[ARM] 4304/1: removes the unnecessary bit number from CKENnn_XXXX
This patch removes the unnecessary bit number from CKENnn_XXXX
definitions for PXA, so that
CKEN0_PWM0 --> CKEN_PWM0
CKEN1_PWM1 --> CKEN_PWM1
...
CKEN24_CAMERA --> CKEN_CAMERA
The reasons for the change of these defitions are:
1. they do not scale - they are currently valid for pxa2xx, but
definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera
instead of bit 24
2. they are unnecessary - the peripheral name within the definition
has already announced its usage, we don't need those bit numbers
to know which peripheral we are going to enable/disable clock for
3. they are inconvenient - think about this: a driver programmer
for pxa has to remember which bit in the CKEN register to turn
on/off
Another change in the patch is to make the definitions equal to its
clock bit index, so that
#define CKEN_CAMERA (24)
instead of
#define CKEN_CAMERA (1 << 24)
this change, however, will add a run-time bit shift operation in
pxa_set_cken(), but the benefit of this change is that it scales
when bit index exceeds 32, e.g., pxa3xx has two registers CKENA
and CKENB, totally 64 bit for this, suppose CAMERA clock enabling
bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10)
and so that pxa_set_cken() need minimum change to adapt to that.

[ARM] 4246/1: i2c-pxa: add adapter class to platform specific data
Reposted patch for kernel 2.6.21-rc2.
The driver i2c-pxa doesn't set the class member in i2c_adapter, which
is used to register the I2C adapter. The hwmon (sensors) drivers (e.g.
adm1021) that are connected to a i2c-pxa adapter don't attach because
they expect that the adapter supports class I2C_CLASS_HWMON.
This patch adds functionality to allow platforms to set the class and
pass it as platform_data to the i2c-pxa driver. Sample usage in
platform code:
static struct i2c_pxa_platform_data my_i2c_platform_data = {
.class = I2C_CLASS_HWMON
};
static void __init my_platform_init(void)

spidernet: Fix problem sending IP fragments
The basic structure of "normal" UDP/IP/Ethernet
frames (that actually work):
- It starts with the Ethernet header (dest MAC, src MAC, etc.)
- The next part is occupied by the IP header (version info, length of
packet, id=0, fragment offset=0, checksum, from / to address, etc.)
- Then comes the UDP header (src / dest port, length, checksum)
- Actual payload
- Ethernet checksum
Now what's different for IP fragment:
- The IP header has id set to some value (same for all fragments),
offset is set appropriately (i.e. 0 for first fragment, following
according to size of other fragments), size is the length of the frame.
- UDP header is unchanged. I.e. length is according to full UDP
datagram, not just the part within the actual frame! But this is only
true within the first frame: all following frames don't have a valid
UDP-header at all.
The spidernet silicon seems to be quite intelligent: It's able to
compute (IP / UDP / Ethernet) checksums on the fly and tests if frames
are conforming to RFC -- at least conforming to RFC on complete frames.
But IP fragments are different as explained above:
I.e. for IP fragments containing part of a UDP datagram it sees
incompatible length in the headers for IP and UDP in the first frame
and, thus, skips this frame. But the content *is* correct for IP
fragments. For all following frames it finds (most probably) no valid
UDP header at all. But this *is* also correct for IP fragments.
The Linux IP-stack seems to be clever in this point. It expects the
spidernet to calculate the checksum (since the module claims to be able
to do so) and marks the skb's for "normal" frames accordingly
(ip_summed set to CHECKSUM_HW).
But for the IP fragments it does not expect the driver to be capable to
handle the frames appropriately. Thus all checksums are allready
computed. This is also flaged within the skb (ip_summed set to
CHECKSUM_NONE).
Unfortunately the spidernet driver ignores that hints. It tries to send
the IP fragments of UDP datagrams as normal UDP/IP frames. Since they
have different structure the silicon detects them the be not
"well-formed" and skips them.
The following one-liner against 2.6.21-rc2 changes this behavior. If the
IP-stack claims to have done the checksumming, the driver should not
try to checksum (and analyze) the frame but send it as is.

