Since commit e58aa3d2 ("genirq: run irq handlers with interrupts disabled") we run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled - see commit b738a50a ("genirq: warn when handler enables interrupts"). So now this flag is a NOOP and can be removed.

Some rtc drivers use the ioctl method instead of the alarm_irq_enable method for enabling alarm interupts. With the new virtualized RTC rework, its important for drivers to use the alarm_irq_enable instead. This patch converts the drivers that use the AIE ioctl method to use the alarm_irq_enable method. Other ioctl cmds are left untouched. I have not been able to test or even compile most of these drivers. Any help to make sure this change is correct would be appreciated!

This patch fixes a nasty initialization condition on the RTSR register. Sometimes, bit 1 will wake up set, sometimes not. This can be seen by checking the value of the RTSR by typing '$ cat /proc/driver/rtc', which has been provided by the previous patch. If this bit is set, the command '$ cat /dev/rtc0' will lock the system in an endless interrupt routine calling loop. This patch fixes the issue both at sa1100_rtc_probe(), where it avoids a spurious interrupt from happening, and at sa1100_rtc_interrupt(), which is the robust solution, though it does not avoid the first spurious interrupt.

Some rtc-sa1100 bugfixes: - The read_alarm() method reports the rtc_wkalrm.enabled field properly. This patch is already in the handhelds.org tree. - And the set_alarm() method now handles that flag correctly, rather than making mismatched {en,dis}able_irq_wake() calls, which trigger runtime warning messages. (Those calls are best made in suspend/resume methods.) Note that while this SA1100/PXA RTC is fully capable of waking those ARM processors from sleep states, that mechanism isn't properly supported on either processor family, or in this driver. Some boards have board-specific PM glue providing partial workarounds for the weak generic PM support.
