The one thing which surprises me in this patch that cis->Length needs to be
set to count+1. Without it, it doesn't work, but with it, it doesn't make
sense to me.

Export information to /sbin/hotplug for PCMCIA devices: card_id, manf_id,
func_id, bus_id (like pcmcia1.0) and crc32-hashes of the prod_id strings.
Why not the prod_id strings themselves?
a) They may contain all sorts of strange and difficult to handle characters,
like " ".
b) It's impossible to pass multiple strings to userspace.

In -mm1 the cardbus resources might be assigned in
pci_assign_unassigned_resources() pass. From your dmesg:
PCI: Bus 2, cardbus bridge: 0000:00:0b.0

Then yenta_allocate_res() tries to assign these resources again and,
naturally, fails.
This adds check for already assigned cardbus resources.

git did actually warn me about the fact that I hadn't actually done an

a list of all the files that _did_ change in the merge, so I never

Old ISA/VESA systems sometimes put tertiary IDE controllers at addresses
0x1e8, 0x168, 0x1e0 or 0x160. Linux thus probes these addresses on x86
systems. Unfortunately some PCI systems now use these addresses for other
purposes which leads to users seeing minute plus hangs during boot or even
crashes.
The following patch (again has been in Fedora for a while) only probes the
obscure legacy ISA ports on machinea that are pre-PCI. This seems to keep
everyone happy and if there is someone with that utterly weird corner case
the ide= command line still provides a get out of jail card.
Unsurprisingly we've not found anyone so affected.

This lets you throw out the iteraid stuff that has ended up back in due
to stupid goings on in the IDE world. Its the same heavily tested code
shipped in Fedora/Red Hat products but without the other dependancies on
the Bartlomiej IDE layer.
Pre-requisite: the ide-disk patch I sent to handle pure LBA devices.
Obviously you lose things like hot unplug with the Bartlomiej IDE layer
at the moment but that won't matter to most users.
The patch does the following
- Add IT8211/12 to pci_ids.h
- Add Makefile/Kconfig entry
- Add it8212 driver

You can't install the base kernel on a Stratus box because of the overuse of
__init. Affects both IDE layers identically. It isn't the only misuser of
__init so more review of other drivers (or fixing ide_register code to know
about hotplug v non-hotplug chipsets) would be good.
Original issue found by Stratus and their patch was the inspiration for this
trivial one.

The ide-generic driver gives you DMA at bios tuned speed so can actually run a
lot of unsupported devices quite well. It has a pci table so that it doesn't
grab disks owned by other drivers but no way to override this. The patch adds
an option ide-generic-all which makes the driver grab everything going that is
IDE class.
The diff is messy because I put the special case as case 0 to make the if
conditional and long term maintenance easier.
This has been in Fedora for some time.

Without the ability to atomically write 16 bytes, we can not update the
middle slot of a bundle, slot 1, unless we stop the machine first. This
patch will ensure the ability to robustly insert and remove a kprobe by
refusing to insert a kprobe on slot 1 until a mechanism is in place to
safely handle this case.

The following is a patch provided by Ananth Mavinakayanahalli that implements
the new PPC64 specific parts of the new function return probe design.
NOTE: Since getting Ananth's patch, I changed trampoline_probe_handler()
to consume each of the outstanding return probem instances (feedback
on my original RFC after Ananth cut a patch), and also added the
arch_init() function (adding arch specific initialization.) I have
cross compiled but have not testing this on a PPC64 machine.
Changes include:
* Addition of kretprobe_trampoline to act as a dummy function for instrumented
functions to return to, and for the return probe infrastructure to place
a kprobe on on, gaining control so that the return probe handler
can be called, and so that the instruction pointer can be moved back
to the original return address.
* Addition of arch_init(), allowing a kprobe to be registered on
kretprobe_trampoline
* Addition of trampoline_probe_handler() which is used as the pre_handler
for the kprobe inserted on kretprobe_implementation. This is the function
that handles the details for calling the return probe handler function
and returning control back at the original return address
* Addition of arch_prepare_kretprobe() which is setup as the pre_handler
for a kprobe registered at the beginning of the target function by
kernel/kprobes.c so that a return probe instance can be setup when
a caller enters the target function. (A return probe instance contains
all the needed information for trampoline_probe_handler to do it's job.)
* Hooks added to the exit path of a task so that we can cleanup any left-over
return probe instances (i.e. if a task dies while inside a targeted function
then the return probe instance was reserved at the beginning of the function
but the function never returns so we need to mark the instance as unused.)