when an error is signalled on the socket, irda_recvmsg_stream returns
without removing a local wait_queue variable from the socket's sk_sleep
queue. This causes havoc further down the road.
In response to this problem, a patch was made that invoked sock_orphan on
the socket when receiving a disconnect indication. This is not a good fix,
as this sets sk_sleep to NULL, causing applications sleeping in recvmsg

queues where things live duing partial delivery, and the
message will be delivered to the socket in the middle of partial delivery.
This is a two-fold problem, in that:
1. the app now must check the stream-id and flags which it may not

2. this clearing partial delivery state from the association and results

alpha: more fixes for specific machine types
arch/alpha/kernel/sys_sx164.c
Earlier firmware revisions need MVI fix as well.
arch/alpha/kernel/sys_nautilus.c
On UP1500 firmware reports wrong AGP IRQ (10 instead of 5).
This causes interrupt storm if there is a PCI device that
uses IRQ 5.

IB/mthca: Fix data corruption after FMR unmap on Sinai
In mthca_arbel_fmr_unmap(), the high bits of the key are masked off.
This gets rid of the effect of adjust_key(), which makes sure that
bits 3 and 23 of the key are equal when the Sinai throughput
optimization is enabled, and so it may happen that an FMR will end up
with bits 3 and 23 in the key being different. This causes data
corruption, because when enabling the throughput optimization, the
driver promises the HCA firmware that bits 3 and 23 of all memory keys
will always be equal.
Fix by re-applying adjust_key() after masking the key.

[VLAN]: Allow VLAN interface on top of bridge interface
When a VLAN interface is created on top of a bridge interface and
netfilter is enabled to see the bridged packets, the packets can be
corrupted when passing through the netfilter code. This is caused by the
VLAN driver not setting the 'protocol' and 'nh' members of the sk_buff
structure. In general, this is no problem as the VLAN interface is mostly
connected to a physical ethernet interface which does not use the
'protocol' and 'nh' members. For a bridge interface, however, these
members do matter.

[PATCH] autofs4: fix race in unhashed dentry code
Commit
f50b6f8691cae2e0064c499dd3ef3f31142987f0 introduced a race in
autofs4 between autofs_lookup_unhashed() and autofs_dentry_release().
autofs_dentry_release() ends up clearing the ->dentry and ->inode members
of autofs_info before removing it from the rehash list. The list is
protected by the rehash lock in both functions, but since
autofs_dentry_release() starts tearing the autofs_info struct down before
removing it from the list, autofs_lookup_unhashed() can get a autofs_info
with a NULL dentry.
This patch moves the clearing of ->dentry and ->inode after the removal
from the rehash list.

[SPARC]: avoid CHILD_MAX and OPEN_MAX constants
I don't figure anyone really cares about SunOS syscall emulation, and I
certainly don't. But I'm getting rid of uses of the OPEN_MAX and CHILD_MAX
compile-time constant, and these are almost the only ones. OPEN_MAX is a
bogus constant with no meaning about anything. The RLIMIT_NOFILE resource
limit is what sysconf (_SC_OPEN_MAX) actually wants to return.
The CHILD_MAX cases weren't actually using anything I want to get rid of,
but I noticed that they are there and are wrong too. The CHILD_MAX value
is not really unlimited as a -1 return from sysconf indicates. The
RLIMIT_NPROC resource limit is what sysconf (_SC_CHILD_MAX) wants to return.

[SPARC64]: Fix SBUS IOMMU allocation code.
There are several IOMMU allocator bugs. Instead of trying to fix this
overly complicated code, just mirror the PCI IOMMU arena allocator
which is very stable and well stress tested.
I tried to make the code as identical as possible so we can switch
sun4u PCI and SBUS over to a common piece of IOMMU code. All that
will be need are two callbacks, one to do a full IOMMU flush and one
to do a streaming buffer flush.
This patch gets rid of a lot of hangs and mysterious crashes on SBUS
