Add RapidIO enumeration/discovery start from user space. User space
start allows to defer RapidIO fabric scan until the moment when all
participating endpoints are initialized avoiding mandatory synchronized
start of all endpoints (which may be challenging in systems with large
number of RapidIO endpoints).

Systems that use RapidIO fabric may need to implement their own
enumeration and discovery methods which are better suitable for needs of
a target application.
The following set of patches is intended to simplify process of
introduction of new RapidIO fabric enumeration/discovery methods.
The first patch offers ability to add new RapidIO enumeration/discovery
methods using kernel configuration options. This new configuration
option mechanism allows to select statically linked or modular
enumeration/discovery method(s) from the list of existing methods or use
external module(s).
This patch also updates the currently existing enumeration/discovery
code to be used as a statically linked or modular method.
The corresponding configuration option is named "Basic
enumeration/discovery" method. This is the only one configuration
option available today but new methods are expected to be introduced
after adoption of provided patches.
The second patch address a long time complaint of RapidIO subsystem
users regarding fabric enumeration/discovery start sequence. Existing
implementation offers only a boot-time enumeration/discovery start which
requires synchronized boot of all endpoints in RapidIO network. While
it works for small closed configurations with limited number of
endpoints, using this approach in systems with large number of endpoints
is quite challenging.
To eliminate requirement for synchronized start the second patch
introduces RapidIO enumeration/discovery start from user space.
For compatibility with the existing RapidIO subsystem implementation,
automatic boot time enumeration/discovery start can be configured in by
specifying "rio-scan.scan=1" command line parameter if statically linked
basic enumeration method is selected.
This patch:
Rework to implement RapidIO enumeration/discovery method selection
combined with ability to use enumeration/discovery as a kernel module.
This patch adds ability to introduce new RapidIO enumeration/discovery
methods using kernel configuration options. Configuration option
mechanism allows to select statically linked or modular
enumeration/discovery method from the list of existing methods or use
external modules. If a modular enumeration/discovery is selected each
RapidIO mport device can have its own method attached to it.
The existing enumeration/discovery code was updated to be used as
statically linked or modular method. This configuration option is named
"Basic enumeration/discovery" method.
Several common routines have been moved from rio-scan.c to make them
available to other enumeration methods and reduce number of exported
symbols.

When reading a remote attribute, to correctly calculate the length
of the data buffer for CRC enable filesystems, we need to know the
length of the attribute data. We get this information when we look
up the attribute, but we don't store it in the args structure along
with the other remote attr information we get from the lookup. Add
this information to the args structure so we can use it
appropriately.

There are several places where we use KM_SLEEP allocation contexts
and use the fact that they are called from transaction context to
add KM_NOFS where appropriate. Unfortunately, there are several
places where the code makes this assumption but can be called from
outside transaction context but with filesystem locks held. These
places need explicit KM_NOFS annotations to avoid lockdep
complaining about reclaim contexts.

The logic to detect if the irq stack was already in use with
raw_spin_trylock() is wrong, because it will generate a "trylock failure
on UP" error message with CONFIG_SMP=n and CONFIG_DEBUG_SPINLOCK=y.
arch_spin_trylock() can't be used either since in the CONFIG_SMP=n case
no atomic protection is given and we are reentrant here. A mutex didn't
worked either and brings more overhead by turning off interrupts.
So, let's use the fastest path for parisc which is the ldcw instruction.
Counting how often the irq stack was used is pretty useless, so just
drop this piece of code.

The offset passed into xfs_free_file_space() needs to be rounded
down to a certain size, but the rounding mask is built by a 32 bit
variable. Hence the mask will always mask off the upper 32 bits of
the offset and lead to incorrect writeback and invalidation ranges.
This is not actually exposed as a bug because we writeback and
invalidate from the rounded offset to the end of the file, and hence
the offset we are actually punching a hole out of will always be
covered by the code. This needs fixing, however, if we ever want to
use exact ranges for writeback/invalidation here...

