* s390/vmcore: use vmcore for zfcpdumpMichael Holzheu2013-09-111-3/+3
| | | | | | | | | | | | | Modify the s390 copy_oldmem_page() and remap_oldmem_pfn_range() function for zfcpdump to read from the HSA memory if memory below HSA_SIZE bytes is requested. Otherwise real memory is used.

* rtc: simplify devm_request_mem_region/devm_ioremapJulia Lawall2013-09-119-107/+37
| | | | | | | | | | | | | | | | | | | | Convert the composition of devm_request_mem_region and devm_ioremap to a single call to devm_ioremap_resource. The associated call to platform_get_resource is also simplified and moved next to the new call to devm_ioremap_resource. This was done using a combination of the semantic patches devm_ioremap_resource.cocci and devm_request_and_ioremap.cocci, found in the scripts/coccinelle/api directory. In rtc-lpc32xx.c and rtc-mv.c, the local variable size is no longer needed. In rtc-ds1511.c the size field of the local structure is not useful any more, and is deleted.

| | | | | | | | | | | | | | | | As reported by Joe Perches: OOM messages generally aren't useful. dmi_alloc is either a trivial front-end to kzalloc, and kzalloc already does a dump_stack() when OOM, or for x86, dmi_alloc uses extend_brk which BUGs when unsuccessful. So we can remove all 6 such log messages in the dmi_scan driver, to shrink the binary size (by 528 bytes on x86_64.)

* cciss: set max scatter gather entries to 32 on P600Mike Miller2013-09-111-0/+7
| | | | | | | | | | | | | | | | | | | | | | At one time we used to set the maximum number of scatter gather elements on all Smart Array controllers to 32. At some point in time the firmware began to write the "appropriate" value for each controller into the config table. The cciss driver would then read that and set h->maxsgentries. h->maxsgentries = readl(&(h->cfgtable->MaxSGElements); On the P600 that value is 544. Under some workloads a significant performance reduction may result. This patch forces the P600 to use only 32 scatter gather elements. Other controllers are not affected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch, originally authored by Arve Hjonnevag and Todd Poynor, prevents the system from entering suspend mode until the power supply plug, unplug, or any other change of state event is fully processed. This guarantees that the screen lights up and displays the battery charging state. The implementation uses the power supply wakeup_source object.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add driver support for the Texas Instruments BQ24190 battery charger. Some of the information provided by the device is about the charger and other information is about the battery so create two power_supply objects (one for each) and provide the appropriate information for each one. The device has many fields that go beyond what is reasonable to report or modify using the existing 'POWER_SUPPLY_PROP_*' properties so the driver exports the register fields via sysfs. They are prefixed by 'f_' (for 'field') to make it easier to distinguish between a register field and a "normal" sysfs file exported by the power_supply infrastructure. Signed-off-by: Mark A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nearly all the other goldfish peripherals (mtd, keyboard, etc) have a dependency on the main platform's GOLDFISH Kconfig item, but this one got skipped. Even with consistency as a justification, there was initial resistance[1] from some people to adding it however, as they wanted the extra compile coverage. Now, with CONFIG_COMPILE_TEST, we have the middle ground that will give people the coverage who want it, and let those who don't want it to skip ever seeing the option presented.
