memcg: fix page_cgroup allocation

page_cgroup_init() is called from mem_cgroup_init(). But at this
point, we cannot call alloc_bootmem().
(and this caused panic at boot.)

This patch moves page_cgroup_init() to init/main.c.

Time table is following:
==
  parse_args(). # we can trust mem_cgroup_subsys.disabled bit after this.
  ....
  cgroup_init_early()  # "early" init of cgroup.
  ....
  setup_arch()         # memmap is allocated.
  ...
  page_cgroup_init();
  mem_init();   # we cannot call alloc_bootmem after this.
  ....
  cgroup_init() # mem_cgroup is initialized.
==

Before page_cgroup_init(), mem_map must be initialized. So,
I added page_cgroup_init() to init/main.c directly.

(*) maybe this is not very clean but
    - cgroup_init_early() is too early
    - in cgroup_init(), we have to use vmalloc instead of alloc_bootmem().
    use of vmalloc area in x86-32 is important and we should avoid very large
    vmalloc() in x86-32. So, we want to use alloc_bootmem() and added page_cgroup_init()
    directly to init/main.c

The __log_wait_for_space function sits in a loop checkpointing
transactions until there is sufficient space free in the journal.
However, if there are no transactions to be processed (e.g.  because the

Hidehiro Kawai [Wed, 22 Oct 2008 21:15:00 +0000 (14:15 -0700)]
jbd: fix error handling for checkpoint io

When a checkpointing IO fails, current JBD code doesn't check the error
and continue journaling.  This means latest metadata can be lost from both
the journal and filesystem.

This patch leaves the failed metadata blocks in the journal space and
aborts journaling in the case of log_do_checkpoint().  To achieve this, we
need to do:

1. don't remove the failed buffer from the checkpoint list where in
   the case of __try_to_free_cp_buf() because it may be released or
   overwritten by a later transaction
2. log_do_checkpoint() is the last chance, remove the failed buffer
   from the checkpoint list and abort the journal
3. when checkpointing fails, don't update the journal super block to
   prevent the journaled contents from being cleaned.  For safety,
   don't update j_tail and j_tail_sequence either
4. when checkpointing fails, notify this error to the ext3 layer so
   that ext3 don't clear the needs_recovery flag, otherwise the
   journaled contents are ignored and cleaned in the recovery phase
5. if the recovery fails, keep the needs_recovery flag
6. prevent cleanup_journal_tail() from being called between
   __journal_drop_transaction() and journal_abort() (a race issue
   between journal_flush() and __log_wait_for_space()

   >kobject_add_internal failed for acpi with -EEXIST, don't try to register

   In the above commit the "acpi.power_nocheck" module parameter is defined
in drivers/acpi/power.c file. As several module parameters using the same ACPI
prefix are defined in the different files(for example: power_nocheck is
defined in drivers/acpi/power.c,debug_layer/debug_level are defined in
drivers/acpi/debug.c) and there exists another module between them, the
warning message will be printed when using the current generic param code.
(In the function of param_sysfs_init).

   In fact when ACPI is selected, the drivers/acpi/power will also be compiled
as built-in kernel.So this issue can be fixed by the following approach.
   workaround it by adjusting the module link order in drivers/acpi/Makefile.
In such case the module parameter using the same prefix(ACPI) are put together
in the param data section.

   Of course the better solution is to fix it in generic param code related
with sysfs.

drm/i915: hold dev->struct_mutex and DRM lock during vblank ring operations

To synchronize clip lists with the X server, the DRM lock must be held while
looking at drawable clip lists. To synchronize with other ring access, the
ring mutex must be held while inserting commands into the ring.  Failure to
do the first resulted in easy visual corruption when moving windows, and the
second could have corrupted the ring with DRI2.

Grabbing the DRM lock involves using the DRM tasklet mechanism, grabbing the
ring mutex means potentially sleeping. Deal with both of these by always
running the tasklet from a work handler.

Also, protect from clip list changes since the vblank request was queued by

ACPICA: Fix possible memory leak, error exit path

Fixed two possible memory leaks in the error exit paths of
acpi_ut_update_objerct_reference() and
acpi_ut_walk_package_tree()
These functions are similar in that they use a stack of state objects in
order to eliminate recursion. The stack must be fully deallocated
if an error occurs.
