Converting page lock to new locking bitops requires a change of page flag
operation naming, so we might as well convert it to something nicer
(!TestSetPageLocked_Lock => trylock_page, SetPageLocked => set_page_locked).
This also facilitates lockdeping of page lock.

2.6.26 corrected the mutex locking on tty resizing to fix the case where

For some time my at91sam9260 board with JFFS2 on serial flash (m25p80)
would hang when accessing the serial flash and SPI bus. Slowing the SPI
clock down to 9 MHz reduced the occurrence of the hang from "always"
during boot to a nuisance level that allowed other SW development to
continue. Finally had to address this issue when an application stresses
the I/O to always cause a hang.
Hang seems to be caused by a missed SPI interrupt, so that the task ends
up waiting forever after calling spi_sync(). The fix has 2 parts. First
is to halt the DMA engine before the "current" PDC registers are loaded.
This ensures that the "next" registers are loaded before the DMA operation
takes off. The second part of the fix is a kludge that adds a
"completion" interrupt in case the ENDRX interrupt for the last segment of
the DMA chaining operation was missed.
The patch allows the SPI clock for the serial flash to be increased from 9
MHz to 15 MHz (or more?). No hangs or SPI overruns were encountered.
Haavard: while this patch does indeed improve things, I still see overruns
and CRC errors on my NGW100 board when running the DataFlash at 10 MHz.
However, I think some improvement is better than nothing, so I'm passing
this on for inclusion in 2.6.27.

Having the buffer on the stack and even re-using it for all led devices is bad.
Not being able to resolve the name member of the led device structure to a
meaningful value leads to confusion during ad-hoc debugging and potential
breakage in the future, if we ever decide to access the name member outside of
the registration function. Move the buffer to our private per led device
structures so that it is accessible after registration.
A quick grep didn't yield any occurence of using the led device name parameter
outside of the led device registration function, so currently we should already
be safe for normal operation.

Running 'ifconfig up' on the cxgb3 interface with iw_cxgb3 loaded
causes a deadlock. The rtnl lock is already held in this path. The
function fw_supports_fastreg() was introduced in 2.6.27 to
conditionally set the IB_DEVICE_MEM_MGT_EXTENSIONS bit iff the
firmware was at 7.0 or greater, and this function also acquires the
rtnl lock and which thus causes a deadlock. Further, if iw_cxgb3 is
loaded _after_ the nic interface is brought up, then the deadlock does
not occur and therefore fw_supports_fastreg() does need to grab the
rtnl lock in that path.
It turns out this code is all useless anyway. The low level driver
will NOT allow the open if the firmware isn't 7.0, so iw_cxgb3 can
always set the MEM_MGT_EXTENSIONS bit. Simplify...

Recently, a bug having to do with the alignment of transaction response

presence of that bug in order to function correctly. In order to stay
compatible with old versions of those apps, this patch preserves the bug
in cases where it is harmless to normal operation (such as the single
quadlet read) due to a simple duplication of data. This guarantees
maximum compatability for those users who are using the old app with the

Each resource should be printed on its own line, so start snprintf'ing
at the beginning of the buffer every time through the loop.
Also, use scnprintf() rather than snprintf() when building up the
buffer to print. scnprintf() returns the number of characters actually
written into the buffer (not including the trailing NULL).
snprintf() returns the number of characters that *would be* written,
assuming everything would fit in the buffer. That's nice if we want to
resize the buffer to make sure everything fits, but in this case, I
just want to keep from overflowing the buffer, and it's OK if the
output is truncated.
Using snprintf() meant that my "len" could grow to be more than the
the buffer size, which makes "sizeof(buf) - len" negative, which causes
this alarming WARN_ON:

Some users of the RTL8187B have experienced difficulties since commit
49292d5635 that introduced the power
management wext hooks. This difficulty has not made much sense until
it was realized that it was possible for mac80211 to make a call to the
config routine while that routine was already being executed. On this
device, it is necessary to loopback the TX when changing channels. Unless
this is properly restored, the device will lockup. A mutex now protects
the device state, and the private data in several places.
The problem was found by Herton Ronaldo Krzesinski <herton@mandriva.com.br>,
who also suggested this type of fix.

In kernel version 2.6.26-rc9 my wireless LAN card worked; but in the
released 2.6.26, my RaLink rt2500 card wouldn't associate.
Git-bisect led me to this patch:
61486e0f68
rt2x00: Remove ieee80211_tx_control argument from write_tx_desc()
I believe that there is a problem with that patch --- it
(inadvertantly) removes an extra line of code, that used to set the
DATABYTE_COUNT field.
This patch reinstates that line, and with it my card works again.

