2014-12-07cifs: convert printk(LEVEL...) to pr_<level>Andy Shevchenko

2014-12-07cifs: convert to print_hex_dump() instead of custom implementationAndy Shevchenko
This patch converts custom dumper to use native print_hex_dump() instead. The cifs_dump_mem() will have an offsets per each line which differs it from the original code. In the dump_smb() we may use native print_hex_dump() as well. It will show slightly different output in ASCII part when character is unprintable, otherwise it keeps same structure.

2014-12-07can: dev: Consolidate and unify state change handlingAndri Yngvason
The handling of can error states is different between platforms. This is an attempt to correct that problem. I've moved this handling into a generic function for changing the error state. This ensures that error state changes are handled the same way everywhere (where this function is used). This new mechanism also adds reverse state transitioning in error frames, i.e. the user will be notified through the socket interface when the state goes down.

Several can modules in drivers/net/can use a banner[] variable at the top which defines a string that is used once during init. This string is also embedded with KERN_INFO which makes it printk() specific. Improve the code by eliminating the banner[] variable and moving the string to where it is printed. Then switch from printk(KERN_INFO to pr_info() for the lines that were changed. This patch is similar to [1] which was applied to net/can.

2014-12-06i40e: get pf_id from HW rather than PCI functionShannon Nelson
Getting the pf_id from the function number was a good place to start, but when the PF was setup in passthru mode, the PCI bus/device/function was virtualized and the number in the VM is different from the number in the bare metal. This caused HW configuration issues when the wrong pf_id was used to set up the HMC and other structures. The PF_FUNC_RID register has the real bus/device/function information as configured by the BIOS, so use that for a better number. This works in NPAR mode as well.

Since our driver supports multiple VSIs per PF that need to talk to each other make sure to enable Loopback for the PF and FDIR VSI as well. Also, we now have to explicitly enable Loopback mode otherwise we fail VSI creation for VMDq and VF VSIs.

2014-12-06i40evf: make early init sequence even more robustMitch Williams
When multiple VFs attempt to initialize simultaneously, the firmware may delay or drop messages. Make the init code more adept at handling these situations by a) reinitializing the admin queue if the firmware fails to process a request, and b) resending a request if the PF doesn't answer. Once the request has been sent again, the PF might end up getting both requests and send the configuration information to the driver twice. This will cause the VF to complain about receiving an unexpected message from the PF. Since this is not fatal, reduce the warning level of the log messages that are generated in response to this event.
