This fixes a bug caused by changes of pointer type in commit f1fda895. hose->cfg_addr type is "volatile unsigned int __iomem *", so "hose->cfg_addr + X" will not make an intended address. This patch also adds comments for usage of cfg_addr and cfg_data in pci_controller structure. We use them in irregular way, and the original code is short of explanations about them.

We were using the platform_device.id field to identify which ethernet port is used for mv643xx_eth device. This is not generally correct. It will be incorrect, for example, if a hardware platform uses a single port but not the first port. Here, we add an explicit port_number field to struct mv643xx_eth_platform_data. This makes the mv643xx_eth_platform_data structure required, but that isn't an issue since all users currently provide it already.

Per device data such as brightness belongs to the indivdual device and should therefore be separate from the the backlight operation function pointers. This patch splits the two types of data and allows simplifcation of some code. Signed-off-by: NRichard Purdie <rpurdie@rpsys.net>
-
由 Richard Purdie 提交于
backlight_device->sem has a very specific use as documented in the header file. The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it. Also update the lcd class in a similar way. Signed-off-by: NRichard Purdie <rpurdie@rpsys.net>

During power outages, the UPS notifies the system for a shutdown. In the current setup, it isn't possible to poweron when power is restored. This patch fixes the issue by calling the right ibm,power-off-ups token during such events. It also adds a sysfs interface so userspace can specify whether or not to power on when power is restored.

Move all the pseries kexec code into one file, platforms/pseries/kexec.c Provide helpers for setting up ppc_md.kexec_cpu_down, so that we don't have to have #ifdef CONFIG_KEXEC in setup.c Move the initialisation of the ppc_md kexec callbacks into an init routine.

Following the example of platforms/pasemi, consolidate a couple of tiny header files in platforms/pseries into pseries.h.

For SCHED_RR tasks we can do some really trivial timeslicing. Basically we fire up a time for every scheduler tick that searches for a higher or same priority thread that is on the runqueue and if there is one context switches to it. Because we can't lock spus from timer context we actually run this from a delayed runqueue instead of a timer. A nice optimization would be to skip the actual priority bitmap search when there are less contexts than physical spus available. To implement this I need a so far unpublished patch from Andre, and it will be added after we have that patch in. Note that right now we only do the time slicing for SCHED_RR tasks. The code would work for SCHED_OTHER tasks aswell, but their prio value is defered from the one the PPU thread has at time of spu_run, and using this for spu scheduling decisions would make the code very unfair. SCHED_OTHER support will be enabled once we the spu scheduler knows how to calculcate cpu_context.prio (very soon) Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NArnd Bergmann <arnd.bergmann@de.ibm.com>