More LM75 updates:
- Teach the LM75 driver to use new-style driver binding:
* Create a second driver struct, using new-style driver binding
methods cribbed from the legacy code.
* Add a MODULE_DEVICE_TABLE (for "newER-style binding")
* The legacy probe logic delegates its work to this new code.
* The legacy driver now uses the name "lm75_legacy".
- More careful initialization. Chips are put into 9-bit mode so
the current interconversion routines will never fail.
- Save the original chip configuration, and restore it on exit.
(Among other things, this normally turns off the mode where
the chip is constantly sampling ... and thus saves power.)
So the new-style code should catch all chips that boards declare,
while the legacy code catches others. This particular coexistence
strategy may need some work yet ... legacy modes might best be set
up explicitly by some tool not unlike "sensors-detect". (Or else
completely eradicated...)

Minor cleanup and reorg of the lm75 code.
- Kconfig provides a larger list of lm75-compatible chips
- A top comment now says what the driver does (!) ... as in, just
what sort of sensor is this??
- Section comments now delineate the various sections of the driver:
hwmon attributes, driver binding, register access, module glue.
One driver binding function moved out of the attribute section,
as did the driver struct itself.
- Minor tweaks to legacy probe logic: correct a comment, and
remove a pointless variable.
- Whitespace, linelength, and comment fixes.
This patch should include no functional changes. It's preparation
for adding new-style (driver model) I2C driver binding.

- Add support for the RDC 1010 variant
- Rework the core library to have a read_id method. This allows the hacky
bits of it821x to go and prepares us for pata_hd
- Switch from WARN to BUG in ata_id_string as it will reboot if you get
it wrong so WARN won't be seen
- Allow the issue of command 0xFC on the 821x. This is needed to query
rebuild status.
- Tidy up printk formatting
- Do more ident rewriting on RAID volumes to handle firmware provided
ident data which is rather wonky
- Report the firmware revision and device layout in RAID mode
- Don't try and disable raid on the 8211 or RDC - they don't have the
relevant bits

The ali_init_one() function does a search for an isa_bridge,
but then fails to release it if the revision information was
not correctly found.
the problem comes from:
isa_bridge = pci_get_device(...);
if (isa_bridge && ...) {
pci_dev_put(isa_bridge);
}
where the pci_dev_put() is never called if isa_bridge
was valid but the extra checks on the chip-revision

This series of patches adds a driver for the SGI UV GRU. The driver is
still in development but it currently compiles for both x86_64 & IA64.
All simple regression tests pass on IA64. Although features remain to be
added, I'd like to start the process of getting the driver into the
kernel. Additional kernel drivers will depend on services provide by the
GRU driver.
The GRU is a hardware resource located in the system chipset. The GRU
contains memory that is mmaped into the user address space. This memory
is used to communicate with the GRU to perform functions such as
load/store, scatter/gather, bcopy, AMOs, etc. The GRU is directly
accessed by user instructions using user virtual addresses. GRU
instructions (ex., bcopy) use user virtual addresses for operands.
The GRU contains a large TLB that is functionally very similar to
processor TLBs. Because the external contains a TLB with user virtual
address, it requires callouts from the core VM system when certain types
of changes are made to the process page tables. There are several MMUOPS
patches currently being discussed but none has been accepted into the
kernel. The GRU driver is built using version V18 from Andrea Arcangeli.
This patch:
Contains the definitions of the hardware GRU data structures that are used
by the driver to manage the GRU.

Solves http://bugzilla.kernel.org/show_bug.cgi?id=11127
The old rtc.c driver did it and some drivers (like rtc-sh) do it in their
release function, though they should not -- because they should provide
the irq_set_state op and the rtc framework itself should care about it.
This patch makes it do so.
I am aware that some drivers, like rtc-sh, handle userspace PIE sets in
their ioctl op (instead of having the framework call the op), exporting
the irq_set_state op at the same time. The logic in rtc_irq_set_state
should make sure it doesn't matter and the driver should not need to care
stopping periodic interrupts in its release routine any more.
The correct way, in my opinion, should be this:
1) The driver provides the irq_set_state op and does not care closing the
interrupts in its release op.
2) If the driver does not provide the op and handles PIE in the ioctl op, it's
reponsible for closing them in its release op.
3) Something similar for other IRQs, like UIE -- if there's no in-kernel API
like irq_set_state, handle it in ioctl and release ops. The framework will
be responsible either for everything or for nothing. (This will probably
change later.)

