2008-06-13rtc: Ramtron FM3130 RTC supportSergey Lapin
Ramtron FM3130 is a chip with two separate devices inside, RTC clock and FRAM. This driver provides only RTC functionality. This chip is met in lots of custom boards with AT91SAMXXXX CPU I work with, is cheap and in no way better or worse than any other RTC on market. While it is mostly met on much smaller devices, I think it is great to have it supported in Linux.

2008-06-13rtc: make HPET_RTC_IRQ track HPET_EMULATE_RTCDavid Brownell
More Kconfig tweaks related to the legacy PC RTC code: - Describe the legacy PC RTC driver as such ... it's never quite been clear that this driver is for PC RTCs, and now it's fair to call this the "legacy" driver. - Force it to understand about HPET stealing its IRQs ... kernel code does this always when HPET is in use, there should be no option for users to goof up the config.

2008-06-13provide rtc_cmos platform deviceStas Sergeev
Recently (around 2.6.25) I've noticed that RTC no longer works for me. It turned out this is because I use pnpacpi=off kernel option to work around the parport_pc bugs. I always did so, but RTC used to work fine in the past, and now it have regressed. The patch fixes the problem by creating the platform device for the RTC when PNP is disabled. This may also help running the PNP-enabled kernel on an older PCs.

2008-06-12net: Eliminate flush_scheduled_work() calls while RTNL is held.David S. Miller
If the RTNL is held when we invoke flush_scheduled_work() we could deadlock. One such case is linkwatch, it is a work struct which tries to grab the RTNL semaphore. The most common case are net driver ->stop() methods. The simplest conversion is to instead use cancel_{delayed_}work_sync() explicitly on the various work struct the driver uses. This is an OK transformation because these work structs are doing things like resetting the chip, restarting link negotiation, and so forth. And if we're bringing down the device, we're about to turn the chip off and reset it anways. So if we cancel a pending work event, that's fine here. Some drivers were working around this deadlock by using a msleep() polling loop of some sort, and those cases are converted to instead use cancel_{delayed_}work_sync() as well.

2008-06-12USB: don't use reset-resume if drivers don't support itLinus Torvalds
This patch tries to identify which devices are able to accept reset-resume handling, by checking that there is at least one interface driver bound and that all of the drivers have a reset_resume method defined. If these conditions don't hold then during resume processing, the device is logicall disconnected. This is only a temporary fix. Later on we will explicitly unbind drivers that can't handle reset-resumes.