FSX on 512 byte block size filesystems has been failing for some
time with corrupted data. The fault dates back to the change in
the writeback data integrity algorithm that uses a mark-and-sweep
approach to avoid data writeback livelocks.
Unfortunately, a side effect of this mark-and-sweep approach is that
each page will only be written once for a data integrity sync, and
there is a condition in writeback in XFS where a page may require
two writeback attempts to be fully written. As a result of the high
level change, we now only get a partial page writeback during the
integrity sync because the first pass through writeback clears the
mark left on the page index to tell writeback that the page needs
writeback....
The cause is writing a partial page in the clustering code. This can
happen when a mapping boundary falls in the middle of a page - we
end up writing back the first part of the page that the mapping
covers, but then never revisit the page to have the remainder mapped
and written.
The fix is simple - if the mapping boundary falls inside a page,
then simple abort clustering without touching the page. This means
that the next ->writepage entry that write_cache_pages() will make
is the page we aborted on, and xfs_vm_writepage() will map all
sections of the page correctly. This behaviour is also optimal for
non-data integrity writes, as it results in contiguous sequential
writeback of the file rather than missing small holes and having to
write them a "random" writes in a future pass.
With this fix, all the fsx tests in xfstests now pass on a 512 byte
block size filesystem on a 4k page machine.

The get_stack_use_cr30 and get_stack_use_r30 macros allocate a stack
frame for external interrupts and interruptions requiring a stack frame.
They are currently not reentrant in that they save register context
before the stack is set or adjusted.
I have observed a number of system crashes where there was clear
evidence of stack corruption during interrupt processing, and as a
result register corruption. Some interruptions can still occur during
interruption processing, however external interrupts are disabled and
data TLB misses don't occur for absolute accesses. So, it's not entirely
clear what triggers this issue. Also, if an interruption occurs when
Q=0, it is generally not possible to recover as the shadowed registers
are not copied.
The attached patch reworks the get_stack_use_cr30 and get_stack_use_r30
macros to allocate stack before doing register saves. The new code is a
couple of instructions shorter than the old implementation. Thus, it's
an improvement even if it doesn't fully resolve the stack corruption
issue. Based on limited testing, it improves SMP system stability.

The umul_ppmm() macro for parisc uses the xmpyu assembler statement
which does calculation via a floating point register.
But usage of floating point registers inside the Linux kernel are not
allowed and gcc will stop compilation due to the -mdisable-fpregs
compiler option.
Fix this by disabling the umul_ppmm() and udiv_qrnnd() macros. The
mpilib will then use the generic built-in implementations instead.

This patch changes the multi-block allocation code, such that
directory inodes only get a single block reserved in the bitmap.
That way, the bitmaps are more tightly packed together, and there
are fewer spans of free blocks for in-use block reservations.
This means it takes less time to find a free span of blocks in the
bitmap, which speeds things up. This increases the performance of
some workloads by almost 2X. In Nate's mockup.py script (which does
(1) create dir, (2) create dir in dir, (3) create file in that dir)
the test executes in 23 steps rather than 43 steps, a 47%
performance improvement.

In function be_get_nic_desc(), it will go through the descriptor array
returned from f/w. By comparing the desc_type field, it determines whether
there is a nic descriptor in the array or not. In the case of no nic
descriptor, this function should return NULL.
The code may return an invalide descriptor, when there is no nic descriptor
in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case,
even there is no nic descriptor, it will still return the lase descriptor
since the i doesn't equal to MAX_RESOURCE_DESC.
This patch fix this issue by returning the descriptor when find it and return
NULL for other cases.

commit 3853b5841c01a ("xps: Improvements in TX queue selection")
introduced ooo_okay flag, but the condition to set it is slightly wrong.
In our traces, we have seen ACK packets being received out of order,
and RST packets sent in response.
We should test if we have any packets still in host queue.

Pull PCI updates from Bjorn Helgaas:
"Here are some more fixes for v3.10. The Moorestown update broke Intel
Medfield devices, so I reverted it. The acpiphp change fixes a
regression: we broke hotplug notifications to host bridges when we
split acpiphp into the host-bridge related part and the
endpoint-related part.

Pull tty/serial fixes from Greg Kroah-Hartman:
"Here are some tty / serial driver fixes for 3.10-rc2.
Nothing huge, although the rocket driver fix looks large, it's just
moving the code around to fix the reported build issues in it. Other
than that, this has the fix for the of-reported lockdep warning from
the vt layer, as well as some other needed bugfixes.
All of these have been in linux-next for a while"
