It seems that using ath9k_hw_stoppcurecv to stop rx dma is not enough.
When it's time to stop DMA, the PCU is still busy, so the rx enable
bit never clears.
Using ath9k_hw_abortpcurecv helps with getting rx stopped much faster,
with this change, I cannot reproduce the rx stop related WARN_ON anymore.

We now:
* check for a v3 controller before setting 8-bit bus width
* offer a callback for platform code to switch to 8-bit mode, which
allows non-v3 controllers to support it
* rely on mmc->caps |= MMC_CAP_8_BIT_DATA; in platform code to specify
that the board designers have indeed brought out all the pins for
8-bit to the slot.
We were previously relying only on whether the *controller* supported
8-bit, which doesn't tell us anything about the pin configuration in
the board design.
This fixes the MMC card regression reported by Maxim Levitsky here:
http://thread.gmane.org/gmane.linux.kernel.mmc/4336
by no longer assuming that 8-bit works by default.

When we allocate a vector for MSI/MSI-X we save away the PIRQ, and the
vector value. When we unmap (de-allocate) the MSI/MSI-X vector(s) we
need to provide the PIRQ and the vector value. What we did instead
was to provide the GSI (which was zero) and the vector value, and we
got these unhappy error messages:
(XEN) irq.c:1575: dom0: pirq 0 not mapped
[ 7.733415] unmap irq failed -22
This patches fixes this and we use the PIRQ value instead of the GSI
value.

Some aspects of PHY initialization are board dependent, things like
indicator LED connections and some clocking modes cannot be determined
by probing. The dev_flags element of struct phy_device can be used to
control these things if an appropriate value can be passed from the
Ethernet driver. We run into problems however if the PHY connections
are specified by the device tree. There is no way for the Ethernet
driver to know what flags it should pass.
If we are using the device tree, the struct phy_device will be
populated with the device tree node corresponding to the PHY, and we
can extract extra configuration information from there.
The next question is what should the format of that information be?
It is highly device specific, and the device tree representation
should not be tied to any arbitrary kernel defined constants. A
straight forward representation is just to specify the exact bits that
should be set using the "marvell,reg-init" property:
phy5: ethernet-phy@5 {
reg = <5>;
compatible = "marvell,88e1149r";
marvell,reg-init =
/* led[0]:1000, led[1]:100, led[2]:10, led[3]:tx */
<3 0x10 0 0x5777>, /* Reg 3,16 <- 0x5777 */
/* mix %:0, led[0123]:drive low off hiZ */
<3 0x11 0 0x00aa>, /* Reg 3,17 <- 0x00aa */
/* default blink periods. */
<3 0x12 0 0x4105>, /* Reg 3,18 <- 0x4105 */
/* led[4]:rx, led[5]:dplx, led[45]:drive low off hiZ */
<3 0x13 0 0x0a60>; /* Reg 3,19 <- 0x0a60 */
};
phy6: ethernet-phy@6 {
reg = <6>;
compatible = "marvell,88e1118";
marvell,reg-init =
/* Fix rx and tx clock transition timing */
<2 0x15 0xffcf 0>, /* Reg 2,21 Clear bits 4, 5 */
/* Adjust LED drive. */
<3 0x11 0 0x442a>, /* Reg 3,17 <- 0442a */
/* irq, blink-activity, blink-link */
<3 0x10 0 0x0242>; /* Reg 3,16 <- 0x0242 */
};
The Marvell PHYs have a page select register at register 22 (0x16), we
can specify any register by its page and register number. These are
the first and second word. The third word contains a mask to be ANDed
with the existing register value, and the fourth word is ORed with the
result to yield the new register value. The new marvell_of_reg_init
function leaves the page select register unchanged, so a call to it
can be dropped into the .config_init functions without unduly
affecting the state of the PHY.
If CONFIG_OF_MDIO is not set, there is no of_node, or no
"marvell,reg-init" property, the PHY initialization is unchanged.

Driver appears to be mistaking the permission field with default value
in the case of debug and qlge_irq_type.
Driver is also passing debug as a bitmask into netif_msg_init()
which wants a number of bits. Ron Mercer suggests we should
change this to pass in -1 so the defaults get used instead,
which makes the default much less verbose.

. Fix PulseAudio "ALSA driver bug" issue
(if we have two alternated areas within a 64k DMA buffer, then max
period size should obviously be 32k only).
Back references:
http://pulseaudio.org/wiki/AlsaIssueshttp://fedoraproject.org/wiki/Features/GlitchFreeAudio
. In stop timer function, need to supply ACK in the timer control byte.
. Minor log output correction
When I did my first PA testing recently, the period size bug resulted
in quite precisely observeable half-period-based playback distortion.
PA-based operation is quite a bit more underrun-prone (despite its
zero-copy optimizations etc.) than raw ALSA with this rather spartan
sound hardware implementation on my puny Athlon.
Note that even with this patch, azt3328 still doesn't work for both
cases yet, PA tsched=0 and tsched
(on tsched=0 it will playback tiny fragments of periods, leading to tiny
stuttering sounds with some pauses in between, whereas with
timer-scheduled operation playback works fine - minus some quite increased
underrun trouble on PA vs. ALSA, that is).

Since we walk up the path logging all of the parts of the inode's path, we need

everything. btrfs_log_dentry_safe does dget_parent and all of that jazz, but we

There are lots of places where we do dentry->d_parent->d_inode without holding

going to use it's inode and then dput it at the end.

People kept reporting NFS issues, specifically getting ESTALE alot. I figured
out how to reproduce the problem
SERVER
mkfs.btrfs /dev/sda1
mount /dev/sda1 /mnt/btrfs-test
<add /mnt/btrfs-test to /etc/exports>
btrfs subvol create /mnt/btrfs-test/foo
service nfs start
CLIENT
mount server:/mnt/btrfs /mnt/test
cd /mnt/test/foo
ls
SERVER
echo 3 > /proc/sys/vm/drop_caches
CLIENT
ls <-- get an ESTALE here
This is because the standard way to lookup a name in nfsd is to use readdir, and
what it does is do a readdir on the parent directory looking for the inode of
the child. So in this case the parent being / and the child being foo. Well
subvols all have the same inode number, so doing a readdir of / looking for
inode 256 will return '.', which obviously doesn't match foo. So instead we
need to have our own .get_name so that we can find the right name.
Our .get_name will either lookup the inode backref or the root backref,
whichever we're looking for, and return the name we find. Running the above
reproducer with this patch results in everything acting the way its supposed to.
