The nfs41 rpc logic uses the rpc_call_prepare method to recover and create the session, as well as selecting a free slot id and the rpc_call_done to free the slot and update slot table related metadata. In the coming patches we'll add rpc prepare and done routines for setting up the sequence op and processing the sequence result.

In addition, some root port hardware might be unable to provide a correct source id, i.e., the source id, or the bus id part of the source id provided by root port might be equal to 0. The patchset implements the support in kernel by searching the device tree under the root port. Patch 1 changes parameter cb of function pci_walk_bus to return a value. When cb return non-zero, pci_walk_bus stops more searching on the device tree.

With this change, we can easily identify the hotplug driver.

It is implemented using struct hotplug_slot_attribute, but sysfs_ops for pci_slot_ktype is NOT for struct hotplug_slot_attribute, but for struct pci_slot_attribute. This bug had been there for a long time, maybe it was introduced when PCI slot framework was introduced. The reason why this bug didn't cause any problem is maybe the EMI support is not tested at all because of lack of test environment. As described above, the EMI support in pciehp seems not to be tested at all. So this patch removes EMI support from pciehp, instead of fixing the bug.

This patch will enable/disable ECRC checking by setting/clearing the ECRC Check Enable and/or ECRC Generation Enable bits for devices that support ECRC. The ECRC setting is controlled by the "pci=ecrc=<policy>" command-line option. If this option is not set or is set to 'bios", the enable and generation bits are left in whatever state that firmware/BIOS set them to. The "off" setting turns them off, and the "on" option turns them on (if the device supports it). Turning ECRC on or off can be a data integrity versus performance tradeoff. In theory, turning it on will catch more data errors, turning it off means possibly better performance since CRC does not need to be calculated by the PCIe hardware and packet sizes are reduced.

Suspend is a bit of a corner case so we try to get away without adding another hack to rfkill-input - it's going to be removed soon. If the state does change over suspend, users will simply have to prod rfkill-input twice in order to toggle the state. Userspace policy agents will be able to implement a more consistent user experience. For example, they can avoid the above problem if they toggle devices individually. Then there would be no "global state" to get out of sync. Currently there are only two rfkill drivers with persistent soft-blocked state. thinkpad-acpi already checks the software state on resume. eeepc-laptop will require modification.

This consolidates the declarations into a single declaration in one common place, include/linux/perf_counter.h. On powerpc, we continue to provide a static inline definition of set_perf_counter_pending() in the powerpc hw_irq.h. Also, this removes from the x86 perf_counter.h the unused null definitions of {test,clear}_perf_counter_pending.

An arch may implement passing of a variable that is unique to the function and can be saved on entering a function and can be tested when exiting the function. Usually the frame pointer can be used for this purpose. This patch also implements this for x86. Where it passes in the stack frame of the parent function, and will test that frame on exit. There was a case in x86_32 with optimize for size (-Os) where, for a few functions, gcc would align the stack frame and place a copy of the return address into it. The function graph tracer modified the copy and not the actual return address. On return from the funtion, it did not go to the tracer hook, but returned to the parent. This broke the function graph tracer, because the return of the parent (where gcc did not do this funky manipulation) returned to the location that the child function was suppose to. This caused strange kernel crashes. This test detected the problem and pointed out where the issue was. This modifies the parameters of one of the functions that the arch specific code calls, so it includes changes to arch code to accommodate the new prototype. Note, I notice that the parsic arch implements its own push_return_trace. This is now a generic function and the ftrace_push_return_trace should be used instead. This patch does not touch that code.
