f18573abcc block: move the padding adjustment to blk_rq_map_sg
blk_rq_map_user adjusts bi_size of the last bio. It breaks the rule
that req->data_len (the true data length) is equal to sum(bio). It
broke the scsi command completion code.

commit e97a294ef6 was introduced to fix
the above issue. However, the partial completion code doesn't work
with it. The commit is also a layer violation (scsi mid-layer should
not know about the block layer's padding).

This patch moves the padding adjustment to blk_rq_map_sg (suggested by
James). The padding works like the drain buffer. This patch breaks the
rule that req->data_len is equal to sum(sg), however, the drain buffer
already broke it. So this patch just restores the rule that
req->data_len is equal to sub(bio) without breaking anything new.

Now when a low level driver needs padding, blk_rq_map_user and
blk_rq_map_user_iov guarantee there's enough room for padding.
blk_rq_map_sg can safely extend the last entry of a scatter list.

blk_rq_map_sg must extend the last entry of a scatter list only for a
request that got through bio_copy_user_iov. This patches introduces
new REQ_COPY_USER flag.

476a4813cf loop: manage partitions in disk image
This patch allows to use loop device with partitionned disk image.

Original behavior of loop is not modified.

A new parameter is introduced to define how many partition we want to be
able to manage per loop device. This parameter is "max_part".

For instance, to manage 63 partitions / loop device, we will do:
# modprobe loop max_part=63
# ls -l /dev/loop?*
brw-rw---- 1 root disk 7,   0 2008-03-05 14:55 /dev/loop0
brw-rw---- 1 root disk 7,  64 2008-03-05 14:55 /dev/loop1
brw-rw---- 1 root disk 7, 128 2008-03-05 14:55 /dev/loop2
brw-rw---- 1 root disk 7, 192 2008-03-05 14:55 /dev/loop3
brw-rw---- 1 root disk 7, 256 2008-03-05 14:55 /dev/loop4
brw-rw---- 1 root disk 7, 320 2008-03-05 14:55 /dev/loop5
brw-rw---- 1 root disk 7, 384 2008-03-05 14:55 /dev/loop6
brw-rw---- 1 root disk 7, 448 2008-03-05 14:55 /dev/loop7

And to attach a raw partitionned disk image, the original losetup is used:

# losetup -f etch.img
# ls -l /dev/loop?*
brw-rw---- 1 root disk 7,   0 2008-03-05 14:55 /dev/loop0
brw-rw---- 1 root disk 7,   1 2008-03-05 14:57 /dev/loop0p1
brw-rw---- 1 root disk 7,   2 2008-03-05 14:57 /dev/loop0p2
brw-rw---- 1 root disk 7,   5 2008-03-05 14:57 /dev/loop0p5
brw-rw---- 1 root disk 7,  64 2008-03-05 14:55 /dev/loop1
brw-rw---- 1 root disk 7, 128 2008-03-05 14:55 /dev/loop2
brw-rw---- 1 root disk 7, 192 2008-03-05 14:55 /dev/loop3
brw-rw---- 1 root disk 7, 256 2008-03-05 14:55 /dev/loop4
brw-rw---- 1 root disk 7, 320 2008-03-05 14:55 /dev/loop5
brw-rw---- 1 root disk 7, 384 2008-03-05 14:55 /dev/loop6
brw-rw---- 1 root disk 7, 448 2008-03-05 14:55 /dev/loop7
# mount /dev/loop0p1 /mnt
# ls /mnt
bench  cdrom  home        lib         mnt   root     srv  usr
bin    dev    initrd      lost+found  opt   sbin     sys  var
boot   etc    initrd.img  media       proc  selinux  tmp  vmlinuz
# umount /mnt
# losetup -d /dev/loop0

Of course, the same behavior can be done using kpartx on a loop device,
but modifying loop avoids to stack several layers of block device (loop +
device mapper), this is a very light modification (40% of modifications
are to manage the new parameter).

22a9189fd0 cdrom: use kmalloced buffers instead of buffers on stack
If cdrom commands are issued to a scsi drive in most cases the buffer will be
filled via dma.  This leads to bad stack corruption on non coherent platforms,
because the buffers are neither cache line aligned nor is the size a multiple
of the cache line size.  Using kmalloced buffers avoids this.

ca99eb8c2d PCI: Hotplug: fakephp: Return success, not ENODEV, when bus rescan is triggered
The 'power' attribute of the fakephp driver originally only let one turn a
slot off.  If one tried to turn a slot on (echo 1 > .../power), it would
return ENODEV, as fakephp did not support this function.

An old (pre-git) patch changed this:
2004/11/11 16:33:31-08:00 jdittmer
[PATCH] fakephp: add pci bus rescan ability
http://article.gmane.org/gmane.linux.kernel/251183

Now writing "1" to the power attribute has the effect of triggering a bus
rescan, but it still returns ENODEV, probably an oversight in the above
patch.

