30ddb159ff [PKT_SCHED] ematch: Fix build warning.
Commit 954415e33e ("[PKT_SCHED] ematch:
tcf_em_destroy robustness") removed a cast on em->data when
passing it to kfree(), but em->data is an integer type that can
hold pointers as well as other values so the cast is necessary.

21347456ab [NET_SCHED] sch_htb: htb_requeue fix
htb_requeue() enqueues skbs for which htb_classify() returns NULL.
This is wrong because such skbs could be handled by NET_CLS_ACT code,
and the decision could be different than earlier in htb_enqueue().
So htb_requeue() is changed to work and look more like htb_enqueue().

WARNING: drivers/isdn/hisax/built-in.o(.text+0x19723): Section mismatch in reference from the function ISACVersion() to the variable .devinit.data:ISACVer
WARNING: drivers/isdn/hisax/built-in.o(.text+0x2005b): Section mismatch in reference from the function setup_avm_a1_pcmcia() to the function .devinit.text:setup_isac()

ISACVer were only used from function annotated __devinit
so add same annotation to ISACVer.
One af the fererencing functions missed __devinit so add it
and kill an additional warning.

checkcard() are the only user of hisax_cs_setup_card().
And checkcard is only used during init or when hot plugging
ISDN devices. So annotate hisax_cs_setup_card() with __devinit.
checkcard() is used by exported functions so it cannot be
annotated __devinit. Annotate it with __ref so modpost
ignore references to _devinit section.

initisar(), initisac() and clear_pending_isac_ints()
were all used via a cardmsg fnction - which may be called
ouside __devinit context.
So remove the bogus __devinit annotation of the
above three functions to fix the warnings.

7740ac6a7c isdn: fix section mismatch warning in hfc_sx.c

WARNING: drivers/isdn/hisax/built-in.o(.text+0x35818): Section mismatch in reference from the function hfcsx_card_msg() to the function .devinit.text:inithfcsx()

hfcsx_card_msg() may be called outside __devinit context.
Following the program logic is looks like the CARD_INIT branch
will only be taken under __devinit context but to be consistent
remove the __devinit annotation of inithfcsx() so we
do not mix non-__devinit and __devinit code.

469108ff3d ext4: Add new "development flag" to the ext4 filesystem
This flag is simply a generic "this is a crash/burn test filesystem"
marker.  If it is set, then filesystem code which is "in development"
will be allowed to mount the filesystem.  Filesystem code which is not
considered ready for prime-time will check for this flag, and if it is
not set, it will refuse to touch the filesystem.

As we start rolling ext4 out to distro's like Fedora, et. al, this makes
it less likely that a user might accidentally start using ext4 on a
production filesystem; a bad thing, since that will essentially make it
be unfsckable until e2fsprogs catches up.

256bdb497c ext4: allocate struct ext4_allocation_context from a kmem cache
struct ext4_allocation_context is rather large, and this bloats
the stack of many functions which use it.  Allocating it from
a named slab cache will alleviate this.

For example, with this change (on top of the noinline patch sent earlier):

-ext4_mb_new_blocks		200
+ext4_mb_new_blocks		 40

-ext4_mb_free_blocks		344
+ext4_mb_free_blocks		168

-ext4_mb_release_inode_pa	216
+ext4_mb_release_inode_pa	 40

-ext4_mb_release_group_pa	192
+ext4_mb_release_group_pa	 24

Most of these stack-allocated structs are actually used only for
mballoc history; and in those cases often a smaller struct would do.
So changing that may be another way around it, at least for those
functions, if preferred.  For now, in those cases where the ac
is only for history, an allocation failure simply skips the history
recording, and does not cause any other failures.

c4e35e07af JBD2: Clear buffer_ordered flag for barried IO request on success
In JBD2 jbd2_journal_write_commit_record(), clear the buffer_ordered
flag for the bh after barried IO has succeed. This prevents later, if
the same buffer head were submitted to the underlying device, which has
been reconfigured to not support barrier request, the JBD2 commit code
could treat it as a normal IO (without barrier).

This is a port from JBD/ext3 fix from Neil Brown.

More details from Neil:

Some devices - notably dm and md - can change their behaviour in
response to BIO_RW_BARRIER requests.  They might start out accepting
such requests but on reconfiguration, they find out that they cannot
any more. JBD2 deal with this by always testing if BIO_RW_BARRIER
requests fail with EOPNOTSUPP, and retrying the write
requests without the barrier (probably after waiting for any pending
writes to complete).

However there is a bug in the handling this in JBD2 for ext4 .

When ext4/JBD2 to submit a BIO_RW_BARRIER request,
it sets the buffer_ordered flag on the buffer head.
If the request completes successfully, the flag STAYS SET.

Other code might then write the same buffer_head after the device has
been reconfigured to not accept barriers.  This write will then fail,
but the "other code" is not ready to handle EOPNOTSUPP errors and the
error will be treated as fatal.

7fb5409df0 ext4: Fix Direct I/O locking
We cannot start transaction in ext4_direct_IO() and just let it last
during the whole write because dio_get_page() acquires mmap_sem which
ranks above transaction start (e.g. because we have dependency chain
mmap_sem->PageLock->journal_start, or because we update atime while
holding mmap_sem) and thus deadlocks could happen. We solve the problem
by starting a transaction separately for each ext4_get_block() call.

We *could* have a problem that we allocate a block and before its data
are written out the machine crashes and thus we expose stale data. But
that does not happen because for hole-filling generic code falls back to
buffered writes and for file extension, we add inode to orphan list and
thus in case of crash, journal replay will truncate inode back to the
original size.

In order to prevent a circular locking dependency when an unlink

This does not take overlapping regions into account. So we might end up

76ebd0548d x86: introduce page pool in cpa
DEBUG_PAGEALLOC was not possible on 64-bit due to its early-bootup
hardcoded reliance on PSE pages, and the unrobustness of the runtime
splitup of large pages. The splitup ended in recursive calls to
alloc_pages() when a page for a pte split was requested.

Avoid the recursion with a preallocated page pool, which is used to
split up large mappings and gets refilled in the return path of
kernel_map_pages after the split has been done. The size of the page
pool is adjusted to the available memory.

This part just implements the page pool and the initialization w/o
using it yet.

9b706aee7d x86: trivial printk optimizations
In arch/x86/boot/printf.c gets rid of unused tail of digits: const char
*digits = "0123456789abcdefghijklmnopqrstuvwxyz"; (we are using 0-9a-f
only)

Uses smaller/faster lowercasing (by ORing with 0x20)
if we know that we work on numbers/digits. Makes
strtoul smaller, and also we are getting rid of

  static const char small_digits[] = "0123456789abcdefx";
  static const char large_digits[] = "0123456789ABCDEFX";

since this works equally well:

  static const char digits[16] = "0123456789ABCDEF";

Size savings:

$ size vmlinux.org vmlinux
   text    data     bss     dec     hex filename
 877320  112252   90112 1079684  107984 vmlinux.org
 877048  112252   90112 1079412  107874 vmlinux

It may be also a tiny bit faster because code has less
branches now, but I doubt it is measurable.
