Now that ide-floppy supports SG_IO we can add support for SCSI ioctls
(except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET
ones - we can add them later iff really needed).
While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from
generic_ide_ioctl():
- This prevents ide-{disk,tape,scsi} device drivers from obtaining
REQ_TYPE_BLOCK_PC type requests which are currently unsupported by
these drivers and which are potentially harmful (as reported by Andrew).
- There is no functionality loss since aforementioned ioctls will now be
handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using
ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl()
(for devices using ide-cd driver).

The driver used to depend on BIOS settings for deciding whether it is OK
to use DMA. However it seems that BIOS doesn't always handle all cases
correctly so just let IDE core to decide about this. It should be a safe

Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of
the cmpxchg64b feature and enables compilation of the set_64bit() family.
Since the option is dependent on PAE, and since KVM depends on set_64bit(),
this effectively disables KVM on i386 nopae.
Simplify by removing the config option altogether: the boot check is made
dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed
without constraints. It is up to users to check for the feature flag (KVM
does not as virtualiation extensions imply its existence).

We have the following naming convention documented in
Documentation/hwmon/sysfs-interface for fault files:
in[0-*]_input_fault
fan[1-*]_input_fault
temp[1-*]_input_fault
Some drivers follow this convention (lm63, lm83, lm90, smsc47m192).
However some drivers omit the "input" part and create files named
fan1_fault (pc87427) or temp1_fault (dme1737). And the new "generic"
libsensors follows this second (non-standard) convention, so it fails
to report fault conditions for drivers which follow the standard.

shorter variant, so let's go for it.

ide-disk calls
ide_end_request(drive, 0, 0);
to finish an unknown request, but this doesn't work so well for non-fs
requests, since ide_end_request() internally looks at ->hard_cur_sectors
to see how much data to end. Only file system requests store a transfer
value in there, pc requests fill out ->data_len as a byte based transfer
value instead.
Since we ask to end 0 bytes of that request, it will never be terminated
and ide-disk gets stuck in a loop "handling" that same request over and
over.
Switch __ide_end_request() to take a byte based transfer count, and
adjust ide_end_request() to look at the right field to determine how
much IO to end when it's being passed in 0.

Some simple fixes to properly reference counter values from the block

was added, resulting in correct identification of block level attributes from

Added more verbose debug statement for event tracking.
Also during some corner testing, found a bug in the store/show sequence
of operations for the block attribute/controls management.
An old intermediate structure for 'blocks' was still in the processing
pipeline. This patch removes that old structure and correctly utilizes the
new struct edac_dev_sysfs_block_attribute for passing control from the sysfs
to the low level store/show function of the edac driver.
Now the proper kobj pointer to passed downward to the store/show

This patch refactors the 'releasing' of kobjects for the edac_mc type of
device. The correct pattern of kobject release is followed.
As internal kobjs are allocated they bump a ref count on the top level kobj.
It in turn has a module ref count on the edac_core module. When internal
kobjects are released, they dec the ref count on the top level kobj. When the
top level kobj reaches zero, it decrements the ref count on the edac_core
object, allow it to be unloaded, as all resources have all now been released.

This patch fixes and enhances the driver level set of sysfs attributes that
can be added to the 'block' level of an edac_device type of driver.
There is a controller information structure, which contains one or more
instances of device. Each instance will have one or more blocks of device
specific counters. This patch fixes the ability to have more detailed
attributes/controls for each of the 'blocks', providing for the addition of
controls/attributes from the low level driver to user space via sysfs.

If ERRSTS indicates that there's no error then we don't need to bother reading
the other registers.
In addition to making the common case faster, this actually fixes a small race
where we don't see an error but we clear the error bits anyway, potentially
wiping away info on an error that happened in the interim (or where a CE
arrives between the first and second read of ERRSTS, causing us to falsely
claim "UE overwrote CE").

This patch adds the new 'class' of object to be managed, named: 'edac_device'.
As a peer of the 'edac_mc' class of object, it provides a non-memory centric
view of an ERROR DETECTING device in hardware. It provides a sysfs interface
and an abstraction for varioius EDAC type devices.
Multiple 'instances' within the class are possible, with each 'instance'
able to have multiple 'blocks', and each 'block' having 'attributes'.
At the 'block' level there are the 'ce_count' and 'ue_count' fields
which the device driver can update and/or call edac_device_handle_XX()
functions. At each higher level are additional 'total' count fields,
which are a summation of counts below that level.
This 'edac_device' has been used to capture and present ECC errors
which are found in a a L1 and L2 system on a per CORE/CPU basis.

