Periodically poll adapter registers to detect pci adapter failure (reads return -1). On failure, take port offline, set error indicators and wake up worker threads. Threads will take adapter offline.

2011-03-23[SCSI] ses: Avoid kernel panic when lun 0 is not mappedKrishnasamy, Somasundaram1-1/+1
During device discovery, scsi mid layer sends INQUIRY command to LUN 0. If the LUN 0 is not mapped to host, it creates a temporary scsi_device with LUN id 0 and sends REPORT_LUNS command to it. After the REPORT_LUNS succeeds, it walks through the LUN table and adds each LUN found to sysfs. At the end of REPORT_LUNS lun table scan, it will delete the temporary scsi_device of LUN 0. When scsi devices are added to sysfs, it calls add_dev function of all the registered class interfaces. If ses driver has been registered, ses_intf_add() of ses module will be called. This function calls scsi_device_enclosure() to check the inquiry data for EncServ bit. Since inquiry was not allocated for temporary LUN 0 scsi_device, it will cause NULL pointer exception. To fix the problem, sdev->inquiry is checked for NULL before reading it.

2011-03-23[SCSI] ses: show devices for enclosures with no page 7John Hughes1-2/+2
enclosure page 7 gives us the "pretty" names of the enclosure slots. Without a page 7, we can still use the enclosure code as long as we make up numeric names for the slots. Unfortunately, the current code fails to add any devices because the check for page 10 is in the wrong place if we have no page 7. Fix it so that devices show up even if the enclosure has no page 7.

This patch solves a stale pointer problem in update_cgrp_time_from_cpuctx(). The cpuctx->cgrp was not cleared on all possible event exit paths, including: close() perf_release() perf_release_kernel() list_del_event() This patch fixes list_del_event() to clear cpuctx->cgrp when there are no cgroup events left in the context.

2011-03-23sys_swapon: fix inode lockingCesar Eduardo Barros1-2/+5
A conflict between 52c50567d8ab ("mm: swap: unlock swapfile inode mutex before closing file on bad swapfiles") and 83ef99befc32 ("sys_swapon: remove did_down variable") caused a double unlock of the inode mutex (once in bad_swap: before the filp_close, once at the end just before returning). The patch which added the extra unlock cleared did_down to avoid unlocking twice, but the other patch removed the did_down variable. To fix, set inode to NULL after the first unlock, since it will be used after that point only for the final unlock. While checking this patch, I found a path which could unlock without locking, in case the same inode was added as a swapfile twice. To fix, move the setting of the inode variable further down, to just before claim_swapfile, which will lock the inode before doing anything else.

2011-03-23sh: Use struct syscore_ops instead of sysdevsRafael J. Wysocki3-99/+65
Convert the SuperH clocks framework and shared interrupt handling code to using struct syscore_ops instead of a sysdev classes and sysdevs for power managment. This reduces the code size significantly and simplifies it. The optimizations causing things not to be restored after creating a hibernation image are removed, but they might lead to undesirable effects during resume from hibernation (e.g. the clocks would be left as the boot kernel set them, which might be not the same way as the hibernated kernel had seen them before the hibernation). This also is necessary for removing sysdevs from the kernel entirely in the future. Signed-off-by: Rafael J. Wysocki <[email protected]> Signed-off-by: Paul Mundt <[email protected]>

2011-03-23mfd: Push byte swap out of WM8994 bulk I/OMark Brown1-4/+6
For bulk I/O it is both convenient and more sensible to pre-swap the data rather than doing the swap as part of the I/O operation so move the byte swaps we're currently doing into the core write function into the register based functions, giving the bulk write function a straight pass through to the chip.

2011-03-23regulator: MAX8997/8966 supportMyungJoo Ham4-1/+1250
This patch supports PMIC/Regulator part of MAX8997/MAX8966 MFD. In this initial release, selecting voltages or current-limit and switching on/off the regulators are supported. Controlling voltages for DVS with GPIOs is not implemented fully and requires more considerations: it controls multiple bucks (selection of 1, 2, and 5) at the same time with SET1~3 gpios. Thus, when DVS-GPIO is activated, we lose the ability to control the voltage of a single buck regulator independently; i.e., contolling a buck affects other two bucks. Therefore, using the conventional regulator framework directly might be problematic. However, in this driver, we try to choose a setting without such side effect of affecting other regulators and then try to choose a setting with the minimum side effect (the sum of voltage changes in other regulators). On the other hand, controlling all the three bucks simultenously based on the voltage set table may help build cpufreq and similar system more robust; i.e., all the three voltages are consistent every time without glitches during transition.

2011-03-23mfd: Reentrance and revamp ab8500 gpadc fetching interfaceDaniel Willerud2-46/+75
This revamps the interface so that AB8500 GPADCs are fetched by name. Probed GPADCs are added to a list and this list is searched for a matching GPADC. This makes it possible to have multiple AB8500 GPADC instances instead of it being a singleton, and rids the need to keep a GPADC pointer around in the core AB8500 MFD struct. Currently the match is made to the device name which is by default numbered from the device instance such as "ab8500-gpadc.0" but by using the .init_name field of the device a more intiutive naming for the GPADC blocks can be achieved if desired.
