tcp_splice_read() doesnt take into account socket's O_NONBLOCK flag
Before this patch :
splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE);
causes a random endless block (if pipe is full) and
splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE | SPLICE_F_NONBLOCK);
will return 0 immediately if the TCP buffer is empty.
User application has no way to instruct splice() that socket should be in blocking mode
but pipe in nonblock more.
Many projects cannot use splice(tcp -> pipe) because of this flaw.
http://git.samba.org/?p=samba.git;a=history;f=source3/lib/recvfile.c;h=ea0159642137390a0f7e57a123684e6e63e47581;hb=HEAD
http://lkml.indiana.edu/hypermail/linux/kernel/0807.2/0687.html
Linus introduced SPLICE_F_NONBLOCK in commit 29e350944fdc2dfca102500790d8ad6d6ff4f69d
(splice: add SPLICE_F_NONBLOCK flag )
It doesn't make the splice itself necessarily nonblocking (because the
actual file descriptors that are spliced from/to may block unless they
have the O_NONBLOCK flag set), but it makes the splice pipe operations
nonblocking.
Linus intention was clear : let SPLICE_F_NONBLOCK control the splice pipe mode only
This patch instruct tcp_splice_read() to use the underlying file O_NONBLOCK
flag, as other socket operations do.
Users will then call :
splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE | SPLICE_F_NONBLOCK );
to block on data coming from socket (if file is in blocking mode),
and not block on pipe output (to avoid deadlock)

The problem is that the chchp --vary 0 leads to zfcp first calling
fc_remote_port_delete which blocks all scsi devices on the remote
port. Calling scsi_remove_device later lets the sd driver issue a
SYNCHRONIZE_CACHE command. This command stays on the "stopped" request
requeue because the SCSI device is blocked. Fix this by first removing
the scsi and fc hosts which removes all scsi devices and do not use
scsi_remove_device.

cancel_work_sync is called while holding the config_mutex. But the
work that is being cancelled or flushed also uses the config_mutex.
Fix the resulting deadlock possibility by calling cancel_work_sync
earlier without holding the mutex. The best place to do is is after
offlining the device. No new port scan work will be scheduled for the
offline device, so this is a safe place to call cancel_work_sync.

With the change that the zfcp_adapter struct is only allocated when
the device is set online, the shutdown handler has to check for a
non-existing zfcp_adapter struct. On the other hand, this check is not
necessary in the offline callback, since an online device has the
zfcp_adapter allocated and we go through the offline callback before
removing the ccw device.

firmware to ACK.
Following a diag_reset, a request to send an ioc_init is timing out. The
timeout occurred within the HANDSHAKE logic while waiting on firmware to
acknowledge that the driver had wrote to the doorbell register. This was
root caused to a logic timeout in the firmware code. The proposed solution
is for the driver to call the udelay instead of msleep API in function where
its looping reading the interrupt status. In addition to this change, there
were two additional cases where we deleted the clearing interrupt status
outside handshake context.

(1) Added three new functions to handle sending target resest and OP_REMOVE
from interrupt time, they are _scsih_tm_tr_send, _scsih_tm_tr_complete, and
_scsih_sas_control_complete. This code will create a link list of pending
target resets if there is no more available request in the hipriority
request queue. The list is stored in ioc->delayed_tr_list.
(2) All callback handler return type is changed from void to u8.
Now _base_interrupt will check for return type of callback handlers to
take decision of message frame is already freed or not.
In genral,
Return 1 meaning mf should be freed from _base_interrupt
0 means the mf is freed from function.

support multiple TM
1) create a pool of high priority message frames in the region of memory
between message frames and chains. The modifications are in
_base_allocate_memory_pools. Also create a seperate pool of memory for
internal commands located near the same region of memory. The pool of high
priority message frames is restriced by the facts->HighPriorityCredit.
2) Create additional API for accessing request message frames. New function
mpt2sas_base_get_smid_hpr is for highpriority request. New function
mpt2sas_base_get_smid_scsiio for SCSI_IO, passing in the scsi command
pointer. The mpt2sas_base_get_smid function is for requesting internal
commands.
3) Added new function _base_get_cb_idx to obtain the callback
index from one of the three pools of request message frames.
4) Removed wrapper functions _scsih_scsi_lookup_set and
_scsih_scsi_lookup_getclear. These were removed because this handling was
moved into mpt2sas_base_get_smid_scsiio and mpt2sas_base_free_smid.
5) The function mpt2sas_base_free_smid is modified so the request message
frames are put back on one of the three pools of request message frames.

architecture type (e.g. x86 = 4K, IA64 = 16K) and by choice lets device use
the defaults. So while mapping connection context memory (doorebll registers),
driver has to match page size used by the device. Included change fixes the

Make decoding of MCEs happen only on AMD hardware by registering a
non-default callback only on CPU families which support it.
While looking at the interaction of decode_mce() with the other MCE
code i also noticed a few other things and made the following
cleanups/fixes:
- Fixed the mce_decode() weak alias - a weak alias is really not
good here, it should be a proper callback. A weak alias will be
overriden if a piece of code is built into the kernel - not
good, obviously.
- The patch initializes the callback on AMD family 10h and 11h.
- Added the more correct fallback printk of:
No support for human readable MCE decoding on this CPU type.
Transcribe the message and run it through 'mcelog --ascii' to decode.
On CPUs that dont have a decoder.
- Made the surrounding code more readable.
Note that the callback allows us to have a default fallback -
without having to check the CPU versions during the printout
itself. When an EDAC module registers itself, it can install the
decode-print function.
(there's no unregister needed as this is core code.)
version -v2 by Borislav Petkov:
- add K8 to the set of supported CPUs
- always build in edac_mce_amd since we use an early_initcall now
- fix checkpatch warnings

Don't pass the advanced position to strlcat() but just gives the buffer
head position so that the max size limit can be checked correctly.
Introduced a new helper function to standaralize strlcat() calls.

Since the SND_SOC_DAPM_LINE can be input or output, additional check is
needed in order to determine if the widget is connected as input or
output.
When checking for connected outputs, if the widget is line, than check
if the sources list is not empty (line is connected as output)
For input endpoint check, when the widget is line, also check if the
sinks list is not empty (line is connected as input).

The remove callback has to be marked as __devexit, as the dynamic unbind

The auto-parser for ALC662/663/272 codecs doesn't work properly when
a speaker is connected to mono NID 0x17, and doesn't handle the dynamic
DAC assignment properly.
This patch fixes the issues and also improves the assignment of DACs
so that HP and speakers can have independent volume controls.

On Soundblaster X-FI Titenium with emu20k2 the SIDE and SURROUND mute
functions are swapped.
It was checked with 'speaker-test -c 8 -s 3' and (un)mute surround or
'speaker-test -c 8 -s 7' and (un)mute side. The volume seems not
to be affected and works as expected.

When acceleration doesn't work we should free associated memory
and stop GPU block responsible for hardware acceleration so we
don't waste resource or let think one component of the driver that
a GPU feature is working/running while it doesn't actualy work.
