0efc22f3af bnx2x: remove not necessary compiler barrier
Access to fp->tx_bd_prod is protected by __netif_tx_lock, so we do not
need any barrier for that.

Update of fp->tx_bd_cons in bnx2x_tx_int() is not protected by lock, but
barrier() nor smb_mb() in bnx2x_tx_avail() not guarantee we will see
values that is written on other cpu. Ordering issues between
netif_tx_stop_queue(), netif_tx_queue_stopped(), fp->tx_bd_cons = bd_cons
and bnx2x_tx_avail() are already handled by smp_mb() in bnx2x_tx_int()
and bnx2x_start_xmit().

The request to create an mccq was being dispatched without

be5bce2bf5 net: davinci emac: use dma_{map, unmap}_single API for cache coherency
The davinci emac driver uses some ARM specific DMA APIs
for cache coherency which have been removed from kernel
with the 2.6.34 merge.

Modify the driver to use the dma_{map, unmap}_single() APIs
defined in dma-mapping.h

Without this fix, the driver fails to compile on Linus's
tree.

2ac55d41b5 Btrfs: cache the extent state everywhere we possibly can V2
This patch just goes through and fixes everybody that does

lock_extent()
blah
unlock_extent()

to use

lock_extent_bits()
blah
unlock_extent_cached()

and pass around a extent_state so we only have to do the searches once per
function.  This gives me about a 3 mb/s boots on my random write test.  I have
not converted some things, like the relocation and ioctl's, since they aren't
heavily used and the relocation stuff is in the middle of being re-written.  I
also changed the clear_extent_bit() to only unset the cached state if we are
clearing EXTENT_LOCKED and related stuff, so we can do things like this

lock_extent_bits()
clear delalloc bits
unlock_extent_cached()

without losing our cached state.  I tested this thoroughly and turned on
LEAK_DEBUG to make sure we weren't leaking extent states, everything worked out
fine.

5a1a3df1f6 Btrfs: cache ordered extent when completing io

run btrfs_lookup_ordered_extent, but btrfs_dec_test_ordered_pending does that
already, so we're searching twice when we don't have to.  This patch lets us
pass a btrfs_ordered_extent in to btrfs_dec_test_ordered_pending so if we do
complete io on that ordered extent we can just use the one we found then instead
of having to do another btrfs_lookup_ordered_extent.  This made my fio job with
the other patch go from 24 mb/s to 29 mb/s.

4125bf761c Btrfs: finish read pages in the order they are submitted
The endio is done at reverse order of bio vectors.

That means for a sequential read, the page first submitted will finish
last in a bio. Considering we will do checksum (making cache hot) for
every page, this does introduce delay (and chance to squeeze cache used
soon) for pages submitted at the begining.

I don't observe obvious performance difference with below patch at my
simple test, but seems more natural to finish read in the order they are
submitted.

bd4d108889 Btrfs: make df be a little bit more understandable
The way we report df usage is way confusing for everybody, including some other
utilities (bacula for one).  So this patch makes df a little bit more
understandable.  First we make used actually count the total amount of used
space in all space info's.  This will give us a real view of how much disk space
is in use.  Second, for blocks available, only count data space.  This makes
things like bacula work because it says 0 when you can no longer write anymore
data to the disk.  I think this is a nice compromise, since you will end up with
something like the following

[root@alpha ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
                      148G   30G  111G  21% /
/dev/sda1             194M  116M   68M  64% /boot
tmpfs                 985M   12K  985M   1% /dev/shm
/dev/mapper/VolGroup-LogVol02
                      145G  140G     0 100% /mnt/btrfs-test

Compare this with btrfsctl -i output

[root@alpha btrfs-progs-unstable]# ./btrfsctl -i /mnt/btrfs-test/
Metadata, DUP: total=4.62GB, used=2.46GB
System, DUP: total=8.00MB, used=24.00KB
Data: total=134.80GB, used=134.80GB
Metadata: total=8.00MB, used=0.00
System: total=4.00MB, used=0.00
operation complete

This way we show that there is no more data space to be used, but we have
another 5GB of space left for metadata.  Thanks,

940100a4a7 Btrfs: be more selective in the defrag ioctl
The btrfs defrag ioctl had some bugs around delalloc accounting, and it
wasn't properly skipping pages that were not in the mapping.

