In order to enable things like PM_TRACE, you're required to enable
PM_DEBUG, which sends a large spew of messages on boot, and often times can
overflow dmesg buffer.
Create new PM_VERBOSE and shift that to be the option that enables
drivers/base/power's messages.

ISDN HiSax: uninitialized return in hisax_cs_setup

Coverity (1792) spotted a possibly uninitialized return value in case of
kmalloc() failure:
1116 static int hisax_cs_setup(int cardnr, struct IsdnCard *card,
1117 struct IsdnCardState *cs)
1119 int ret;
1120
1121 if (!(cs->rcvbuf = kmalloc(MAX_DFRAME_LEN_L1, GFP_ATOMIC))) {
1122 printk(KERN_WARNING "HiSax: No memory for isac rcvbuf\n");
1123 ll_unload(cs);
1124 goto outf_cs;
...
1165 outf_cs:
1166 kfree(cs);
1167 card->cs = NULL;
1168 return ret;
The straightforward solution would be to just add the missing
initialization but hardcoding the return value in the out_cs branch
(only taken on failure) seems to work just as well and it allows killing
a couple of other lines too.

The driver didn't allow an interface's MAC address to be modified if the
respective interface wasn't setup - a failing Hcall was the result. Thus
bonding wasn't usable. The fix moves the failing Hcall which was registering
a MAC address for the reception of BC packets in firmware from the port up
and down functions to the port resources setup functions. Additionally the
missing update of the last_rx member of the netdev structure was added.

The TSEC/eTSEC can detect the interface to the PHY automatically,
but it isn't able to detect whether the RGMII connection needs internal
delay. So we need to detect that change in the device tree, propagate
it to the platform data, and then check it if we're in RGMII. This fixes
a bug on the 8641D HPCN board where the Vitesse PHY doesn't use the delay
for RGMII.

The Vitesse 824x PHY doesn't allow an interrupt to be cleared if
the mask bit for that interrupt isn't set. This means that the PHY
Lib's order of handling interrupts (disable, then clear) breaks on this
PHY. However, clearing then disabling the interrupt opens up the code
for a silly race condition. So rather than change the PHY Lib, we change
the Vitesse driver so it always clears interrupts before disabling them.
Further, the ack function only clears the interrupt if interrupts are
enabled.

This defines a dev_vdbg() call, which is enabled with -DVERBOSE_DEBUG.
When enabled, dev_vdbg() acts just like dev_dbg(). When disabled, it is a
NOP ... just like dev_dbg() without -DDEBUG. The specific code was moved
out of a USB patch, but lots of drivers have similar support.
That is, code can now be written to use an additional level of debug
output, selected at compile time. Many driver authors have found this
idiom to be very useful. A typical usage model is for "normal" debug
messages to focus on fault paths and not be very "chatty", so that those
messages can be left on during normal operation without much of a
performance or syslog load. On the other hand "verbose" messages would be
noisy enough that they wouldn't normally be enabled; they might even affect
timings enough to change system or driver behavior.

this is a patch that adds support for Hilscher CIF DeviceNet and
Profibus cards. I tested it on a Kontron CPX board, and Thomas reviewed
it.
You can find the user space part here:
http://www.osadl.org/projects/downloads/UIO/user/cif-0.1.0.tar.gz
Notes: cif_api.c is the main file you want to look at. It contains the
functions to open, close, mmap and so on. cif_dps.c adds functions
specific to Profibus cards, and cif_dn.c contains functions for
DeviceNet cards. cif.c is a universal playground, it's just a small
test program. The user space part of this UIO driver is still work in
progress, and not everything is tested yet. At the moment, the thread in
cif_api.c contains some code that artificially makes the card generate
interrupts, this was added for testing and will be removed later. But
the driver already contains all the functions needed for useful
operation, so it gives a good idea of how such a thing looks like.
For comparison, here's what you get from the manufacturer
(www.hilscher.com) when you ask for a Linux 2.6 driver:

This interface allows the ability to write the majority of a driver in
userspace with only a very small shell of a driver in the kernel itself.
It uses a char device and sysfs to interact with a userspace process to
process interrupts and control memory accesses.
See the docbook documentation for more details on how to use this
interface.

Current code sets size0 to 0 at the start of work request posting
functions and then handles size0 == 0 specially within the loop over
work requests. Change this so size0 is set along with f0 the first
time through the loop (when nreq == 0). This makes the code easier to
understand by making it clearer that f0 and size0 are always
initialized if nreq != 0 without having to know that size0 == 0
implies nreq == 0.
Also annotate size0 with uninitialized_var() so that this doesn't
introduce a new compiler warning.

Factor code to set data segment entries out of the work request
posting functions into inline functions mthca_set_data_seg() and
mthca_set_data_seg_inval(). This makes the code more readable and
also allows the compiler to do a better job -- on x86_64:

Return the receive queue sizes for both userspace QPs and kernel Qps
(not just kernel QPs) from mlx4_ib_query_qp(). Also zero the send
queue sizes for userspace QPs to avoid a possible information leak,
and set the max_inline_data for kernel QPs to 0 since inline sends are
not supported for kernel QPs.

Change the maximum number of outstanding RDMA reads allowed as a
target from 4 to 16 to per QP. This allows RDMA read operations to
pipeline better.

Local write permission makes no sense as part of the QP access flags,
since the access flags only control what the remote end of the
connection is allowed to do. Remove the code in the RDMA CM that
initializes qp_access_flags with IB_ACCESS_LOCAL_WRITE.

Commit 9db48926 ("drivers/infiniband/hw/mthca/mthca_qp: kill uninit'd
var warning") added "= 0" to the declarations of f0 to shut up gcc
warnings. However, there's no point in making the code bigger by
initializing f0 to a random value just to get rid of a warning;
setting f0 to 0 is no safer than just using uninitialized_var(), which
documents the situation better and gives smaller code too. For example,
on x86_64:
add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-16 (-16)
function old new delta
mthca_tavor_post_send 1352 1344 -8

Reset the device when an internal error is detected.
Also, detect errors by polling the error buffer rather than using
interrupts. This is more robust and doesn't depend on MSI-X. Remove
the old interrupt handler entirely, since we don't want to support two
mechanisms for detecting internal errors.

When warning about out-of-date firmware, current mthca code messes up
the formatting of the version if the subminor doesn't have three
digits. It doesn't fill the field with 0s so we end up with:
ib_mthca 0000:0b:00.0: HCA FW version 1.1. 0 is old (1.2. 0 is current).
Change the format from "%3d" to "%03d" to get the right thing printed.

The mthca driver supports both MSI and MSI-X. However, MSI-X works with
all hardware that the driver handles, and provides a superset of what
MSI does, so there's no point in having code for both. Schedule MSI
support for removal in 2008 to give anyone who actually needs MSI and
who can't use MSI time to speak up.
