2012-03-11regulator: twl: adapt twl-regulator driver to dtRajendra Nayak
Modify the twl regulator driver to extract the regulator_init_data from device tree when passed, instead of getting it through platform_data structures (on non-DT builds) Also add documentation for TWL regulator specific bindings.

2012-03-11regulator: twl6030: add support for vdd1, vdd2 and vdd3 regulatorsTero Kristo
vdd1 and vdd2 are now common regulators for twl4030 and twl6030. Also added vdd3 as a new regulator for twl6030. twl6030 vdd1...vdd3 smps regulator voltages can only be controlled through the smartreflex voltage channel, thus the support for the voltage_get and set is minimal and requires external controller.

2012-03-11regulator: twl4030: add support for external voltage get/setTero Kristo
This is needed for SMPS regulators, which use the OMAP voltage processor for voltage get/set functions instead of the normal I2C channel. For this purpose, regulator_init_data->driver_data contents are expanded, it is now a struct which contains function pointers for the set/get voltage operations, a data pointer for these, and the previously used features bitmask.

2012-03-11regulator: twl6030: Fix voltage selection logicLaxman Dewangan
The voltage selection logic for the twl6030 smps fails if min:max is such that min < 1300mV and max > 1300mV although this is in valid range for a regulator e.g. [x, 1350] where x < 1300. Fixing the voltage selection logic such that first it will check for min_uV for a range and then calculated value will be checked against max_uV.

2012-03-11device.h: cleanup users outside of linux/include (C files)Paul Gortmaker
For files that are actively using linux/device.h, make sure that they call it out. This will allow us to clean up some of the implicit uses of linux/device.h within include/* without introducing build regressions. Yes, this was created by "cheating" -- i.e. the headers were cleaned up, and then the fallout was found and fixed, and then the two commits were reordered. This ensures we don't introduce build regressions into the git history. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2012-03-11[S390] kernel: Add z/VM LGR detectionMichael Holzheu
Currently the following mechanisms are available to move active Linux on System z instances between machines: * z/VM 6.2 SSI (Single System Image) * Suspend/resume For moving Linux instances in this patch the term LGR (Linux Guest Relocation) is used. Because such an operation is critical, it should be detectable from Linux. With this patch for both, a live system and a kernel dump, the information about LGRs is accessible. To identify a guest, stsi and stfle data is used. A new function lgr_info_log() compares the current data (lgr_info_cur) with the last recorded one (lgr_info_last). In case the two data sets differ, lgr_info_cur is logged to the "lgr" s390dbf. The following trigger points call lgr_info_log(): * panic * die * kdump * LGR timer * PSW restart * QDIO recovery * resume This patch also changes the s390dbf hex_ascii view. Now only printable ASCII characters are shown.

2012-03-11[S390] irq: external interrupt code passingHeiko Carstens
The external interrupt handlers have a parameter called ext_int_code. Besides the name this paramter does not only contain the ext_int_code but in addition also the "cpu address" (POP) which caused the external interrupt. To make the code a bit more obvious pass a struct instead so the called function can easily distinguish between external interrupt code and cpu address. The cpu address field however is named "subcode" since some external interrupt sources do not pass a cpu address but a different parameter (or none at all).

2012-03-11[S390] rework idle codeMartin Schwidefsky
Whenever the cpu loads an enabled wait PSW it will appear as idle to the underlying host system. The code in default_idle calls vtime_stop_cpu which does the necessary voodoo to get the cpu time accounting right. The udelay code just loads an enabled wait PSW. To correct this rework the vtime_stop_cpu/vtime_start_cpu logic and move the difficult parts to entry[64].S, vtime_stop_cpu can now be called from anywhere and vtime_start_cpu is gone. The correction of the cpu time during wakeup from an enabled wait PSW is done with a critical section in entry[64].S. As vtime_start_cpu is gone, s390_idle_check can be removed as well. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2012-03-11[S390] rework smp codeMartin Schwidefsky
Define struct pcpu and merge some of the NR_CPUS arrays into it, including __cpu_logical_map, current_set and smp_cpu_state. Split smp related functions to those operating on physical cpus and the functions operating on a logical cpu number. Make the functions for physical cpus use a pointer to a struct pcpu. This hides the knowledge about cpu addresses in smp.c, entry[64].S and swsusp_asm64.S, thus remove the sigp.h header. The PSW restart mechanism is used to start secondary cpus, calling a function on an online cpu, calling a function on the ipl cpu, and for the nmi signal. Replace the different assembler functions with a single function restart_int_handler. The new entry point calls a function whose pointer is stored in the lowcore of the target cpu and it can wait for the source cpu to stop. This covers all existing use cases. Overall the code is now simpler and there are ~380 lines less code. Reviewed-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

This patch fixes a bug in tcm_fc where fc_exch memory from fc_exch_mgr->ep_pool is currently being leaked by ft_send_resp_status() usage. Following current code in ft_queue_status() response path, using lport->tt.seq_send() needs to be followed by a lport->tt.exch_done() in order to release fc_exch memory back into libfc_em kmem_cache. ft_send_resp_status() code is currently used in pre submit se_cmd ft_send_work() error exceptions, TM request setup exceptions, and main TM response callback path in ft_queue_tm_resp().

The "skipped bus generations" message was added together with the respective fw_device retaining/ reviving code in order to see how it all works out. It did well, so don't spam the log anymore. The "register access failure" situation still needs an actual handler. But at this point it makes less sense to ask folks to send mails about it. We now have a pretty good picture of what controllers emit this and when: Texas Instruments PCIxx21 FireWire + CardBus + flash memory card controller: https://bugzilla.redhat.com/show_bug.cgi?id=608544 O2 Micro FireWire + flash memory card controller: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/801719 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/881688 http://marc.info/?l=linux1394-devel&m=132309283531423 http://marc.info/?l=linux1394-devel&m=132368567907469 http://marc.info/?l=linux1394-devel&m=132516165727468 http://marc.info/?l=linux1394-devel&m=133006486927699 Pinnacle Movieboard: commit 7f7e37115a8b6724f26d0637a04e1d35e3c59717 http://marc.info/?l=linux1394-devel&m=130714243325962 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2012-03-10firewire: sbp2: replace a GFP_ATOMIC allocationStefan Richter
sbp2_send_management_orb() is called by sbp2_login, sbp2_reconnect, and sbp2_remove, all which are able to sleep during memory allocations. Actually, sbp2_send_management_orb() itself is a sleeping function. Login and remove could allocate with GFP_KERNEL but reconnect needs GFP_NOIO to ensure progress in low memory situations.
