2009-07-22fbmon: work around compiler bug in gcc-2.4.2Linus Torvalds
There's some odd bug in gcc-4.2 where it miscompiles a simple loop whent he loop counter is of type 'unsigned char' and it should count to 128. The compiler will incorrectly decide that a trivial loop like this: unsigned char i, ... for (i = 0; i < 128; i++) { .. is endless, and will compile it to a single instruction that just branches to itself. This was triggered by the addition of '-fno-strict-overflow', and we could play games with compiler versions and go back to '-fwrapv' instead, but the trivial way to avoid it is to just make the loop induction variable be an 'int' instead. Thanks to Krzysztof Oledzki for reporting and testing and to Troy Moure for digging through assembler differences and finding it.

2009-07-21ide: fix memory leak when flush command is issuedMaxime Bizon
I'm using ide on 2.6.30.1 with xfs filesystem. I noticed a kernel memory leak after writing lots of data, the kmalloc-96 slab cache keeps growing. It seems the struct ide_cmd kmalloced by idedisk_prepare_flush is never kfreed. Commit a09485df9cda49fbde2766c86eb18a9cae585162 ("ide: move request type specific code from ide_end_drive_cmd() to callers (v3)") and f505d49ffd25ed062e76ffd17568d3937fcd338c ("ide: fix barriers support") cause this regression, cmd->rq must now be set for ide_complete_cmd to honor the IDE_TFLAG_DYN flag.

2009-07-21NFSv4: Fix a problem whereby a buggy server can oops the kernelTrond Myklebust
We just had a case in which a buggy server occasionally returns the wrong attributes during an OPEN call. While the client does catch this sort of condition in nfs4_open_done(), and causes the nfs4_atomic_open() to return -EISDIR, the logic in nfs_atomic_lookup() is broken, since it causes a fallback to an ordinary lookup instead of just returning the error. When the buggy server then returns a regular file for the fallback lookup, the VFS allows the open, and bad things start to happen, since the open file doesn't have any associated NFSv4 state. The fix is firstly to return the EISDIR/ENOTDIR errors immediately, and secondly to ensure that we are always careful when dereferencing the nfs_open_context state pointer.

2009-07-21NFSv4: Fix an NFSv4 mount regressionTrond Myklebust
Commit 008f55d0e019943323c20a03493a2ba5672a4cc8 (nfs41: recover lease in _nfs4_lookup_root) forces the state manager to always run on mount. This is a bug in the case of NFSv4.0, which doesn't require us to send a setclientid until we want to grab file state. In any case, this is completely the wrong place to be doing state management. Moving that code into nfs4_init_session... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2009-07-21NFSv4: Fix an Oops in nfs4_free_lock_stateTrond Myklebust
The oops http://www.kerneloops.org/raw.php?rawid=537858&msgid= appears to be due to the nfs4_lock_state->ls_state field being uninitialised. This happens if the call to nfs4_free_lock_state() is triggered at the end of nfs4_get_lock_state(). The fix is to move the initialisation of ls_state into the allocator.

Many Nokia handsets support a Phonet interface to the cellular modem via a vendor-specific USB interface. CDC Phonet follows the Communications Device Class model, with one control interface, and and a pair of inactive and active data alternative interface. The later has two bulk endpoint, one per direction. This was tested against Nokia E61, Nokia N95, and the existing Phonet gadget function for the Linux composite USB gadget framework.

2009-07-21macsonic: move probe function to .devinit.textUwe Kleine-König
A pointer to mac_sonic_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. Various other functions that are called by mac_sonic_probe need to move to .devinit.text, too. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

2009-07-21genirq: Delegate irq affinity setting to the irq threadThomas Gleixner
irq_set_thread_affinity() calls set_cpus_allowed_ptr() which might sleep, but irq_set_thread_affinity() is called with desc->lock held and can be called from hard interrupt context as well. The code has another bug as it does not hold a ref on the task struct as required by set_cpus_allowed_ptr(). Just set the IRQTF_AFFINITY bit in action->thread_flags. The next time the thread runs it migrates itself. Solves all of the above problems nicely. Add kerneldoc to irq_set_thread_affinity() while at it.
