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 <ben-linux@fluff.org>

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 <ben-linux@fluff.org>

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.

-
David Howells authored
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 e7b0a61b 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.

The x86_64 call_rwsem_wait() treats the active state counter part of the R/W semaphore state as being 16-bit when it's actually 32-bit (it's half of the 64-bit state).

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 <khali@linux-fr.org> Acked-by: Michael Lawnick <ml.lawnick@gmx.de>

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.

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 <w.sang@pengutronix.de> Signed-off-by: Jean Delvare <khali@linux-fr.org>

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 <sage@newdream.net>
