* backlight: constify backlight_opsLionel Debroux2010-11-16
| | | | | | | | | | | | backlight_device_register has been expecting a const "ops" argument, and using it as such, since 9905a43b2d563e6f89e4c63c4278ada03f2ebb14. Let's make the remaining backlight_ops instances const. Inspired by hunks of the grsecurity patch, updated for newer kernels.

* hibernation: constify platform_hibernation_opsLionel Debroux2010-11-16
| | | | | | | | | | Patch against mainline. Changes since v1: added one hunk; no longer adding "const" qualifier to pointers in platform_hibernation_ops after seeing b4144e4f6e3b448d322095ca08af393682a69e33. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

The oprofile is initialised using system timer in absence of hardware counters supports. Oprofile isn't started from userland. In this setup while doing a CPU offline the kernel hangs in infinite for loop inside lock_hrtimer_base() function This happens because as part of oprofile_cpu_notify(, it tries to stop an hrtimer which was never started. These per-cpu hrtimers are started when the oprfile is started. echo 1 > /dev/oprofile/enable This problem also existwhen the cpu is booted with maxcpus parameter set. When bringing the remaining cpus online the timers are started even if oprofile is not yet enabled. This patch fix this issue by adding a state variable so that these hrtimer start/stop is only attempted when oprofile is started For stable kernels v2.6.35.y and v2.6.36.y.

Solve this by acquiring a reference to the task struct under rcu_read_lock and call tty_audit_push_task outside of the preempt disabled region. Move all code which needs to be protected by sighand lock into tty_audit_push_task() and use lock/unlock_sighand as we do not hold tasklist_lock.

You still need to ensure that block devices of that module aren't mounted. This is due to the fact that as long as a block device is open, it still exists, therefore if we were to allow module removal, this block device might became used again. This time in addition to code review, I also made the code pass some torture tests like module reload in a loop + read in a loop + card insert/removal all at same time. The blktrans_open/blktrans_release don't take the mtd table lock because: While device is added (that includes execution of add_mtd_blktrans_dev) the lock is already taken Now suppose the device will never be removed. In this case even if we have changes in mtd table, the entry that we need will stay exactly the same. (Note that we don't look at table at all, just following private pointer of block device). Now suppose that someone tries to remove the mtd device. This will be propagated to trans driver which _ought_ to call del_mtd_blktrans_dev which will take the per device lock, release the mtd device and set trans->mtd = NULL. >From this point on, following opens won't even be able to know anything about that mtd device (which at that point is likely not to exist) Also the same care is taken not to trip over NULL mtd pointer in blktrans_dev_release.

This failure could be due to size = 0, which might be passed via the device-tree. This is needed for boards, where a "reg" tuple might have size 0 (of_address_to_resource() returns with EINVAL when size = 0). Example: Fully equipped board: reg = <0 0x00000000 0x00400000 0 0x00400000 0x00400000>; Partially equipped board: reg = <0 0x00000000 0x00400000 0 0x00400000 0x00000000>; This could be the case on boards with runtime detection of multiple NOR flash configurations where the detected flash size is inserted into the dtb in U-Boot.

During identification of the NAND chip this information is collected by scanning the complete chip. The option NAND_USE_FLASH_BBT is used to store this information in a sector so we don't have to scan the complete flash. Unfortunately the code stores a marker in order to recognize the BBT in the OOB area. This will fail if the OOB area is completely used for ECC. This patch introduces the option NAND_USE_FLASH_BBT_NO_OOB which has to be used with NAND_USE_FLASH_BBT. It will then store BBT on flash without touching the OOB area. The BBT format on flash remains same except the first page starts with the recognition pattern followed by the version byte. This change was tested in nandsim and it looks good so far :) Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
