data. Still, this fix is valuable in the following two cases: * Support for recent FSC chips on older kernels. The DMI-based device instantiation is more difficult to backport than the device support itself. * Case where the DMI-based device instantiation fails, whatever the reason. We fall back to probing in that case, so it should work.

2010-05-04i2c-core: Erase pointer to clientdata on removalWolfram Sang2-2/+11
After discovering that a lot of i2c-drivers leave the pointer to their clientdata dangling, it was decided to let the core handle this issue. It is assumed that the core may access the private data after remove() as there are no guarantees for the lifetime of such pointers anyhow (see thread starting at http://lkml.org/lkml/2010/3/21/68) Signed-off-by: Wolfram Sang <[email protected]> Signed-off-by: Jean Delvare <[email protected]>

2010-05-03ceph: remove bad auth_x kmem_cacheSage Weil1-22/+10

2010-05-03ceph: clear dir complete, invalidate dentry on replayed renameSage Weil1-0/+9
If a rename operation is resent to the MDS following an MDS restart, the client does not get a full reply (containing the resulting metadata) back. In that case, a ceph_rename() needs to compensate by doing anything useful that fill_inode() would have, like d_move(). It also needs to invalidate the dentry (to workaround the vfs_rename_dir() bug) and clear the dir complete flag, just like fill_trace(). Signed-off-by: Sage Weil <[email protected]>