This is a large patch to refactor the original EDAC module in the kernel
and to break it up into better file granularity, such that each source
file contains a given subsystem of the EDAC CORE.
Originally, the EDAC 'core' was contained in one source file: edac_mc.c
with it corresponding edac_mc.h file.
Now, there are the following files:
edac_module.c The main module init/exit function and other overhead
edac_mc.c Code handling the edac_mc class of object
edac_mc_sysfs.c Code handling for sysfs presentation
edac_pci_sysfs.c Code handling for PCI sysfs presentation
edac_core.h CORE .h include file for 'edac_mc' and 'edac_device' drivers
edac_module.h Internal CORE .h include file
This forms a foundation upon which a later patch can create the 'edac_device'
class of object code in a new file 'edac_device.c'.

lguest is a simple hypervisor for Linux on Linux. Unlike kvm it doesn't need
VT/SVM hardware. Unlike Xen it's simply "modprobe and go". Unlike both, it's
5000 lines and self-contained.
Performance is ok, but not great (-30% on kernel compile). But given its
hackability, I expect this to improve, along with the paravirt_ops code which
it supplies a complete example for. There's also a 64-bit version being
worked on and other craziness.
But most of all, lguest is awesome fun! Too much of the kernel is a big ball
of hair. lguest is simple enough to dive into and hack, plus has some warts
which scream "fork me!".

Introduce the pm_power_off_prepare() callback that can be registered by the
interested platforms in analogy with pm_idle() and pm_power_off(), used for
preparing the system to power off (needed by ACPI).
This allows us to drop acpi_sysclass and device_acpi that are only defined in
order to register the ACPI power off preparation callback, which is needed by
pm_power_off() registered in a much different way.

Since we are now explicitly calling hibernation_ops->prepare() before

At least on some machines it is necessary to prepare the ACPI firmware for the
restoration of the system memory state from the hibernation image if the
"platform" mode of hibernation has been used. Namely, in that cases we need
to disable the GPEs before replacing the "boot" kernel with the "frozen"
kernel (cf. http://bugzilla.kernel.org/show_bug.cgi?id=7887). After the
restore they will be re-enabled by hibernation_ops->finish(), but if the
restore fails, they have to be re-enabled by the restore code explicitly.
For this purpose we can introduce two additional hibernation operations,
called pre_restore() and restore_cleanup() and call them from the restore code
path. Still, they should be called if the "platform" mode of hibernation has
been used, so we need to pass the information about the hibernation mode from
the "frozen" kernel to the "boot" kernel in the image header.
Apparently, we can't drop the disabling of GPEs before the restore because of
Bug #7887 . We also can't do it unconditionally, because the GPEs wouldn't
have been enabled after a successful restore if the suspend had been done in
the 'shutdown' or 'reboot' mode.
In principle we could (and probably should) unconditionally disable the GPEs
before each snapshot creation *and* before the restore, but then we'd have to
unconditionally enable them after the snapshot creation as well as after the
restore (or restore failure) Still, for this purpose we'd need to modify
acpi_enter_sleep_state_prep() and acpi_leave_sleep_state() and we'd have to
introduce some mechanism synchronizing the disablind/enabling of the GPEs with
the device drivers' .suspend()/.resume() routines and with
disable_/enable_nonboot_cpus(). However, this would have affected the
suspend (ie. s2ram) code as well as the hibernation, which I'd like to avoid
in this patch series.

Tina Yang <tina.yang@oracle.com> discovered an MSI related problem
when doing kdump. The problem is that the kexec kernel is booted
without going through system reset, and as a result, MSI may already
be enabled when tg3_init_one() is called. tg3_init_one() calls
pci_save_state() which will save the stale MSI state. Later on in
tg3_open(), we call pci_enable_msi() to reconfigure MSI on the chip
before we reset the chip. After chip reset, we call
pci_restore_state() which will put the stale MSI address/data back
onto the chip.
This is no longer a problem in the latest kernel because
pci_restore_state() has been changed to restore MSI state from
internal data structures which will guarantee restoring the proper
MSI state.
But I think we should still fix it. Our save and restore sequence
can still cause very subtle problems down the road. The fix is to
have our own functions save and restore precisely what we need. We
also change it to save and restore state inside tg3_chip_reset() in a
more straight forward way.
Thanks to Tina for helping to test and debug the problem.

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.

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.

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.

Coverity (1792) spotted a possibly uninitialized return value in case of

1117 struct IsdnCardState *cs)
1119 int ret;

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.

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.
