2012-02-23hwmon: (f75375s) Fix register write order when setting fans to full speedNikolaus Schulz1-4/+3
By hwmon sysfs interface convention, setting pwm_enable to zero sets a fan to full speed. In the f75375s driver, this need be done by enabling manual fan control, plus duty mode for the F875387 chip, and then setting the maximum duty cycle. Fix a bug where the two necessary register writes were swapped, effectively discarding the setting to full-speed.

2012-02-21asm-generic: architecture independent readq/writeq for 32bit environmentHitoshi Mitake5-60/+10
This provides unified readq()/writeq() helper functions for 32-bit drivers. For some cases, readq/writeq without atomicity is harmful, and order of io access has to be specified explicitly. So in this patch, new two header files which contain non-atomic readq/writeq are added. - <asm-generic/io-64-nonatomic-lo-hi.h> provides non-atomic readq/ writeq with the order of lower address -> higher address - <asm-generic/io-64-nonatomic-hi-lo.h> provides non-atomic readq/ writeq with reversed order This allows us to remove some readq()s that were added drivers when the default non-atomic ones were removed in commit dbee8a0affd5 ("x86: remove 32-bit versions of readq()/writeq()") The drivers which need readq/writeq but can do with the non-atomic ones must add the line: #include <asm-generic/io-64-nonatomic-lo-hi.h> /* or hi-lo.h */ But this will be nop in 64-bit environments, and no other #ifdefs are required. So I believe that this patch can solve the problem of 1. driver-specific readq/writeq 2. atomicity and order of io access This patch is tested with building allyesconfig and allmodconfig as ARCH=x86 and ARCH=i386 on top of tip/master.

2012-02-21usb-storage: fix freezing of the scanning threadAlan Stern2-62/+35
This patch (as1521b) fixes the interaction between usb-storage's scanning thread and the freezer. The current implementation has a race: If the device is unplugged shortly after being plugged in and just as a system sleep begins, the scanning thread may get frozen before the khubd task. Khubd won't be able to freeze until the disconnect processing is complete, and the disconnect processing can't proceed until the scanning thread finishes, so the sleep transition will fail. The implementation in the 3.2 kernel suffers from an additional problem. There the scanning thread calls set_freezable_with_signal(), and the signals sent by the freezer will mess up the thread's I/O delays, which are all interruptible. The solution to both problems is the same: Replace the kernel thread used for scanning with a delayed-work routine on the system freezable work queue. Freezable work queues have the nice property that you can cancel a work item even while the work queue is frozen, and no signals are needed. The 3.2 version of this patch solves the problem in Bugzilla #42730.

2012-02-21xhci: Fix encoding for HS bulk/control NAK rate.Sarah Sharp1-8/+24
The xHCI 0.96 spec says that HS bulk and control endpoint NAK rate must be encoded as an exponent of two number of microframes. The endpoint descriptor has the NAK rate encoded in number of microframes. We were just copying the value from the endpoint descriptor into the endpoint context interval field, which was not correct. This lead to the VIA host rejecting the add of a bulk OUT endpoint from any USB 2.0 mass storage device. The fix is to use the correct encoding. Refactor the code to convert number of frames to an exponential number of microframes, and make sure we convert the number of microframes in HS bulk and control endpoints to an exponent. This should be back ported to kernels as old as 2.6.31, that contain the commit dfa49c4ad120a784ef1ff0717168aa79f55a483a "USB: xhci - fix math in xhci_get_endpoint_interval" Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Tested-by: Felipe Contreras <felipe.contreras@gmail.com> Suggested-by: Andiry Xu <andiry.xu@amd.com> Cc: stable@vger.kernel.org
2012-02-21USB: Set hub depth after USB3 hub resetElric Fu1-13/+17
The superspeed device attached to a USB 3.0 hub(such as VIA's) doesn't respond the address device command after resume. The root cause is the superspeed hub will miss the Hub Depth value that is used as an offset into the route string to locate the bits it uses to determine the downstream port number after reset, and all packets can't be routed to the device attached to the superspeed hub. Hub driver sends a Set Hub Depth request to the superspeed hub except for USB 3.0 root hub when the hub is initialized and doesn't send the request again after reset due to the resume process. So moving the code that sends the Set Hub Depth request to the superspeed hub from hub_configure() to hub_activate() is to cover those situations include initialization and reset. The patch should be backported to kernels as old as 2.6.39.

