* [S390] uaccess: Always access the correct address space.Heiko Carstens2008-04-171-18/+41
| | | | | | | | | | | | | | | The current uaccess page table walk code assumes at a few places that any access is a user space access. This is not correct if somebody has issued a set_fs(KERNEL_DS) in advance. Add code which checks which address space we are in and with this make sure we access the correct address space. This way we get also rid of the dirty if (!currrent-mm) return -EFAULT; hack in futex_atomic_cmpxchg_pt.

* [S390] Fix a lot of sparse warnings.Heiko Carstens2008-04-1726-64/+198
| | | | | | | | | | | Most noteable part of this commit is the new local header file entry.h which contains all the function declarations of functions that get only called from asm code or are arch internal. That way we can avoid extern declarations in C files. This is more or less the same that was done for sparc64.

I generally dislike adding optional linux/* includes in asm/* includes - I'm nervous about this causing include loops. However, there's a separate point to be discussed here. That is, what interfaces are expected of every architecture in the kernel. If generic code wants to be able to set the affinity of interrupts, then that needs to become part of the interfaces listed in linux/interrupt.h rather than linux/irq.h. So what I suggest is this approach instead (against Linus' tree of a couple of days ago) - we move irq_set_affinity() and irq_can_set_affinity() to linux/interrupt.h, change the linux/irq.h includes to linux/interrupt.h and include asm/irq_regs.h where needed (asm/irq_regs.h is supposed to be rarely used include since not much touches the stacked parent context registers.) Build tested on ARM PXA family kernels and ARM's Realview platform kernels which both use genirq.

* [S390] hw_random: allow rng_dev_read() to return hardware errors.Ralph Wuerthner2008-04-171-0/+4
| | | | | | | | | | | | | | | | The api for hardware random number generators is currently limited to devices that never fail. If the hardware is registered as a source for random numbers it has to work. This prevents the use of i/o based random number devices where the i/o might fail. Add a check for errors after the read from a hardware random number device. This patch is required to support large random numbers retrieved from the CEX2C cards on System z.

* [S390] Vertical cpu management.Heiko Carstens2008-04-174-17/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If vertical cpu polarization is active then the hypervisor will dispatch certain cpus for a longer time than other cpus for maximum performance. For example if a guest would have three virtual cpus, each of them with a share of 33 percent, then in case of vertical cpu polarization all of the processing time would be combined to a single cpu which would run all the time, while the other two cpus would get nearly no cpu time. There are three different types of vertical cpus: high, medium and low. Low cpus hardly get any real cpu time, while high cpus get a full real cpu. Medium cpus get something in between. In order to switch between the two possible modes (default is horizontal) a 0 for horizontal polarization or a 1 for vertical polarization must be written to the dispatching sysfs attribute: /sys/devices/system/cpu/dispatching The polarization of each single cpu can be figured out by the polarization sysfs attribute of each cpu: /sys/devices/system/cpu/cpuX/polarization horizontal, vertical:high, vertical:medium, vertical:low or unknown. When switching polarization the polarization attribute may contain the value unknown until the configuration change is done and the kernel has figured out the new polarization of each cpu. Note that running a system with different types of vertical cpus may result in significant performance regressions. If possible only one type of vertical cpus should be used. All other cpus should be offlined. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

* [S390] tape: duplicate sysfs filename when setting tape device onlineMichael Holzheu2008-04-173-6/+5
| | | | | | | | | | | | | | | When a tape device is set online, offline and online again, the following error message is printed on the console: "sysfs: duplicate filename 'non-rewinding' can not be created". The reason is that when setting a device online, the tape driver creates a sysfs symlink from the tape device to the tape class device. Unfortunately the symlink is not removed correctly, when the device is set offline. Instead of passing the tape device object to sysfs_remove_link, the class device object is used. This patch fixes this problem and uses the correct tape device object now.

* [S390] qdio: Unrecognized inbound traffic if many FCP devices are onlineUrsula Braun2008-04-171-1/+1
| | | | | | | | | | | | | | | | | | | Problem: Usually every FCP device has its own indicator field the adapter uses to signal outstanding work. Once a certain limit of devices is reached, a common indicator field is used. In certain scenarios qdio resets this common indicator field, but handles only part of the FCP-devices sharing the common indicator field. Thus inbound traffic on the non-processed shared FCP-devices is not recognized immediately. Solution: Make sure common indicator field is reset only, if all FCP-devices sharing the indicator are processed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a libata based PATA driver for avr32, but no support for drivers/ide/ on avr32.

We need to just be sticking with the device ids instead of trying to catch this kind of thing. It broke too many different devices. This fixes a large number of usb-serial devices to get them working properly again.
