2015-11-11mpt2sas: Move Gen2 HBA's device registration to a separate fileSreekanth Reddy
1. Create a mpt2sas_module.c file for mpt2sas where GEN2 HBA devices register with PCI, SML, IOCTL subsystems. 2. Updated the Makefile to use the object files from mpt3sas folder. 3. Defined a compilation flag SCSI_MPT2SAS which can be used to not include those sections of code from mpt3sas driver which are not required for mpt2sas driver. 4. Inherited automatic diag buffer feature from mpt3sas driver.

We should assign the MTD dev.of_node instead of the parser data field. This gets us the equivalent partition parser behavior with fewer special fields and parameter passing.

2015-11-11mtd: nand: drop unnecessary partition parser dataBrian Norris
All of these drivers set up a parser data struct just to communicate DT partition data. This field has been deprecated and is instead supported by telling nand_scan_ident() about the 'flash_node'. This patch: * sets chip->flash_node for those drivers that didn't already (but used OF partitioning) * drops the parser data * switches to the simpler mtd_device_register() where possible, now that we've eliminated one of the auxiliary parameters Now that we've assigned chip->flash_node for these drivers, we can probably rely on nand_dt_init() to do more of the DT parsing for us, but for now, I don't want to fiddle with each of these drivers. The parsing is done in duplicate for now on some drivers. I don't think this should break things. (Famous last words.)

2015-11-11mtd: ofpart: grab device tree node directly from master device nodeBrian Norris
It seems more logical to use a device node directly associated with the MTD master device (i.e., mtd->dev.of_node field) rather than requiring auxiliary partition parser information to be passed in by the driver in a separate struct. This patch supports the mtd->dev.of_node field and deprecates the parser data 'of_node' field Driver conversions may now follow. Additional side benefit to assigning mtd->dev.of_node rather than using parser data: the driver core will automatically create a device -> node symlink for us.

2015-11-11perf probe: Verify parameters in two functionsWang Nan
On kernel with only one out of CONFIG_KPROBE_EVENTS and CONFIG_UPROBE_EVENTS enabled, 'perf probe -d' causes a segfault because perf_del_probe_events() calls probe_file__get_events() with a negative fd. This patch fixes it by adding parameter validation at the entry of probe_file__get_events() and probe_file__get_rawlist(). Since they are both non-static public functions (in .h file), parameter verifying is required. v1 -> v2: Verify fd at the head of probe_file__get_rawlist() instead of checking at call site (suggested by Masami and Arnaldo at [1,2]).

2015-11-11perf annotate: Support full source file paths for srcline fixMichael Petlan
The --full-paths option did not show the full source file paths in the 'perf annotate' tool, because the value of the option was not propagated into the related functions. With this patch the value of the --full-paths option is known to the function that composes the srcline string, so it prints the full path when necessary.

2015-11-11MIPS: Make MIPS_CMDLINE_DTB defaultJonas Gorski
Seval of-enabled machines (bmips, lantiq, xlp, pistachio, ralink) copied the arguments from dtb to arcs_command_line to prevent the kernel from overwriting them. Since there is now an option to keep the dtb arguments, default to the new option remove the "backup" to arcs_command_line in case of USE_OF is enabled, except for those platforms that still take the bootloader arguments or do not use any at all.
