simple_prepare_write leaks uninitialised kernel data. This happens because
the it leaves an uninitialised "hole" over the part of the page that the
write is expected to go to. This is fine, but it then marks the page
uptodate, which means a concurrent read can come in and copy the
uninitialised memory into userspace before it written to.
Fix it by simply marking it uptodate in simple_commit_write instead, after
the hole has been filled in. This could theoretically break an fs that
uses simple_prepare_write and not simple_commit_write, and that relies on
the incorrect simple_prepare_write behaviour. Luckily, none of those
exists in the tree.

While cacheing is generally frowned upon in the 9p world, it has its
place -- particularly in situations where the remote file system is
exclusive and/or read-only. The vacfs views of venti content addressable
store are a real-world instance of such a situation. To facilitate higher
performance for these workloads (and eventually use the fscache patches),
we have enabled a "loose" cache mode which does not attempt to maintain
any form of consistency on the page-cache or dcache. This results in over
two orders of magnitude performance improvement for cacheable block reads
in the Bonnie benchmark. The more aggressive use of the dcache also seems
to improve metadata operational performance.

Driver model updates for the I2C core:
- Add new suspend(), resume(), and shutdown() methods. Use them in the
standard driver model style; document them.
- Minor doc updates to highlight zero-initialized fields in drivers, and
the driver model accessors for "clientdata".
If any i2c drivers were previously using the old suspend/resume calls
in "struct driver", they were getting warning messages ... and will
now no longer work. Other than that, this patch changes no behaviors;
and it lets I2C drivers use conventional PM and shutdown support.

These series of patches add UFS2 write-support. UFS2 - is default file system
for recent versions of FreeBSD.
The main differences from UFS1 from write support point of view
are:
1)Not all inodes are allocated during formatation of disk.
2)All meta-data(pointer to data blocks) are 64bit(in UFS1 they
are 32bit).
So patch series consist of
1)make possible mount UFS2 in read-write mode
2)code to write ufs2 inodes and code to initialize inodes chunks.
3)work with 64bit meta-data
I made simple testing like create/deleting/writing/reading/truncating, also I
ran fsx-linux and untar and build kernel on UFS1 and UFS2, after that FreeBSD
fsck do not find any errors in fs.
This patch makes possible to mount ufs2 "rw", and updates UFS2 documentation:

This defines a simple and minimalist programming interface for GPIO APIs:
- Documentation/gpio.txt ... describes things (read it)
- include/asm-arm/gpio.h ... defines the ARM hook, which just punts
to <asm/arch/gpio.h> for any implementation
- include/asm-generic/gpio.h ... implement "can sleep" variants as calling
the normal ones, for systems that don't handle i2c expanders.
The immediate need for such a cross-architecture API convention is to support
drivers that work the same on AT91 ARM and AVR32 AP7000 chips, which embed many
of the same controllers but have different CPUs. However, several other users
have been reported, including a driver for a hardware watchdog chip and some
handhelds.org multi-CPU button drivers.

This is an attempt of providing an interface for memory scrubbing control in
EDAC.
This patch modifies the EDAC Core to provide the Interface for memory
controller modules to implment.
The following things are still outstanding:
- K8 is the first implemenation,
The patch provide a method of configuring the K8 hardware memory scrubber
via the 'mcX' sysfs directory. There should be some fallback to a generic
scrubber implemented in software if the hardware does not support
scrubbing.
Or .. the scrubbing sysfs entry should not be visible at all.
- Only works with SDRAM, not cache,
The K8 can scrub cache and l2cache also - but I think this is not so
useful as the cache is busy all the time (one hopes).
One would also expect that cache scrubbing requires hardware support.
- Error Handling,
I would like that errors are returned to the user in "terms of file
system".
- Presentation,
I chose Bandwidth in Bytes/Second as a representation of the scrubbing
rate for the following reasons:
I like that the sysfs entries are sort-of textual, related to something
that makes sense instead of magical values that must be looked up.
"My People" wants "% main memory scrubbed per hour" others prefer "%
memory bandwidth used" as representation, "bandwith used" makes it easy to
calculate both versions in one-liner scripts.
If one later wants to scrub cache, the scaling becomes wierd for K8
changing from "blocks of 64 byte memory" to "blocks of 64 cache lines" to
"blocks of 64 bit". Using "bandwidth used" makes sense in all three cases,
(I.M.O. anyway ;-).
- Discovery,
There is no way to discover the possible settings and what they do
without reading the code and the documentation.
*I* do not know how to make that work in a practical way.
- Bugs(??),
other tools can set invalid values in the memory scrub control register,
those will read back as '-1', requiring the user to reset the scrub rate.
This is how *I* think it should be.
- Afflicting other areas of code,
I made changes to edac_mc.c and edac_mc.h which will show up globally -
this is not nice, it would be better that the memory scrubbing fuctionality
and interface could be entirely contained within the memory controller it
applies to.

