2008-04-28return pfn from direct_access, for XIPJared Hulbert
Alter the block device ->direct_access() API to work with the new get_xip_mem() API (that requires both kaddr and pfn are returned). Some architectures will not do the right thing in their virt_to_page() for use by XIP (to translate from the kernel virtual address returned by direct_access(), to a user mappable pfn in XIP's page fault handler. However, we can't switch it to just return the pfn and not the kaddr, because we have no good way to get a kva from a pfn, and XIP requires the kva for its read(2) and write(2) handlers. So we have to return both.

2008-04-27[SCSI] zfcp: Add some statistics provided by the FCP adapter to the sysfsSwen Schillig
The new FCP adapter statistics provide a variety of information about the virtual adapter (subchannel). In order to collect this information the zfcp driver is extended to query this information. The information provided by the new FCP adapter statistics can be fetched by reading from the following files in the sysfs filesystem /sys/class/scsi_host/host<n>/seconds_active /sys/class/scsi_host/host<n>/requests /sys/class/scsi_host/host<n>/megabytes /sys/class/scsi_host/host<n>/utilization These are the statistics on a virtual adapter (subchannel) level. The information provided is raw and not modified or interpreted by any means. No interpretation or modification of the values is done by the zfcp driver.

2008-04-27s390: KVM guest: virtio device support, and kvm hypercallsChristian Borntraeger
This patch implements kvm guest kernel support for paravirtualized devices and contains two parts: o a basic virtio stub using virtio_ring and external interrupts and hypercalls o full hypercall implementation in kvm_para.h Currently we dont have PCI on s390. Making virtio_pci usable for s390 seems more complicated that providing an own stub. This virtio stub is similar to the lguest one, the memory for the descriptors and the device detection is made via additional mapped memory on top of the guest storage. We use an external interrupt with extint code 0x2603 for host->guest notification. The hypercall definition uses the diag instruction for issuing a hypercall. The parameters are written in R2-R7, the hypercall number is written in R1. This is similar to the system call ABI (svc) which can use R1 for the number and R2-R6 for the parameters.

drivers/s390/sysinfo.c uses the store system information intruction to query the system about information of the machine, the LPAR and additional hypervisors. KVM has to implement the host part for this instruction. To avoid code duplication, this patch splits the common definitions from sysinfo.c into a separate header file include/asm-s390/sysinfo.h for KVM use.

The System Reference Code (SRC) which is reported to the user gives the abbility to lookup the reason of the SIM online in the documentation of the storage server.

2008-04-17[S390] vmur: Use wait queue instead of mutex to serialize openFrank Munzert
If user space opens a unit record device node then vmur is leaving the kernel with lock open_mutex still held to prevent other processes from opening the device simultaneously. This causes lockdep to complain about a lock held when returning to user space. Now the mutex is replaced by a wait queue to serialize device open.

2008-04-17[S390] tape: duplicate sysfs filename when setting tape device onlineMichael Holzheu
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.

2008-04-17[S390] qdio: Unrecognized inbound traffic if many FCP devices are onlineUrsula Braun
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.

2008-04-17[S390] sclp: Get rid of in_atomic() use.Heiko Carstens
Reintroduces in_interrupt() check in sclp_tty code. Add may_schedule parameter to vt220 write function, so we can let the write function know if it may schedule or not. So we disallow scheduling for all console calls and may allow them for tty calls. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
