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. Signed-off-by:

sys_sigreturn and sys_rt_sigreturn don't take any arguments. So luckily this resulted only in unneeded instead of incorrect code. But still this clearly shows why one should not put extern declarations in C files (will be fixed with a larger sparse patch). Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

Currently, we don't do much on no path or no device situations during normal user I/O, since we rely on reports regarding those events by the machine. If we trigger a path verification to bring our device state up-to-date, we (a) may recover from path failures earlier and (b) better handle situations where the hardware/hypervisor doesn't give us enough notifications.

The num_interrupt_in, num_bulk_in, and other checks in the usb-serial code are just wrong, there are too many different devices out there with different numbers of endpoints. 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.

http://bugzilla.kernel.org/show_bug.cgi?id=10124 this change: commit 08f1c192 Author: Muli Ben-Yehuda <muli@il.ibm.com> Date: Sun Jul 22 00:23:39 2007 +0300 x86-64: introduce struct pci_sysdata to facilitate sharing of ->sysdata This patch introduces struct pci_sysdata to x86 and x86-64, and converts the existing two users (NUMA, Calgary) to use it. This lays the groundwork for having other users of sysdata, such as the PCI domains work. The Calgary bits are tested, the NUMA bits just look ok. replaces pcibios_scan_root by pci_scan_bus_parented... but in pcibios_scan_root we have a check about scanned busses.