Mathieu originally needed to add this for tracing Xen, but it's something
that's needed for any application that can be tracing while cpus are added.
unplug isn't supported by this patch. The thought was that at minumum a new
buffer needs to be added when a cpu comes up, but it wasn't worth the effort
to remove buffers on cpu down since they'd be freed soon anyway when the
channel was closed.

Add retain_initrd option to control freeing of initrd memory after
extraction. By default, free memory as previously.
The first boot will need to hold a copy of the in memory fs for the second
boot. This image can be large (much larger than the kernel), hence we can
save time when the memory loader is slow. Also, it reduces the memory
footprint while extracting the first boot since you don't need another copy
of the fs.

Implement device resource management, in short, devres. A device
driver can allocate arbirary size of devres data which is associated
with a release function. On driver detach, release function is
invoked on the devres data, then, devres data is freed.
devreses are typed by associated release functions. Some devreses are
better represented by single instance of the type while others need
multiple instances sharing the same release function. Both usages are
supported.
devreses can be grouped using devres group such that a device driver
can easily release acquired resources halfway through initialization
or selectively release resources (e.g. resources for port 1 out of 4
ports).
This patch adds devres core including documentation and the following
managed interfaces.
* alloc/free : devm_kzalloc(), devm_kzfree()
* IO region : devm_request_region(), devm_release_region()
* IRQ : devm_request_irq(), devm_free_irq()
* DMA : dmam_alloc_coherent(), dmam_free_coherent(),
dmam_declare_coherent_memory(), dmam_pool_create(),
dmam_pool_destroy()
* PCI : pcim_enable_device(), pcim_pin_device(), pci_is_managed()
* iomap : devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(),
devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(),

This patch adds a new, "binary" API in addition to the old, text API usbmon
had before. The new API allows for less CPU use, and it allows to capture
all data from a packet where old API only captured 32 bytes at most. There
are some limitations and conditions to this, e.g. in case someone constructs
a URB with 1GB of data, it's not likely to be captured, because even the
huge buffers of the new reader are finite. Nonetheless, I expect this new
capability to capture all data for all real life scenarios.
The downside is, a special user mode application is required where cat(1)
worked before. I have sample code at http://people.redhat.com/zaitcev/linux/
and Paolo Abeni is working on patching libpcap.
This patch was initially written by Paolo and later I tweaked it, and
we had a little back-and-forth. So this is a jointly authored patch, but
I am submitting this I am responsible for the bugs.

Change SysRq showBlockedTasks from sysrq-X to sysrq-W and show that in the
Help message.
It was previously done via X, but X is already used for Xmon on ppc & powerpc
platforms and this collision needs to be avoided.
All callers of register_sysrq_key() are now marked in the sysrq op/key table.
I didn't mark 'h' as Help because Help is just printed for any unknown key,
such as '?'.

NFS: Fix race in nfs_release_page()
invalidate_inode_pages2() may find the dirty bit has been set on a page
owing to the fact that the page may still be mapped after it was locked.
Only after the call to unmap_mapping_range() are we sure that the page
can no longer be dirtied.
In order to fix this, NFS has hooked the releasepage() method and tries
to write the page out between the call to unmap_mapping_range() and the
call to remove_mapping(). This, however leads to deadlocks in the page
reclaim code, where the page may be locked without holding a reference
to the inode or dentry.
Fix is to add a new address_space_operation, launder_page(), which will
attempt to write out a dirty page without releasing the page lock.

This reverts commit b026872601, which has
been linked to several problem reports with IO-APIC and the timer.
Machines either don't boot because the timer doesn't happen, or we get
double timer interrupts because we end up double-routing the timer irq
through multiple interfaces.
See for example

about some of the discussion.
Patches to fix this cleanup exist (and have been confirmed to work fine
at least for some of the affected cases) and we'll revisit it for
2.6.21, but this late in the -rc series we're better off just reverting
the incomplete commit that caused the problems.

Since get_user_pages() may be used with processes other than the
current process and calls flush_anon_page(), flush_anon_page() has to
cope in some way with non-current processes.
It may not be appropriate, or even desirable to flush a region of
virtual memory cache in the current process when that is different to
the process that we want the flush to occur for.
Therefore, pass the vma into flush_anon_page() so that the architecture
can work out whether the 'vmaddr' is for the current process or not.

...
Certain boards seem to like to issue false overcurrent notifications,
for example on ports that don't have anything connected to them. This
looks like a hardware error, at the level of noise to those ports'
overcurrent input signals (or non-debounced VBUS comparators). This
surfaces to users as truly massive amounts of syslog spam from khubd
(which is appropriate for real hardware problems, except for the
volume from multiple ports).
Using this new "ignore_oc" flag helps such systems work more sanely,
by preventing such indications from getting to khubd (and spamming
syslog). The downside is of course that true overcurrent errors will
be masked; they'll appear as spontaneous disconnects, without the
diagnostics that will let users troubleshoot issues like
short-circuited cables. In addition, controllers with no devices
attached will be forced to poll for new devices rather than relying on
interrupts, since each overcurrent event would generate a new
interrupt.
This patch (as826) is essentially a copy of David Brownell's ignore_oc
patch for ehci-hcd, ported to uhci-hcd.

