The 32-bit and 64-bit versions of copy_thread have functionally identical handling for copying the I/O bitmap, modulo differences in error handling. Clean up the error paths in both by moving the copy of the I/O bitmap to the end, to eliminate the need to free it if subsequent copy steps fail; move the resulting identical code to a static inline in a common header.

From: Martin Schwidefsky <schwidefsky at de.ibm.com> The SIE instruction on s390 uses the 2nd half of the page table page to virtualize the storage keys of a guest. This patch offers the s390_enable_sie function, which reorganizes the page tables of a single-threaded process to reserve space in the page table: s390_enable_sie makes sure that the process is single threaded and then uses

This patch series makes it possible to compile out the userspace IO system calls, iopl and ioperm. The first patch does some 32/64 unification in copy_thread to make subsequent changes easier. The second patch simplifies the complex calculation of the TSS segment limit, which also makes it easier to change in the last patch. Patches 3-9 introduce helpers to make it easier to compile out IO.

This patch series introduces a backend for kvm to run on IBM System z machines that uses the mainframe's sie virtualization capability. This work runs 64bit guests on z800/z890/z900/z990/z9/z10 class machines with a 64bit linux host. Userspace will follow once we're done brushing it over. The patch queue consists of the following patches, which can be applied in sequence on top of kvm.git