The following patch implements function return probes for ia64 using
the revised design. With this new design we no longer need to do some
of the odd hacks previous required on the last ia64 return probe port
that I sent out for comments.
Note that this new implementation still does not resolve the problem noted
by Keith Owens where backtrace data is lost after a return probe is hit.

The following patch contains the x86_64 specific changes for the new
return probe design. Changes include:
* Removing the architecture specific functions for querying a return probe
instance off a stack address
* Complete rework onf arch_prepare_kretprobe() and trampoline_probe_handler()
* Removing trampoline_post_handler()
* Adding arch_init() so that now we handle registering the return probe
trampoline instead of kernel/kprobes.c doing it
NOTE:
Note that with this new design, the dependency on calculating a pointer to
the task off the stack pointer no longer exist (resolving the problem of
interruption stacks as pointed out in the original feedback to this port.)

The following is the second version of the function return probe patches
I sent out earlier this week. Changes since my last submission include:
* Fix in ppc64 code removing an unneeded call to re-enable preemption
* Fix a build problem in ia64 when kprobes was turned off
* Added another BUG_ON check to each of the architecture trampoline
handlers
My initial patch description ==>
From my experiences with adding return probes to x86_64 and ia64, and the
feedback on LKML to those patches, I think we can simplify the design
for return probes.
The following patch tweaks the original design such that:
* Instead of storing the stack address in the return probe instance, the
task pointer is stored. This gives us all we need in order to:
- find the correct return probe instance when we enter the trampoline
(even if we are recursing)
- find all left-over return probe instances when the task is going away
This has the side effect of simplifying the implementation since more
work can be done in kernel/kprobes.c since architecture specific knowledge
of the stack layout is no longer required. Specifically, we no longer have:
- arch_get_kprobe_task()
- arch_kprobe_flush_task()
- get_rp_inst_tsk()
- get_rp_inst()
- trampoline_post_handler() <see next bullet>
* Instead of splitting the return probe handling and cleanup logic across
the pre and post trampoline handlers, all the work is pushed into the
pre function (trampoline_probe_handler), and then we skip single stepping
the original function. In this case the original instruction to be single
stepped was just a NOP, and we can do without the extra interruption.
The new flow of events to having a return probe handler execute when a target
function exits is:
* At system initialization time, a kprobe is inserted at the beginning of
kretprobe_trampoline. kernel/kprobes.c use to handle this on it's own,
but ia64 needed to do this a little differently (i.e. a function pointer
is really a pointer to a structure containing the instruction pointer and
a global pointer), so I added the notion of arch_init(), so that
kernel/kprobes.c:init_kprobes() now allows architecture specific
initialization by calling arch_init() before exiting. Each architecture
now registers a kprobe on it's own trampoline function.
* register_kretprobe() will insert a kprobe at the beginning of the targeted
function with the kprobe pre_handler set to arch_prepare_kretprobe
(still no change)
* When the target function is entered, the kprobe is fired, calling
arch_prepare_kretprobe (still no change)
* In arch_prepare_kretprobe() we try to get a free instance and if one is
available then we fill out the instance with a pointer to the return probe,
the original return address, and a pointer to the task structure (instead
of the stack address.) Just like before we change the return address
to the trampoline function and mark the instance as used.
If multiple return probes are registered for a given target function,
then arch_prepare_kretprobe() will get called multiple times for the same
task (since our kprobe implementation is able to handle multiple kprobes
at the same address.) Past the first call to arch_prepare_kretprobe,
we end up with the original address stored in the return probe instance
pointing to our trampoline function. (This is a significant difference
from the original arch_prepare_kretprobe design.)
* Target function executes like normal and then returns to kretprobe_trampoline.
* kprobe inserted on the first instruction of kretprobe_trampoline is fired
and calls trampoline_probe_handler() (no change here)
* trampoline_probe_handler() consumes each of the instances associated with
the current task by calling the registered handler function and marking
the instance as unused until an instance is found that has a return address
different then the trampoline function.
(change similar to my previous ia64 RFC)
* If the task is killed with some left-over return probe instances (meaning
that a target function was entered, but never returned), then we just
free any instances associated with the task. (Not much different other
then we can handle this without calling architecture specific functions.)
There is a known problem that this patch does not yet solve where
registering a return probe flush_old_exec or flush_thread will put us
in a bad state. Most likely the best way to handle this is to not allow
registering return probes on these two functions.
(Significant change)
This patch series applies to the 2.6.12-rc6-mm1 kernel, and provides:
* kernel/kprobes.c changes
* i386 patch of existing return probes implementation
* x86_64 patch of existing return probe implementation
* ia64 implementation
* ppc64 implementation (provided by Ananth)
This patch implements the architecture independant changes for a reworking
of the kprobes based function return probes design. Changes include:
* Removing functions for querying a return probe instance off a stack address
* Removing the stack_addr field from the kretprobe_instance definition,
and adding a task pointer
* Adding architecture specific initialization via arch_init()
* Removing extern definitions for the architecture trampoline functions
(this isn't needed anymore since the architecture handles the
initialization of the kprobe in the return probe trampoline function.)