Using the BusyBox echo will not produce an error message, but will
trigger *two* bus rescans (and return an exit code of 1):
~ # strace echo -n 1 > /sys/bus/pci/slots/0000:00:00.0/power
...
write(1, "1", 1)                        = -1 ENODEV (No such device)
write(1, "1", 1)                        = -1 ENODEV (No such device)
exit(1)                                 = ?

Using cp gives a write error, even though the write did happen and a rescan
was triggered:
~ # echo -n 1 > tmp ; cp tmp /sys/bus/pci/slots/0000:00:00.0/power
cp: Write Error: No such device

It seems much better to return success instead of failure.  The actual
status of the bus rescan is hard to return.  It happens asynchronously in a
work thread, so the sysfs store functions returns before any status is
ready (the whole point of the work queue).  And even if it didn't do this,
the rescan doesn't have any clear status to return.

029c3c133b PCI: Hotplug: Fix leaks in IBM Hot Plug Controller Driver - ibmphp_init_devno()
In drivers/pci/hotplug/ibmphp_core.c::ibmphp_init_devno() we allocate
space dynamically for a PCI irq routing table by calling
pcibios_get_irq_routing_table(), but we never free the allocated space.

This patch frees the allocated space at the function exit points.

Spotted by the Coverity checker. Compile tested only.

Please consider applying.

bc04327456 PCI: Update VIA CX700 quirk
This follows up 53a9bf4267. Some newer
CX700 BIOSes from our vendor have PCI Bus Parking disabled but PCI
Master read caching enabled. This creates problems such as system
freezing when both the network controller and the USB controller are
active and one of them is pretty busy (e.g. heavy network traffic).

This patch separates the checks and both the bus parking and the read
caching are disabled independently if either is enabled by the BIOS.

94e6108803 PCI: Expose PCI VPD through sysfs
Vital Product Data (VPD) may be exposed by PCI devices in several
ways.  It is generally unsafe to read this information through the
existing interfaces to user-land because of stateful interfaces.

This adds:
- abstract operations for VPD access (struct pci_vpd_ops)
- VPD state information in struct pci_dev (struct pci_vpd)
- an implementation of the VPD access method specified in PCI 2.2
  (in access.c)
- a 'vpd' binary file in sysfs directories for PCI devices with VPD
  operations defined

It adds a probe for PCI 2.2 VPD in pci_scan_device() and release of
VPD state in pci_release_dev().

5e0d2a6fc0 PCI: iommu: iotlb flushing
This patch is for batching up the flushing of the IOTLB for the DMAR
implementation found in the Intel VT-d hardware.  It works by building a list
of to be flushed IOTLB entries and a bitmap list of which DMAR engine they are
from.

After either a high water mark (250 accessible via debugfs) or 10ms the list
of iova's will be reclaimed and the DMAR engines associated are IOTLB-flushed.

This approach recovers 15 to 20% of the performance lost when using the IOMMU
for my netperf udp stream benchmark with small packets.  It can be disabled
with a kernel boot parameter "intel_iommu=strict".

Its use does weaken the IOMMU protections a bit.

ddf02886cb PCI: iova RB tree setup tweak
The following patch merges two functions into one allowing for a 3%
reduction in overhead in locating, allocating and inserting pages for
use in IOMMU operations.

Its a bit of a eye-crosser so I welcome any RB-tree / MM experts to take

search for the pages to use in setting up the IOTLB's in the insertion
of the iova structure into the RB tree.

Each architecture has its own pcibios_enable_resources() implementation.
These differ in many minor ways that have nothing to do with actual
architectural differences.  Follow-on patches will make most arches

This version is based on powerpc, which seemed most up-to-date.  The only
functional difference from the x86 version is that this uses "!r->parent"
to check for resource collisions instead of "!r->start && r->end".

7d715a6c1a PCI: add PCI Express ASPM support
PCI Express ASPM defines a protocol for PCI Express components in the D0
state to reduce Link power by placing their Links into a low power state
and instructing the other end of the Link to do likewise. This
capability allows hardware-autonomous, dynamic Link power reduction
beyond what is achievable by software-only controlled power management.
However, The device should be configured by software appropriately.
Enabling ASPM will save power, but will introduce device latency.

This patch adds ASPM support in Linux. It introduces a global policy for
ASPM, a sysfs file /sys/module/pcie_aspm/parameters/policy can control
it. The interface can be used as a boot option too. Currently we have
below setting:
        -default, BIOS default setting
        -powersave, highest power saving mode, enable all available ASPM
state and clock power management
        -performance, highest performance, disable ASPM and clock power
management
By default, the 'default' policy is used currently.

In my test, power difference between powersave mode and performance mode
is about 1.3w in a system with 3 PCIE links.