Add support for the Fintek F71872F/FG Super-I/O chip. It is basically the
same as the Fintek F71805F/FG as far as hardware monitoring is concerned,
with two additional internal voltages monitored (VSB and battery), and 6
VID inputs (not yet supported.)
To make things a bit more confusing, two of the voltage input pins (in4
and in8) can be used for other functions. The driver reads the pin
configuration from the Super-I/O configuration space to decide whether
it must create interface files for these inputs or not.

Summary of changes:
- fixes:
o legacy I/O region size is 64 bytes, not 8 bytes
- general cleanup:
o removed code for the unsupported I2C block data, block data,
proc call and block proc call transfer modes
o removed detail warnings about unsupported modes that are
covered in a general warning (unsupported transaction...)
anyway
o removed necessity of a definition of struct i2c_adapter
o moved definition of struct i2c_algorithm, making forward
declarations of nforce2_access and nforce2_func unnecessary
- minor changes:
o in the description mention the nForce 5xx chipsets
o changes my e-mail address in MODULE_AUTHOR
Theses cleanups shrink the driver binary size from 4.0 kB to 2.7 kB
on i386.

Stabilize PIO mode transfers against a range of word sizes and FIFO
thresholds and fixes word size setup/override issues.
1) 16 and 32 bit DMA/PIO transfers broken due to timing differences.
2) Potential for bad transfer counts due to transfer size assumptions.
3) Setup function broken is multiple ways.
4) Per transfer bit_per_word changes break DMA setup in pump_tranfers.
5) False positive timeout are not errors.
6) Changes in pxa2xx_spi_chip not effective in calls to setup.
7) Timeout scaling wrong for PXA255 NSSP.
8) Driver leaks memory while busy during unloading.
Known issues:
SPI_CS_HIGH and SPI_LSB_FIRST settings in struct spi_device are not handled.
Testing:
This patch has been test against the "random length, random bits/word,
random data (verified on loopback) and stepped baud rate by octaves
(3.6MHz to 115kHz)" test. It is robust in PIO mode, using any
combination of tx and rx thresholds, and also in DMA mode (which
internally computes the thresholds).
Much thanks to Ned Forrester for exhaustive reviews, fixes and testing.
The driver is substantially better for his efforts.

The VIDEO_ZR36120 driver has:
- already been marked as BROKEN in 2.6.0 three years ago and
- is still marked as BROKEN.
Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.
But if anyone wants to ever revive this driver, the code is still
present in the older kernel releases.

This patch provides stacktrace filtering feature.
The stacktrace filter allows failing only for the caller you are
interested in.
For example someone may want to inject kmalloc() failures into
only e100 module. they want to inject not only direct kmalloc() call,
but also indirect allocation, too.
- e100_poll --> netif_receive_skb --> packet_rcv_spkt --> skb_clone
--> kmem_cache_alloc
This patch enables to detect function calls like this by stacktrace
and inject failures. The script Documentaion/fault-injection/failmodule.sh
helps it.
The range of text section of loaded e100 is expected to be
[/sys/module/e100/sections/.text, /sys/module/e100/sections/.exit.text)
So failmodule.sh stores these values into /debug/failslab/address-start
and /debug/failslab/address-end. The maximum stacktrace depth is specified
by /debug/failslab/stacktrace-depth.
Please see the example that demonstrates how to inject slab allocation
failures only for a specific module
in Documentation/fault-injection/fault-injection.txt

This patch provides fault-injection capability for kmalloc.
Boot option:
failslab=<interval>,<probability>,<space>,<times>
<interval> -- specifies the interval of failures.
<probability> -- specifies how often it should fail in percent.
<space> -- specifies the size of free space where memory can be
allocated safely in bytes.
<times> -- specifies how many times failures may happen at most.
Debugfs:
/debug/failslab/interval
/debug/failslab/probability
/debug/failslab/specifies
/debug/failslab/times
/debug/failslab/ignore-gfp-highmem
/debug/failslab/ignore-gfp-wait
Example:
failslab=10,100,0,-1
slab allocation (kmalloc(), kmem_cache_alloc(),..) fails once per 10 times.

This patch set provides some fault-injection capabilities.
- kmalloc() failures
- alloc_pages() failures
- disk IO errors
We can see what really happens if those failures happen.
In order to enable these fault-injection capabilities:
1. Enable relevant config options (CONFIG_FAILSLAB, CONFIG_PAGE_ALLOC,
CONFIG_MAKE_REQUEST) and if you want to configure them via debugfs,
enable CONFIG_FAULT_INJECTION_DEBUG_FS.
2. Build and boot with this kernel
3. Configure fault-injection capabilities behavior by boot option or debugfs
- Boot option
failslab=
fail_page_alloc=
fail_make_request=
- Debugfs
/debug/failslab/*
/debug/fail_page_alloc/*
/debug/fail_make_request/*
Please refer to the Documentation/fault-injection/fault-injection.txt
for details.

There is no manpower available to reform oui.db into a library for use
in more kernel subsystems. The low ratio of usefulness to size and the