It wasn't properly clearing the page checked flag, which could make the
writeback code ignore the page forever while pinning it as dirty.

This commit fixes those problems and makes defrag a little smarter.  It
skips holes and it doesn't waste time defragging large extents.  If a
tiny extent comes before a very large extent, it will defrag both of
them to make sure the tiny extent ends up next to something big.

6ef5ed0d38 Btrfs: add ioctl and incompat flag to set the default mount subvol
This patch needs to go along with my previous patch.  This lets us set the
default dir item's location to whatever root we want to use as our default
mounting subvol.  With this we don't have to use mount -o subvol=<tree id>
anymore to mount a different subvol, we can just set the new one and it will
just magically work.  I've done some moderate testing with this, mostly just
switching the default mount around, mounting subvols and the default mount at
the same time and such, everything seems to work.  Thanks,

Older kernels would generally be able to still mount the filesystem with the
default subvolume set, but it would result in a different volume being mounted,
which could be an even more unpleasant suprise for users.  So if you set your
default subvolume, you can't go back to older kernels.  Thanks,

73f73415ca Btrfs: change how we mount subvolumes
This work is in preperation for being able to set a different root as the
default mounting root.

There is currently a problem with how we mount subvolumes.  We cannot currently
mount a subvolume of a subvolume, you can only mount subvolumes/snapshots of the
default subvolume.  So say you take a snapshot of the default subvolume and call
it snap1, and then take a snapshot of snap1 and call it snap2, so now you have

/
/snap1
/snap1/snap2

as your available volumes.  Currently you can only mount / and /snap1,
you cannot mount /snap1/snap2.  To fix this problem instead of passing
subvolid=<name> you must pass in subvolid=<treeid>, where <treeid> is
the tree id that gets spit out via the subvolume listing you get from
the subvolume listing patches (btrfs filesystem list).  This allows us
to mount /, /snap1 and /snap1/snap2 as the root volume.

In addition to the above, we also now read the default dir item in the
tree root to get the root key that it points to.  For now this just
points at what has always been the default subvolme, but later on I plan
to change it to point at whatever root you want to be the new default
root, so you can just set the default mount and not have to mount with
-o subvolid=<treeid>.  I tested this out with the above scenario and it
worked perfectly.  Thanks,

mount -o subvol operates inside the selected subvolid.  For example:

mount -o subvol=snap1,subvolid=256 /dev/xxx /mnt

/mnt will have the snap1 directory for the subvolume with id
256.

mount -o subvol=snap /dev/xxx /mnt

/mnt will be the snap directory of whatever the default subvolume
is.

0d3a940de5 pcmcia: re-route Cardbus IRQ to ISA on ti1130 bridges if necessary
As the PCI irq pin of the ti1130 pcmcia bridge is not connected (at
least on some old IBM Thinkpad 760ED notebooks), the Cardbus IRQ has
to be routed to an ISA irq.

Part 3 of a series to allow the ISA irq to be used for Cardbus devices
if the socket's PCI irq is unusable.

ba8819e991 pcmcia: allow for cb_irq to differ from pci_dev's irq in yenta_socket
cb_irq is presumed to be the same as the pci_dev's irq. This won't be
true any more as soon as we allow the ISA irq to be used for Cardbus
devices. Therefore, use the pci_dev's irq explicitely whenever we
care about it.

Part 2 of a series to allow the ISA irq to be used for Cardbus devices
if the socket's PCI irq is unusable.

28ca8dd71f pcmcia: honor saved flags in yenta_socket's I365_CSCINT register
Instead of overwriting the I365_CSCINT register, save the old value and
merely change the bits we care about.

Part 1 of a series to allow the ISA irq to be used for Cardbus devices
if the socket's PCI irq is unusable.

b416cd8efb pcmcia: revert "irq probe can be done without risking an IRQ storm"
This reverts commit 635416ef39. The
argument passed to request_irq() only affects action->flags (IRQF_*),
but IRQ_NOAUTOEN relates to desc->status.

7a96e87d6e pcmcia: pd6729, i82092: use parent (PCI) resources
A newly added parent resource entry for the root PCI bus, such as

40000000-ffffffff : PCI Bus #00

means that the pd6729 and i82092 drivers cannot allocate iomem as
freely as before, unless they do so as PCI devices. Therefore, set
socket->cb_dev so that rsrc_nonstatic.c does the right thing.
