* [SCSI] sd: update sd to use the new pm callbacksAaron Lu2012-11-301-6/+13
| | | | | | | | | | | | | | | | | | | | Update sd driver to use the callbacks defined in dev_pm_ops. sd_freeze is NULL, the bus level callback has taken care of quiescing the device so there should be nothing needs to be done here. Consequently, sd_thaw is not needed here either. suspend, poweroff and runtime suspend share the same routine sd_suspend, which will sync flush and then stop the drive, this is the same as before. resume, restore and runtime resume share the same routine sd_resume, which will start the drive by putting it into active power state, this is also the same as before.

* [SCSI] scsi_pm: use callbacks from dev_pm_ops for scsi devicesAaron Lu2012-11-301-33/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | Use of pm_message_t is deprecated and device driver is not supposed to use that. This patch migrates the SCSI bus level pm callbacks to call device's pm callbacks defined in its driver's dev_pm_ops. This is achieved by finding out which device pm callback should be used in bus callback function, and then pass that callback function pointer as a param to the scsi_bus_{suspend,resume}_common routine, which will further pass that callback to scsi_dev_type_{suspend,resume} after proper handling. The special case for freeze in scsi_bus_suspend_common is not necessary since there is no high level SCSI driver has implemented freeze, so no need to runtime resume the device if it is in runtime suspended state for system freeze, just return like the system suspend/hibernate case. Since only sd has implemented drv->suspend/drv->resume, and I'll update sd driver to use the new callbacks in the following patch, there is no need to fallback to call drv->suspend/drv->resume if dev_pm_ops is NULL.

* [SCSI] sd: put to stopped power state when runtime suspendAaron Lu2012-11-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When device is runtime suspended, put it to stopped power state to save some power. This will also make the behaviour consistent with what the scsi_pm.c thinks about sd as the comment says: sd treats runtime suspend, system suspend and system hibernate identical. With this patch, it is now identical. And sd_shutdown will also do nothing when it finds the device has been runtime suspended, if we do not spin down the disk in runtime suspend by putting it into stopped power state, the disk will be shut down incorrectly. And the the same problem can be solved for runtime power off after runtime suspended case by this change. With the current runtime scheme for disk, it will only be runtime suspended when no process opens the disk, so this shouldn't happen a lot, which makes it acceptable to spin down the disk when runtime suspended. If some day a more aggressive runtime scheme is used, like the 'request based runtime pm for disk' that Alan Stern and Lin Ming has been working, we can introduce some policy to control this. But for now, make it simple and correct by spinning down the disk. Signed-off-by: Aaron Lu <aaron.lu@intel.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Rafael J.

* [SCSI] mvsas: fix undefined bit shiftXi Wang2012-11-302-13/+3
| | | | | | | | | | | | | | | | | | | | | The macro bit(n) is defined as ((u32)1 << n), and thus it doesn't work with n >= 32, such as in mvs_94xx_assign_reg_set(): if (i >= 32) { mvi->sata_reg_set |= bit(i); ... } The shift ((u32)1 << n) with n >= 32 also leads to undefined behavior. The result varies depending on the architecture. This patch changes bit(n) to do a 64-bit shift. It also simplifies mv_ffc64() using __ffs64(), since invoking ffz() with ~0 is undefined.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | store_host_reset() has tried to re-invent the wheel to compare sysfs strings.

The initial fix wasn't quite complete, so it's in two parts. In fact the first part is committed twice (Artem committed his own copy of the same patch) and I've merged Artem's tree into mine which already had that fix. I'd have recommitted that to make it somewhat cleaner, but figured by this point in the release cycle it was better to merge *exactly* the commits which have been in linux-next. If I'd recommitted, I'd also omit the sparse warning fix. But it's there, and it's harmless — just marking one function as 'static' in onenand code. This also includes a couple more fixes for stable: an AB-BA deadlock in JFFS2, and an invalid range check in slram." * tag 'for-linus-20121123' of git://git.infradead.org/mtd-2.6: mtd: nand: fix Samsung SLC detection regression mtd: nand: fix Samsung SLC NAND identification regression jffs2: Fix lock acquisition order bug in jffs2_write_begin mtd: onenand: Make flexonenand_set_boundary static mtd: slram: invalid checking of absolute end address mtd: ofpart: Fix incorrect NULL check in parse_ofoldpart_partitions() mtd: nand: fix Samsung SLC NAND identification regression

The fix is to, for now, only use the new Samsung table for MLC. We cannot support the new SLC (K9FAG08U0M) until Samsung gives better ID decode information. Note that this applies in addition to the previous regression fix: commit bc86cf7af2ebda88056538e8edff852ee627f76a mtd: nand: fix Samsung SLC NAND identification regression Together, these patches completely restore the previous detection behavior so that we cannot see any more regressions in Samsung SLC NAND (finger crossed). With luck, I can get a hold of a Samsung representative and stop having to cross my fingers eventually.

I have heuristically determined that all the chips that use the new table have ID strings which wrap around after the 6th byte. Unfortunately, I overlooked the fact that some older Samsung SLC (which use a different decoding table) have "5 byte ID strings" which also wrap around after the 6th byte. This patch re-introduces a distinction between these old and new Samsung NAND by checking that the 6th byte is non-zero, allowing both old and new Samsung NAND to be detected properly.