On HPPA there exists some older GSC graphics cards, which need special
graphic-card-BIOS patching to become supported. Since we don't have yet
implemented the patching, it's better to detect such cards in advance,
inform to the user that there are known problems and to not activate the
card.
Problematic GSC cards and BIOS versions are:
* Hyperdrive/Hyperbowl (A4071A) graphics card series:
* ID = 0x2BCB015A (Version 8.04/8)
* ID = 0x2BCB015A (Version 8.04/11)
* Thunder 1 VISUALIZE 48 card:
* ID = 0x2F23E5FC (Version 8.05/9)
* Thunder 2 VISUALIZE 48 XP card:
* ID = 0x2F8D570E (Version 8.05/12)
* Some Hyperion and ThunderHawk GSC cards

The wrong version of the "teach dataflash about binary density" patch
just got merged (v2 not v3) ... this restores the missing updates:
* Fix the cmdlinepart *regression* that caused testing failures (!!)
by restoring the original part labels in relevant cases.
* Don't reference things that don't exist (!)
- An opcode that doesn't even exist for DataFlash
- The part is "at45db642" not "at45db641"
- ID zero in this JEDEC table
* Make the JEDEC probe routine report and handle errors better:
- If the SPI calls fail, return the error codes.
- Don't depend on ordering of table entries.
- Unrecognized ids are different from parts that have no ID.
We won't actually know how to handle them correctly; display
the ID and ignore the chip.
* Move the original block comment about the "legacy" chip ID scheme
back next to the code to which it applies ... not next to the new
JEDEC query code, which uses an entirely different strategy.
* Don't print a guessed erasesize; /proc/mtd has the real value.

This adds the regulator framework core.
This framework is designed to provide a generic interface to voltage
and current regulators within the Linux kernel. It's intended to
provide voltage and current control to client or consumer drivers and
also provide status information to user space applications through a
sysfs interface.
The intention is to allow systems to dynamically control regulator
output in order to save power and prolong battery life. This applies
to both voltage regulators (where voltage output is controllable) and
current sinks (where current output is controllable).
This framework safely compiles out if not selected so that client
drivers can still be used in systems with no software controllable
regulators.

To do that, s2io_nic->stats turned into a staging area, where is saved

value that should be summed up, in order to get the correct statistics

not just falling edges. Similarly, other boards might route it

Wireless statistics produced by the RTL8187B driver are not particularly
informative about the strength of the received signal. From the data sheet
provided by Realtek, I discovered that certain parts of the RX header
should have the information necessary to calculate signal quality and
strength. With testing, it became clear that most of these quantities were
very jittery - only the AGC correlated with the signals expected from nearby
AP's. As a result, the quality and strength are derived from the agc value.
The scaling has been determined so that the numbers are close to those
obtained by b43 under the same conditions. The results are qualitatively
correct.
Statistics derived for the RTL8187 have not been changed.
The RX header variables have been renamed to match the quantites described
in the Realtek data sheet.

rt2x00 will only perform configuration changes from
mac80211 when the configuration option has changed.
This means it keeps track of the current active configuration
and will check these values when the config() callback function
is used.
However this causes breakage when the interface has been
brought down and up again, since all stored active values
aren't reset while the registers might have.
This is for example the case with rt61pci antenna registers which
will jump to invalid values when the interface has been started.
To make sure a full configuration takes place after the start()
callback function, a new flag is added which will be checked
during config() and skips the "what's changed" phase.

In rt2x00 the value was
( SIFS + (8 * (IEEE80211_HEADER + ACK_SIZE)) )
which comes down to 314us while the legacy driver uses the value 364us
This was caused because EIFS is: SIFS + DIFS + AckTime

entry in the list is self-linked, it overwrites the entry until we link
new buffers.
Ensure that we don't free this last one until we are 100% sure that it
is not used by the hardware anymore to not cause memory curruption as
can be seen below.
This is done by checking next buffer in the list. Even after that we
know that the hardware refetched the new link and proceeded further
(the next buffer is ready) we can finally free the overwritten buffer.
We discard it since the status in its descriptor is overwritten (OR-ed
by new status) too.

As noted by Manuel:
Commit c63847a362 ("sh: Add
SCIF2 support for SH7763.") broke build with CONFIG_EARLY_PRINTK
enabled for me (SH7760):
CC arch/sh/kernel/early_printk.o
/mnt/work/sh7760/kernel/linux-2.6.git/arch/sh/kernel/early_printk.c: In function 'scif_sercon_putc':
/mnt/work/sh7760/kernel/linux-2.6.git/arch/sh/kernel/early_printk.c:84: error: implicit declaration of function 'sci_SCFDR_in'
Move the SH7763 definitions out on their own, so they don't create additional
confusion within the SH7760/SH7780/SH7785 block. Restore the deleted
SCFDR definition for these parts.

This patch cleans up the handling of the maple bus queue to remove
the risk of races when adding packets. It also removes references to the
redundant connect and disconnect functions.
