[PATCH] ACPI-based PCI resources: PCMCIA bugfix, but resources missing in trees
Don't auto-configure yenta sockets for PCMCIA devices if it is connected to
the root PCI bus on the x86 or x86_64 architectures. Previously, this was
handled by the "ioport_resource"/"iomem_resource" check a few lines below,
but with the new ACPI-based resource handling this doesn't catch all cases
any longer.
pci-yenta-cardbus-fix.patch and this patch should solve the initialization
time trouble. However, the ACPI-based PCI resource handling is badly
broken, IMHO:
- many resources of devices don't show up in the resource trees (
/proc/iomem and /proc/ioports) any longer. This means that PCMCIA, but
also possibly other subsystems (ISA, PnP, ...) do not know which resources
it cannot use.
- verify_root_windows() should fail if there are no iomem _or_ ioport
resources, not only if there are no iomem _and_ ioport resources.

[PATCH] pcmcia: 8 and 16 bit access for static_map
The PCMCIA card services layer is never setting the i/o map attributes when
SS_CAP_STATIC_MAP is specified. Net result, sockets' set_io_map() calls
always see requests with most flags clear, meaning 8 bit access.
For hardware that always autosizes, that won't matter; and all current
STATIC_MAP drivers ignore those attributes. A new driver (for at91rm9200)
suffers badly from this, since this forces everything into 8 bit mode and
that breaks both (a) cards requiring 16 bit access, and (b) ide-cs; but of
course 8-bit cards work OK (as does accessing card attributes).
So this patch arranges to pass the attributes down, matching the behavior
for non-static mappings (using the first/only I/O window).

In -mm1 the cardbus resources might be assigned in

[PATCH] ide: sensible probing for PCI systems
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.

[PATCH] kprobes/ia64: refuse inserting kprobe on slot 1
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.

[PATCH] Return probe redesign: ppc64 specific implementation
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.)

[PATCH] Return probe redesign: ia64 specific implementation
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.
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.

kretprobe_trampoline

[PATCH] Return probe redesign: x86_64 specific changes
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.)