Now that PPC64 has no-execute support, here is a second try to fix the
single step out of line during kprobe execution. Kprobes on x86_64 already
solved this problem by allocating an executable page and using it as the
scratch area for stepping out of line. Reuse that.

This patch started life as as527, and was rediffed by me.
Since the IDE interface doesn't convey much information about types of
errors, many USB-IDE adapters report all low-level errors with SK = 0x04,
which is supposed to be used only for non-recoverable errors. As a result
the SCSI midlayer doesn't retry the command. But quite often a retry
would succeed, whereas an unnecessary retry doesn't really hurt anything.
This patch uses a recently-implemented flag to tell the SCSI midlayer that
such hardware errors should be retried.

This patch causes a port reset whenever there's a transport error or abort.
If that fails it reverts back to doing a mass-storage device reset. It

This patch does two things to help reset recovery. It started life as
as496 and was rediffed by me.
First, the patch checks the result of a CLEAR_HALT request and doesn't reset the
endpoint's data toggle unless the request succeeded.
Second, it reduces the timeout for a device reset from 20 seconds to 5
seconds.
If all goes well, then I've finally figured quilt out and this patch should
apply cleanly.

This provides declarations for new requests, descriptors, and bitfields as
defined in the Wireless USB 1.0 spec. Device support will involve a new
"Wire Adapter" device class, connecting a USB Host to a cluster of wireless
USB devices. There will be two adapter types:
* Host Wireless Adapter (HWA): the downstream link is wireless, which
connects a wireless USB host to wireless USB devices (not unlike like
a hub) including to the second type of adapter.
* Device Wireless Adapter (DWA): the upstream link is wireless, for
connecting existing USB devices through wired links into the cluser.
All wireless USB devices will need persistent (and secure!) key storage, and
it's probable that Linux -- or device firmware -- will need to be involved
with that to bootstrap the initial secure key exchange.
Some user interface is required in that initial key exchange, and since the
most "hands-off" one is a wired USB link, I suspect wireless operation will
usually not be the only mode for wireless USB devices. (Plus, devices can
recharge batteries using wired USB...) All other key exchange protocols need
error prone user interactions, like copying and/or verifying keys.
It'll likely be a while before we have commercial Wireless USB hardware,
much less Linux implementations that know how to use it.

The itd_patch() function is responsible for allocating entries in the
buffer page pointer list of the iTD. Particularly, a new page pointer
is needed every time when buffer data crosses a page boundary.
However, there is a bug in the allocation logic: the function does not
allocate a new entry when the current transaction is the first
transaction in the iTD (as indicated by first!=0).
The consequence is that, when the data of the first transaction begins
somewhere at the end of a page so that it actually does cross the page
boundary, no new page pointer is allocated. This means that the data
at the end of the first transaction (beyond the page boundary) will be
accessed by the HC using the second page pointer, which is zero.
Furthermore, the first page pointer will be later overwritten by the
page pointers of the other transactions, which will garble it because
the value is or-ed into the iTD field.
All this particular check (for !first) does is cause incorrect
behaviour, so it should be entirely removed (and with it the variable
first that is not used for anything else).

This patch changes the way uhci-hcd detects valid ports. The
specification doesn't mention any way to find out how many ports a
controller has, so the driver has to use some heuristics, reading the port
status and control register and deciding whether the value makes sense.
With this patch the driver will recognize a typical failure mode (all bits
set to one) for nonexistent ports and won't assume there are always at
least 2 ports -- such an assumption seems silly if the heuristics have
already shown that the ports don't exist.
