2016-03-15PCI: designware: Add generic dw_pcie_wait_for_link()Joao Pinto
Several DesignWare-based drivers (dra7xx, exynos, imx6, keystone, qcom, and spear13xx) had similar loops waiting for the link to come up. Add a generic dw_pcie_wait_for_link() for use by all these drivers so the waiting is done consistently, e.g., always using usleep_range() rather than mdelay() and using similar timeouts and retry counts. Note that this changes the Keystone link training/wait for link strategy, so we initiate link training, then wait longer for the link to come up before re-initiating link training.

This kind of attribute can be used for data that requires a once per bootup initialization sequence, but is otherwise never modified after that point. This feature was based on the work by PaX Team and Brad Spengler. (by Kees Cook, the ARM vDSO bits by David Brown.) - make CONFIG_DEBUG_RODATA always enabled on x86 and remove the Kconfig option.

2016-03-14dm: fix rq_end_stats() NULL pointer in dm_requeue_original_request()Bryn M. Reeves
An "old" (.request_fn) DM 'struct request' stores a pointer to the associated 'struct dm_rq_target_io' in rq->special. dm_requeue_original_request(), previously named dm_requeue_unmapped_original_request(), called dm_unprep_request() to reset rq->special to NULL. But rq_end_stats() would go on to hit a NULL pointer deference because its call to tio_from_request() returned NULL.

2016-03-14rtc: ds1685: actually spin forever in poweroff error pathJosh Poimboeuf
objtool reports the following warnings: drivers/rtc/rtc-ds1685.o: warning: objtool: ds1685_rtc_work_queue()+0x0: duplicate frame pointer save drivers/rtc/rtc-ds1685.o: warning: objtool: ds1685_rtc_work_queue()+0x3: duplicate frame pointer setup drivers/rtc/rtc-ds1685.o: warning: objtool: ds1685_rtc_work_queue()+0x0: frame pointer state mismatch The warning message needs to be improved, but what it really means in this case is that ds1685_rtc_poweroff() has a possible code path where it can actually fall through to the next function in the object code, ds1685_rtc_work_queue(). The bug is caused by the use of the unreachable() macro in a place which is actually reachable. That causes gcc to assume that the printk() immediately before the unreachable() macro never returns, when in fact it does. So gcc places the printk() at the very end of the function's object code. When the printk() returns, the next function starts executing. The surrounding comment and printk message state that the code should spin forever, which explains the unreachable() statement. However the actual spin code is missing.

2016-03-14rtc: ds3232: fix issue when irq is shared several devicesAkinobu Mita
ds3232-core requests irq with IRQF_SHARED, so irq can be shared by several devices. But the irq handler for ds3232 unconditionally disables the irq at first and the irq is re-enabled only when the interrupt source was the ds3232's alarm. This behaviour breaks the devices sharing the same irq in the various scenarios. This converts to use threaded irq and remove outdated code in suspend/resume paths.

The rtctest (tools/testing/selftests/timers/rtctest.c) found that reading ds3232 rtc device immediately return the value 0x20 (RTC_AF) without waiting alarm interrupt. This is because alarm_irq_enable() of ds3232 driver changes RTC_AF flag in rtc->irq_data. So calling ioctl with RTC_AIE_ON generates invalid value in rtc device. The lower-level driver should not touch rtc->irq_data directly. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

There are several arch-specific RTC drivers that can be successfully compiled on other platforms. Add a COMPILE_TEST dependency for those. Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>
2016-03-14rtc: generic: allow building on all architecturesArnd Bergmann
There are four architectures using this driver, but since we can build it with COMPILE_TEST, we should try dealing with the absence of the asm/rtc.h header file, to avoid getting a build error: drivers/rtc/rtc-generic.c:12:21: fatal error: asm/rtc.h: No such file or directory This creates an alternative use of the driver, allowing architectures to pass a set of rtc_class_ops in platform data. We can convert the four architectures to use this and then remove the original code.

2016-03-14rtc: pcf8523: properly handle oscillator stop bitAlexandre Belloni
The time and date register of the pcf8223 are undefined after a power reset. Properly handle the OS bit and return -EINVAL when that bit is set. It is properly removed when setting the time. This solves an issue where the time and date may be valid for rtc_valid_tm() but is not the current time. Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

2016-03-14rtc: mt6397: Remove plaform module aliasJavier Martinez Canillas
The driver uses the MODULE_ALIAS() macro to export a platform module alias to allow the module to be autoloaded if the device is registered using the legacy platform registration mechanism but the driver is always used by OF only machines so the alias is not needed and should just be removed.
