Fix handling of nested structs or unions. The regex to strip (eliminate)
nested structs or unions was limited to only 0 or 1 matches. This can
cause an uneven number of left/right braces to be stripped, which causes
this:

get_order() takes byte-sized input, not a page-granular one.
Irrespective of this fix I'm inclined to believe that this doesn't work
right anyway - bitmap_allocate_region() has an implicit assumption of
'pos' being suitable for 'order', which this function doesn't seem to
enforce (and since it's being called with a byte-granular value there's no
reason to believe that the callers would make sure device_addr is passed
accordingly - it's also not documented that way).

of_node_put is needed before discarding a value received from
of_find_node_by_type, eg in error handling code.

I have a new PCI-E radeon RV380 series card (PCI device ID 5b64) that
hangs in my sparc64 boxes when the init scripts set the font. The problem
goes away if I disable acceleration.
I haven't figured out that bug yet, but along the way I found some
corrections to make based upon some auditing.
1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver
and the XORG video driver differ. I've made the kernel
match what XORG is using.
2) In radeonfb_engine_reset() we have top-level code structure
that roughly looks like:
if (family is 300, 350, or V350)
do this;
else
do that;
...
if (family is NOT 300, OR
family is NOT 350, OR
family is NOT V350)
do another thing;
this last conditional makes no sense, is always true,
and obviously was likely meant to be "family is NOT
300, 350, or V350". So I've made the code match the
intent.

In relay's current read implementation, if the buffer is completely full
but hasn't triggered the buffer-full condition (i.e. the last write
didn't cross the subbuffer boundary) and the last subbuffer is exactly
full, the subbuffer accounting code erroneously finds nothing available.
This patch fixes the problem.

The current implementation reports the structure name as
VMCOREINFO_OSRELEASE in VMCOREINFO, e.g.
VMCOREINFO_OSRELEASE=init_uts_ns.name.release
That doesn't make sense because it's always the same. Instead, use the
value, e.g.
VMCOREINFO_OSRELEASE=2.6.26-rc3
That's also what the 'makedumpfile -g' does.

According to MMC-3 (or any later versions) READ TOCs are mandatory
commands and have nothing to do with CDC_PLAY_AUDIO. I have no idea why
the check was put there in the first place but it now only breaks
automatic actions on certain drives.
Note that this test was only effective when ide-cdrom was being used
as sr didn't mask CDC_PLAY_AUDIO according to the capabilities.

Aesthetic regards aside, commit e8e7b9eb11c34ee18bde8b7011af41938d1ad667
still leaves a bug in the error message, because it uses the unconverted
big-endian value for printk.
Fix this by using a local variable in machine byte order. The result is
correct, more readable, and also produces slightly shorter code on i386.

The guilty commit turned out to be 08da591e14cf87247ec09b17c350235157a92fc3
("ide: add ide_device_{get,put}() helpers"). ide_device_put() is called
before kref_put() in ide_cd_put() so IDE device is already gone by the time
ide_cd_release() is reached.
Fix it by calling ide_device_get() before kref_get() and ide_device_put()
after kref_put() in all affected device drivers.
v2:
Brown paper bag time. In v1 cd->drive was referenced after dropping last
reference on cd object (which could result in OOPS in ide_device_put() as
reported/debugged by Mariusz Kozlowski). Fix it by caching cd->drive in
the local variable (fix other device drivers too).

Fix byte-swapping for id->words161_175[], id->words206_254[]
and id->words206_254[].
Luckily all words previously left in little-endian byte-order
are marked as reserved so this fix shouldn't affect user-space
applications.

id->tDMA is of 'unsigned char' type so endianness is already
correct and calling le16_to_cpu() is wrong.

Okay, I found the cause of the hang. It is a simple bug in the USB
scatter-gather library, caused by changes added in response to the S-G
chaining modification.
This patch (as1125) fixes a bug in the USB scatter-gather library.
Early exit from the S-G initialization loop does not reset the count of
outstanding URBs.

Like the page lock change, this also requires name change, so convert the
raw test_and_set bitop to a trylock.

Converting page lock to new locking bitops requires a change of page flag
operation naming, so we might as well convert it to something nicer
(!TestSetPageLocked_Lock => trylock_page, SetPageLocked => set_page_locked).
This also facilitates lockdeping of page lock.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-2.6:
sparc64: Remove all cpumask_t local variables in xcall dispatch.
sparc64: Kill error_mask from hypervisor_xcall_deliver().
sparc64: Build cpu list and mondo block at top-level xcall_deliver().
sparc64: Disable local interrupts around xcall_deliver_impl() invocation.
sparc64: Make all xcall_deliver's go through common helper function.
sparc64: Always allocate the send mondo blocks, even on non-sun4v.
sparc64: Make smp_cross_call_masked() take a cpumask_t pointer.
sparc64: Directly call xcall_deliver() in smp_start_sync_tick_client.
sparc64: Call xcall_deliver() directly in some cases.
sparc64: Use cpumask_t pointers and for_each_cpu_mask_nr() in xcall_deliver.
sparc64: Use xcall_deliver() consistently.
sparc64: Use function pointer for cross-call sending.
arch/sparc64/kernel/signal.c: removed duplicated #include
sparc64: Need to disable preemption around smp_tsb_sync().

All of the xcall delivery implementation is cpumask agnostic, so
we can pass around pointers to const cpumask_t objects everywhere.
The sad remaining case is the argument to arch_send_call_function_ipi().

It can eat up a lot of stack space when NR_CPUS is large.
We retain some of it's functionality by reporting at least one
of the cpu's which are seen in error state.

Then modify all of the xcall dispatch implementations get passed and
use this information.
Now all of the xcall dispatch implementations do not need to be mindful
of details such as "is current cpu in the list?" and "is cpu online?"

This just facilitates the next changeset where we'll be building
the cpu list and mondo block in this helper function.
