2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang75-141/+4
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

2010-06-03i2c: Check for address validity on client registrationJean Delvare1-7/+26
Do basic address validity checks when a client is being registered. We already had checks in place for devices which are being detected, but not for devices which are simply instantiated. This is a very basic check. We don't want to do strict checking here because some devices are known to infringe the I2C address constraints (e.g. IR receivers at 7-bit address 0x7a while this value is supposedly reserved for 10-bit addresses.) So we assume the caller knows what it is doing. Signed-off-by: Jean Delvare <[email protected]> Cc: Matthieu Castet <[email protected]>

2010-06-03xen: avoid allocation causing potential swap activity on the resume pathIan Campbell1-1/+1
Since the device we are resuming could be the device containing the swap device we should ensure that the allocation cannot cause IO. On resume, this path is triggered when the running system tries to continue using its devices. If it cannot then the resume will fail; to try to avoid this we let it dip into the emergency pools. The majority of these changes were made when linux-2.6.18-xen.hg changeset e8b49cfbdac0 was ported upstream in a144ff09bc52ef3f3684ed23eadc9c7c0e57b3aa but somehow this hunk was dropped.

2010-06-03xen: ensure timer tick is resumed even on CPU driving the resumeIan Campbell1-2/+2
The core suspend/resume code is run from stop_machine on CPU0 but parts of the suspend/resume machinery (including xen_arch_resume) are run on whichever CPU happened to schedule the xenwatch kernel thread. As part of the non-core resume code xen_arch_resume is called in order to restart the timer tick on non-boot processors. The boot processor itself is taken care of by core timekeeping code. xen_arch_resume uses smp_call_function which does not call the given function on the current processor. This means that we can end up with one CPU not receiving timer ticks if the xenwatch thread happened to be scheduled on CPU > 0. Use on_each_cpu instead of smp_call_function to ensure the timer tick is resumed everywhere.

2010-06-02libata: implement on-demand HPA unlockingTejun Heo3-0/+32
Implement ata_scsi_unlock_native_capacity() which will be called through SCSI layer when block layer notices that partitions on a device extend beyond the end of the device. It requests EH to unlock HPA, waits for completion and returns the current device capacity. This allows libata to unlock HPA on demand instead of having to decide whether to unlock upfront. Unlocking on demand is safer than unlocking by upfront because some BIOSes write private data to the area beyond HPA limit. This was suggested by Ben Hutchings.

2010-06-02sata_nv: don't diddle with nIEN on mcp55Tejun Heo1-2/+0
On mcp55, nIEN gets stuck once set and liteon blueray rom iHOS104-08 violates ATA specification and fails to set I on D2H Reg FIS if nIEN is set when the command was issued. When the other party is following the spec, both devices can work fine but when the two flaws are put together, they can't talk to each other. mcp55 has its own IRQ masking mechanism and there's no reason to mess with nIEN in the first place. Fix it by dropping nIEN diddling from nv_mcp55_freeze/thaw(). This was originally reported by Cengiz. Although Cengiz hasn't verified the fix yet, I could reproduce this problem and verfiy the fix. Even if Cengiz is experiencing different or additional problems, this patch is needed.