2012-02-21USB: Fix handoff when BIOS disables host PCI device.Sarah Sharp1-0/+11
On some systems with an Intel Panther Point xHCI host controller, the BIOS disables the xHCI PCI device during boot, and switches the xHCI ports over to EHCI. This allows the BIOS to access USB devices without having xHCI support. The downside is that the xHCI BIOS handoff mechanism will fail because memory mapped I/O is not enabled for the disabled PCI device. Jesse Barnes says this is expected behavior. The PCI core will enable BARs before quirks run, but it will leave it in an undefined state, and it may not have memory mapped I/O enabled. Make the generic USB quirk handler call pci_enable_device() to re-enable MMIO, and call pci_disable_device() once the host-specific BIOS handoff is finished. This will balance the ref counts in the PCI core. When the PCI probe function is called, usb_hcd_pci_probe() will call pci_enable_device() again. This should be back ported to kernels as old as 2.6.31. That was the first kernel with xHCI support, and no one has complained about BIOS handoffs failing due to memory mapped I/O being disabled on other hosts (EHCI, UHCI, or OHCI).

Here are a few more fixes for powerpc. Some are regressions, the rest is simple/obvious/nasty enough that I deemed it good to go now. Here's also step one of deprecating legacy iSeries support: we are removing it from the main defconfig. Nobody seems to be using it anymore and the code is nasty to maintain, (involves horrible hacks in various low level areas of the kernel) so we plan to actually rip it out at some point. For now let's just avoid building it by default. Stephen will proceed to do the actual removal later (probably 3.4 or 3.5). * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc/perf: power_pmu_start restores incorrect values, breaking frequency events powerpc/adb: Use set_current_state() powerpc: Disable interrupts early in Program Check powerpc: Remove legacy iSeries from ppc64_defconfig powerpc/fsl/pci: Fix PCIe fixup regression powerpc: Fix kernel log of oops/panic instruction dump

2012-02-18[SCSI] scsi_pm: Fix bug in the SCSI power management handlerAlan Stern2-0/+17
This patch (as1520) fixes a bug in the SCSI layer's power management implementation. LUN scanning can be carried out asynchronously in do_scan_async(), and sd uses an asynchronous thread for the time-consuming parts of disk probing in sd_probe_async(). Currently nothing coordinates these async threads with system sleep transitions; they can and do attempt to continue scanning/probing SCSI devices even after the host adapter has been suspended. As one might expect, the outcome is not ideal. This is what the "prepare" stage of system suspend was created for. After the prepare callback has been called for a host, target, or device, drivers are not allowed to register any children underneath them. Currently the SCSI prepare callback is not implemented; this patch rectifies that omission. For SCSI hosts, the prepare routine calls scsi_complete_async_scans() to wait until async scanning is finished. It might be slightly more efficient to wait only until the host in question has been scanned, but there's currently no way to do that. Besides, during a sleep transition we will ultimately have to wait until all the host scanning has finished anyway. For SCSI devices, the prepare routine calls async_synchronize_full() to wait until sd probing is finished. The routine does nothing for SCSI targets, because asynchronous target scanning is done only as part of host scanning.

2012-02-18[SCSI] scsi_scan: Fix 'Poison overwritten' warning caused by using freed 'shost'Huajun Li1-2/+2
In do_scan_async(), calling scsi_autopm_put_host(shost) may reference freed shost, and cause Posison overwitten warning. Yes, this case can happen, for example, an USB is disconnected just when do_scan_async() thread starts to run, then scsi_host_put() called in scsi_finish_async_scan() will lead to shost be freed(because the refcount of shost->shost_gendev decreases to 1 after USB disconnects), at this point, if references shost again, system will show following warning msg. To make scsi_autopm_put_host(shost) always reference a valid shost, put it just before scsi_host_put() in function scsi_finish_async_scan().

2012-02-18[SCSI] ipr: fix eeh recovery for 64-bit adaptersKleber Sacilotto de Souza1-6/+18
In some scenarios, an EEH error can take a long time to be detected, since the driver issues an MMIO read only after a device reset command times out and we try to reset the adapter. This patch adds some code in ipr_cancel_op() to read a hardware register so we detect the error earlier in case the op is being aborted because of a timeout caused by a frozen adapter slot. Another problem in such scenarios is that in __ipr_eh_host_reset() we change the dump state flag from WAIT_FOR_DUMP to GET_DUMP, and the flag is later changed from GET_DUMP to READ_DUMP in ipr_reset_restore_cfg_space(). However, if when __ipr_eh_host_reset() is called by the SCSI error handling the function ipr_reset_restore_cfg_space() has already been called by the PCI EEH code, we end up with the flag in an inconsistent state. This patch also prevents this problem.