Note: some devices might not work well with aspm, either because chipset
issue or device issue. The patch provide API (pci_disable_link_state),
driver can disable ASPM for specific device.

semaphores during a suspend/hibernation to protect itself from
concurrent operations involving device objects.  That proved to be
too heavy-handed and we found a better way to achieve the goal, but
before it happened, we had introduced the functions
device_pm_schedule_removal() and destroy_suspended_device() to allow
drivers to "safely" destroy a suspended device and we had adapted some
drivers to use them.  Now that these functions are no longer necessary,
it seems reasonable to remove them and modify their users to use the
normal device unregistration instead.

d288e47c47 PM: Make wakeup flags available whenever CONFIG_PM is set
The various wakeup flags and their accessor macros in struct
dev_pm_info should be available whenever CONFIG_PM is enabled, not
just when CONFIG_PM_SLEEP is on.  Otherwise remote wakeup won't always
be configurable for runtime power management.  This patch (as1056b)
fixes the oversight.

David Brownell adds:
	More accurately, fixes the "regression" ... as noted sometime
	last summer, after 296699de6b
	introduced CONFIG_SUSPEND.  But that didn't make the regression
	list for that kernel, ergo the delay in fixing it.

Include dpm_sysfs_add() into device_pm_add(), in analogy with
device_pm_remove(), and modify device_add() to call the latter after

58aca23226 PM: Handle device registrations during suspend/resume
Modify the PM core to protect its data structures, specifically the
dpm_active list, from being corrupted if a child of the currently
suspending device is registered concurrently with its ->suspend()
callback.  In that case, since the new device (the child) is added
to dpm_active after its parent, the PM core will attempt to
suspend it after the parent, which is wrong.

Introduce a new member of struct dev_pm_info, called 'sleeping',
and use it to check if the parent of the device being added to
dpm_active has been suspended, in which case the device registration
fails.  Also, use 'sleeping' for checking if the ordering of devices
on dpm_active is correct.

Introduce variable 'all_sleeping' that will be set to 'true' once all
devices have been suspended and make new device registrations fail
until 'all_sleeping' is reset to 'false', in order to avoid having
unsuspended devices around while the system is going into a sleep state.

Remove pm_sleep_rwsem which is not necessary any more.

Special thanks to Alan Stern for discussions and suggestions that
lead to the creation of this patch.

da009f39f8 sysdev: detect multiple driver registrations
I've just found how easy it is to accidentally register a sysdev_driver for
two different classes.  When this happens, bad things happen as the
sysdev_driver structure keeps has the list entry for the driver
registration.

The following patch makes a WARN_ON() if this happens, although I think
BUG_ON or returning -EAGAIN could also be valid responses to this.

Fix following warning:
WARNING: vmlinux.o(.text+0x64609c): Section mismatch in reference from the function store_online() to the function .cpuinit.text:cpu_up()

store_online() is defined inside a HOTPLUG_CPU block so references are OK. 
Ignore references by annotating store_online() with __ref.

Note: This is needed because cpu_up() most likely should not have been
__cpuinit but all the hotplug cpu code misuses the __cpuinit annotation.

00a41db522 driver core: register_memory/unregister_memory clean ups and bugfix
register_memory()/unregister_memory() never gets called with
"root". unregister_memory() is accessing kobject_name of
the object just freed up. Since no one uses the code,
lets take the code out. And also, make register_memory() static.

Another bug fix - before calling unregister_memory()
remove_memory_block() gets a ref on kobject. unregister_memory()
need to drop that ref before calling sysdev_unregister().

b54f2863a2 UIO: Implement a UIO interface for the SMX Cryptengine
This patch implements a UIO interface for the SMX Cryptengine.

The Cryptengine found on the Nias Digital SMX board is best suited
for a UIO interface.  It is not wired in to the cryptographic API
as the engine handles it's own keys, algorithms, everything.  All
that we know about is that if there's room in the buffer, you can
write data to it and when there's data ready, you read it out again.

There isn't necessarily even any direct correlation between data
going in and data coming out again, the engine may consume or
generate data all on its own.

This driver is for proprietary hardware but we're always told to
submit the drivers anyway; here you are.  :-)

This is version 4 of this patch and addresses all issues raised by
Hans-Jürgen Koch and Paul Mundt in their reviews.  Slightly altered
is Paul's suggestion to use DRV_NAME and DRV_VERSION as the UIO
version and name.  While at the moment they are the same, there
is no reason for them to stay that way.  Nevertheless we now at
least provide a MODULE_VERSION macro to keep modinfo happy.

41588ba1ae tg3: 5701 DMA corruption fix
Herbert Xu's commit fb93134dfc, entitled
"[TCP]: Fix size calculation in sk_stream_alloc_pskb", has triggered a
bug in the 5701 where the 5701 DMA engine will corrupt outgoing
packets.  This problem only happens when the starting address of the
packet matches a certain range of offsets and only when the 5701 is
placed downstream of a particular Intel bridge.

This patch detects the problematic bridge and if present, readjusts the
starting address of the packet data to a dword aligned boundary.
