2017-11-02License cleanup: add SPDX license identifier to uapi header files with no ↵Greg Kroah-Hartman1-0/+1
license Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". otherwise syscall usage would not be possible. Update the files which contain no license information with an SPDX license identifier. The chosen identifier is 'GPL-2.0 WITH Linux-syscall-note' which is the officially assigned identifier for the Linux syscall exception. SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

2016-06-10KVM: s390: Add sthyi emulationJanosch Frank1-0/+1
Store Hypervisor Information is an emulated z/VM instruction that provides a guest with basic information about the layers it is running on. This includes information about the cpu configuration of both the machine and the lpar, as well as their names, machine model and machine type. This information enables an application to determine the maximum capacity of CPs and IFLs available to software. The instruction is available whenever the facility bit 74 is set, otherwise executing it results in an operation exception. It is important to check the validity flags in the sections before using data from any structure member. It is not guaranteed that all members will be valid on all machines / machine configurations.

2015-03-06KVM: s390: fix instruction interception trace pointDavid Hildenbrand1-2/+2
trace-cmd fails to parse the instruction interception trace point: "Error: expected type 5 but read 4 failed to read event print fmt for kvm_s390_intercept_instruction" The result is an unformatted string in the output, with a warning: "kvm_s390_intercept_instruction: [FAILED TO PARSE]..." So let's add parentheses around the instruction parser macro to fix the format parsing.

2014-06-26KVM: s390: add sie.h uapi header file to Kbuild and remove header dependencyHeiko Carstens1-14/+12
sie.h was missing in arch/s390/include/uapi/asm/Kbuild and therefore missed the "make headers_check" target. If added it reveals that also arch/s390/include/asm/sigp.h would become uapi. This is something we certainly do not want. So remove that dependency as well. The header file was merged with ceae283bb2e0176c "KVM: s390: add sie exit reasons tables", therefore we never had a kernel release with this commit and can still change anything.

2014-05-16KVM: s390: decoder of SIE intercepted instructionsAlexander Yarygin1-0/+33
This patch adds a new decoder of SIE intercepted instructions. The decoder implemented as a macro and potentially can be used in both kernelspace and userspace. Note that this simplified instruction decoder is only intended to be used with the subset of instructions that may cause a SIE intercept.
