Use the newly introduced devm_ioremap_resource() instead of
devm_request_and_ioremap() which provides more consistent error
handling.

devm_ioremap_resource() provides its own error messages; so all explicit
error messages can be removed from the failure code paths.

In audit_data_to_entry() when a failure occurs we must check and free
the tree and watch to avoid a memory leak.

  test:
    plan:
      test command:
        "auditctl -a exit,always -w /etc -F auid=-1"
        (on fedora17, need modify auditctl to let "-w /etc" has effect)
      running:
        under fedora17 x86_64, 2 CPUs 3.20GHz, 2.5GB RAM.
        let 15 auditctl processes continue running at the same time.
      monitor command:
        watch -d -n 1 "cat /proc/meminfo | awk '{print \$2}' \
          | head -n 4 | xargs \
          | awk '{print \"used \",\$1 - \$2 - \$3 - \$4}'"

    result:
      for original version:
        will use up all memory, within 3 hours.
        kill all auditctl, the memory still does not free.
      for new version (apply this patch):

task_get_live_kthread() looks confusing and unneeded.  It does
get_task_struct() but only kthread_stop() needs this, it can be called
even if the calller doesn't have a reference when we know that this
kthread can't exit until we do kthread_stop().

kthread_park() and kthread_unpark() do not need get_task_struct(), the
callers already have the reference.  And it can not help if we can race
with the exiting kthread anyway, kthread_park() can hang forever in this
case.

Change kthread_park() and kthread_unpark() to use to_live_kthread(),
change kthread_stop() to do get_task_struct() by hand and remove
task_get_live_kthread().

"k->vfork_done != NULL" with a barrier() after to_kthread(k) in
task_get_live_kthread(k) looks unclear, and sub-optimal because we load
->vfork_done twice.

All we need is to ensure that we do not return to_kthread(NULL).  Add a
new trivial helper which loads/checks ->vfork_done once, this also looks
more understandable.

   - Patrice Chotard contributed a new configuration debugfs interface
     and reintroduced fine-grained locking into the core: instead of
     having a "big pinctrl lock" we have a per-controller lock and
     specialized locks for the global controller and pinctrl handle
     lists.

   - Haoijan Zhuang deleted all the PXA and MMP2 pinctrl drivers and
     replaced them with pinctrl-single (which is also used by other
     SoCs) so we are gaining consolidation.  The platform particulars
     now come in through the device tree.

   - Haoijan also added support for generic pin config into the
     pinctrl-single driver which is another big consolidation win.

   - Finally also GPIO ranges are now supported by the pinctrl-single
     driver.

   - Tomasz Figa contributed a new Samsung S3C pinctrl driver, bringing
     more of the older Samsung platforms under the pinctrl umbrella and
     out of arch/arm.

I think we could just move the full vm_iomap_memory() function into

using nommu even to this trivial patch, so I'm not going to touch it any
more than required.

Here's the fairly minimal stub to make the nommu case at least
potentially work.  It doesn't seem like anybody cares, though.

  aren't that many people testing the parisc linux kernel, a few (for
  our port) critical issues just showed up a few days back for the first

  What's in it?
   - add missing __ucmpdi2 symbol, which is required for btrfs on 32bit
     kernel.
   - change kunmap() macro to static inline function.  This fixes a
     debian/gcc-4.4 build error.
   - add locking when doing PTE updates.  This fixes random userspace
     crashes.
   - disable (optional) -mlong-calls compiler option for modules, else
     modules can't be loaded at runtime.
   - a smart patch by Will Deacon which fixes 64bit put_user() warnings
     on 32bit kernel."

variable_is_present() accesses '__efivars' directly, but when called via
gsmi_init() Michel reports observing the following crash,

  BUG: unable to handle kernel NULL pointer dereference at (null)
  IP: variable_is_present+0x55/0x170
  Call Trace:
    register_efivars+0x106/0x370
    gsmi_init+0x2ad/0x3da
    do_one_initcall+0x3f/0x170

The reason for the crash is that '__efivars' hasn't been initialised nor
has it been registered with register_efivars() by the time the google
EFI SMI driver runs.  The gsmi code uses its own struct efivars, and
therefore, a different variable list.  Fix the above crash by passing
the registered struct efivars to variable_is_present(), so that we
traverse the correct list.

This mutex avoids deadlock in case of use of multiple pin
controllers. Before this modification, by using a global
mutex, deadlock appeared when, for example, a call to
pinctrl_pins_show() locked the pinctrl_mutex, called the
ops->pin_dbg_show of a particular pin controller. If this
pin controller needs I2C access to retrieve configuration
information and I2C driver is using pinctrl to drive its
pins, a call to pinctrl_select_state() try to lock again
pinctrl_mutex which leads to a deadlock.

Notice that the mutex grab from the two direction functions
was moved into pinctrl_gpio_direction().

For several cases, we can't replace pinctrl_mutex by
pctldev->mutex, because at this stage, pctldev is
not accessible :
	- pinctrl_get()/pinctrl_put()
	- pinctrl_register_maps()

So add respectively pinctrl_list_mutex and
pinctrl_maps_mutex in order to protect
pinctrl_list and pinctrl_maps list instead.

Reintroduce pinctrldev_list_mutex in
find_pinctrl_by_of_node(),
pinctrl_find_and_add_gpio_range()
pinctrl_request_gpio(), pinctrl_free_gpio(),
pinctrl_gpio_direction(), pinctrl_devices_show(),
pinctrl_register() and pinctrl_unregister() to
protect pinctrldev_list.

Changes v2->v3:
- Fix a missing EXPORT_SYMBOL_GPL() for pinctrl_select_state().

Changes v1->v2:
- pinctrl_select_state_locked() is removed, all lock mechanism
  is located inside pinctrl_select_state(). When parsing
  the state->setting list, take the per-pin-controller driver
  lock. (Patrice).
- Introduce pinctrldev_list_mutex to protect pinctrldev_list
  in all functions which parse or modify pictrldev_list.
  (Patrice).
- move find_pinctrl_by_of_node() from pinctrl/devicetree.c to
  pinctrl/core.c in order to protect pinctrldev_list.
  (Patrice).
- Sink mutex:es into some functions and remove some _locked
  variants down to where the lists are actually accessed to
  make things simpler. (Linus)
- Drop *all* mutexes completely from pinctrl_lookup_state()
  and pinctrl_select_state() - no relevant mutex was taken
  and it was unclear what this was protecting against. (Linus)

In commit b0de59b5 ("TTY: do not update atime/mtime on read/write")
we removed timestamps from tty inodes to fix a security issue and waited
if something breaks.  Well, 'w', the utility to find out logged users
and their inactivity time broke.  It shows that users are inactive since
the time they logged in.

To revert to the old behaviour while still preventing attackers to
guess the password length, we update the timestamps in one-minute
intervals by this patch.

The pci config space accessors on s390 are (now) smart enough to
figure out if a pci function is available. So instead of calling
pci_create_root_bus and then pci_scan_single_device for each
available function just call pci_scan_root_bus and let the pci core
do the scanning (via config reads on all possible functions) and
device creation.
