ide: switch idedisk_prepare_flush() to use REQ_TYPE_ATA_TASKFILE requests

broke flush requests.
Allocating IDE command structure on the stack for flush requests is not
a very brilliant idea:
- idedisk_prepare_flush() only prepares the request and it doesn't wait
for it to be completed
- there are can be multiple flush requests queued in the queue
Fix the problem (per hints from James Bottomley) by:
- dynamically allocating ide_task_t instance using kmalloc(..., GFP_ATOMIC)
- adding new taskfile flag (IDE_TFLAG_DYN)
- calling kfree() in ide_end_drive_command() if IDE_TFLAG_DYN is set
(while at it rename 'args' to 'task' and fix whitespace damage)
[ This will be fixed properly before 2.6.25 but this bug is rather
critical and the proper solution requires some more work + testing. ]

NLM: set RPC_CLNT_CREATE_NOPING for NLM RPC clients
It's currently possible for an unresponsive NLM client to completely
lock up a server's lockd. The scenario is something like this:
1) client1 (or a process on the server) takes a lock on a file
2) client2 tries to take a blocking lock on the same file and
awaits the callback
3) client2 goes unresponsive (plug pulled, network partition, etc)
4) client1 releases the lock
...at that point the server's lockd will try to queue up a GRANT_MSG
callback for client2, but first it requeues the block with a timeout of
30s. nlm_async_call will attempt to bind the RPC client to client2 and
will call rpc_ping. rpc_ping entails a sync RPC call and if client2 is
unresponsive it will take around 60s for that to time out. Once it times
out, it's already time to retry the block and the whole process repeats.
Once in this situation, nlmsvc_retry_blocked will never return until
the host starts responding again. lockd won't service new calls.
Fix this by skipping the RPC ping on NLM RPC clients. This makes
nlm_async_call return quickly when called.

splice: fix user pointer access in get_iovec_page_array()
Commit
8811930dc74a503415b35c4a79d14fb0b408a361 ("splice: missing user
pointer access verification") added the proper access_ok() calls to
copy_from_user_mmap_sem() which ensures we can copy the struct iovecs
from userspace to the kernel.
But we also must check whether we can access the actual memory region
pointed to by the struct iovec to fix the access checks properly.

hrtimer: don't modify restart_block->fn in restart functions
hrtimer_nanosleep_restart() clears/restores restart_block->fn. This is
pointless and complicates its usage. Note that if sys_restart_syscall()

this is harmless.

hrtimer: fix *rmtp/restarts handling in compat_sys_nanosleep()
Spotted by Pavel Emelyanov and Alexey Dobriyan.
compat_sys_nanosleep() implicitly uses hrtimer_nanosleep_restart(), this can't
work. Make a suitable compat_nanosleep_restart() helper.

hrtimer: fix *rmtp handling in hrtimer_nanosleep()
Spotted by Pavel Emelyanov and Alexey Dobriyan.
hrtimer_nanosleep() sets restart_block->arg1 = rmtp, but this rmtp points to
the local variable which lives in the caller's stack frame. This means that
if sys_restart_syscall() actually happens and it is interrupted as well, we
don't update the user-space variable, but write into the already dead stack
frame.
Introduced by commit
04c227140fed77587432667a574b14736a06dd7f
hrtimer: Rework hrtimer_nanosleep to make sys_compat_nanosleep easier
Change the callers to pass "__user *rmtp" to hrtimer_nanosleep(), and change
hrtimer_nanosleep() to use copy_to_user() to actually update *rmtp.
Small problem remains. man 2 nanosleep states that *rtmp should be written if
nanosleep() was interrupted (it says nothing whether it is OK to update *rmtp
if nanosleep returns 0), but (with or without this patch) we can dirty *rem
even if nanosleep() returns 0.
NOTE: this patch doesn't change compat_sys_nanosleep(), because it has other
bugs. Fixed by the next patch.

htb_requeue() enqueues skbs for which htb_classify() returns NULL.
This is wrong because such skbs could be handled by NET_CLS_ACT code,

checkcard() is used by exported functions so it cannot be
annotated __devinit. Annotate it with __ref so modpost

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.

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 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.

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.

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

[ARM] 4824/1: pxa: clear RDH bit after any reset
According to PXA300/310 and PXA320 Developer manuals,
the ASCR[RDH] "bit needs to be cleared as part of the software
initialization coming out of any reset and coming out of D3".
The latter requirement is addressed by commit
"
c4d1fb627ff3072", as for the former (coming out of any reset),
the kernel relies on boot loaders and assumes that RDH bit
is cleared there. Though, not all bootloaders follow the rule
so we have to clear the bit in kernel.
We clear the RDH bit in pxa3xx_init() function since
it is always invoked after any reset. We also preserve D1S, D2S
and D3S bits from being cleared in case we invoke pxa3xx_init()
function not from normal hardware reset (e.g. kexec scenario),
so these bits can be properly referenced later.

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

x86: construct 32-bit boot time page tables in native format.
Specifically the boot time page tables in a CONFIG_X86_PAE=y enabled
kernel are in PAE format.
early_ioremap is updated to use the standard page table accessors.
Clear any mappings beyond max_low_pfn from the boot page tables in
native_pagetable_setup_start because the initial mappings can extend
beyond the range of physical memory and into the vmalloc area.
Derived from patches by Eric Biederman and H. Peter Anvin.
