The patch titled
Subject: rtc: add ioctl to get/clear battery low voltage status
has been removed from the -mm tree. Its filename was
rtc-add-ioctl-to-get-clear-battery-low-voltage-status.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: rtc: add ioctl to get/clear battery low voltage status
Currently there is no generic way to get the RTC battery status within an
application. So add an ioctl to read the status bit. The idea is that
the bit is set once a low voltage is detected. It stays there until it is
reset using the RTC_VL_CLR ioctl.
