Always call _pmbus_read_byte() instead of pmbus_read_byte() in PMBus core driver. With this change, device specific read functions can be implemented for all registers. Since the device specific read_byte function is now always called, we need to be more careful with page validations. Only fail if the passed page number is larger than 0, since -1 means "current page".

Before this patch the f71882fg driver completely fails to initialize on systems which have reserved settings in the pwm enable register, and it disables all auto pwm sysfs attributes if any fan is controlled by a digital sensor reading.

2011-10-24hwmon: (pmbus) Don't return errors from driver remove functionsGuenter Roeck10-21/+18
Driver remove functions have an error return value, but rarely return an error in practice. If a driver does return an error from its remove function, the driver won't be unloaded and is expected to stay alive. pmbus_do_remove() is defined as returning an int, but always returns 0 (no error). Calling code passes that return value on to high level driver remove functions, but does not evaluate it and removes driver data even if pmbus_do_remove() returned an error (which it in practice never does). Even if this code could never cause a real problem, it is nevertheless conceptually wrong. To reduce confusion and simplify the code, change pmbus_do_remove() to be a void function, and have PMBus client drivers always return zero in their driver remove functions.

2011-10-21crypto: ghash - Avoid null pointer dereference if no key is setNick Bowler1-0/+6
The ghash_update function passes a pointer to gf128mul_4k_lle which will be NULL if ghash_setkey is not called or if the most recent call to ghash_setkey failed to allocate memory. This causes an oops. Fix this up by returning an error code in the null case. This is trivially triggered from unprivileged userspace through the AF_ALG interface by simply writing to the socket without setting a key. The ghash_final function has a similar issue, but triggering it requires a memory allocation failure in ghash_setkey _after_ at least one successful call to ghash_update.

I don't usually pay much attention to the stale "?

The danger is that move_ptes() lets a migration entry dodge around behind remove_migration_pte()'s back, so it's in the old location when looking at the new, then in the new location when looking at the old. Either mremap's move_ptes() must additionally take anon_vma lock(), or migration's remove_migration_pte() must stop peeking for is_swap_entry() before it takes pagetable lock. Consensus chooses the latter: we prefer to add overhead to migration than to mremapping, which gets used by JVMs and by exec stack setup.

2011-10-19r8169: fix driver shutdown WoL regression.françois romieu1-32/+56
Due to commit 92fc43b4159b518f5baae57301f26d770b0834c9 ("r8169: modify the flow of the hw reset."), rtl8169_hw_reset stomps during driver shutdown on RxConfig bits which are needed for WOL on some versions of the hardware. As these bits were formerly set from the r81{0x, 68}_pll_power_down methods, factor them out for use in the driver shutdown (rtl_shutdown) handler. I favored __rtl8169_get_wol() -hardware state indication- over RTL_FEATURE_WOL as the latter has become a good candidate for removal.

2011-10-19[media] videodev: fix a NULL pointer dereference in v4l2_device_release()Antonio Ospite1-1/+1
The change in 8280b66 does not cover the case when v4l2_dev is already NULL, fix that. With a Kinect sensor, seen as an USB camera using GSPCA in this context, a NULL pointer dereference BUG can be triggered by just unplugging the device after the camera driver has been loaded.

2011-10-19intel-iommu: fix superpage support in pfn_to_dma_pte()Allen Kay1-9/+8
If target_level == 0, current code breaks out of the while-loop if SUPERPAGE bit is set. We should also break out if PTE is not present. If we don't do this, KVM calls to iommu_iova_to_phys() will cause pfn_to_dma_pte() to create mapping for 4KiB pages.

set dmar->iommu_superpage field to the smallest common denominator of super page sizes supported by all active VT-d engines. Initialize this field in intel_iommu_domain_init() API so intel_iommu_map() API will be able to use iommu_superpage field to determine the appropriate super page size to use.
