037fc336 - kbuild: force all architectures except um to include mandatory-y

Sun, 17 Mar 2019 02:01:09 +0000

kbuild: force all architectures except um to include mandatory-yCurrently, every arch/*/include/uapi/asm/Kbuild explicitly includesthe common Kbuild.asm file. Factor out the duplicated include directivesto scripts/Makefile.asm-generic so that no architecture would opt outof the mandatory-y mechanism.um is not forced to include mandatory-y since it is a very exceptionalcase which does not support UAPI.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/s390/include/uapi/asm/Kbuild

26293b31 - y2038: s390: Remove unneeded ipc uapi header files

Tue, 05 May 2015 20:47:56 +0000

y2038: s390: Remove unneeded ipc uapi header filesThe s390 msgbuf/sembuf/shmbuf header files are all identical to theversion from asm-generic.This patch removes the files and replaces them with 'generic-y'statements, to avoid having to modify each copy when we extend sysvipcto deal with 64-bit time_t in 32-bit user space.Note that unlike alpha and ia64, the ipcbuf.h header file is slightlydifferent here, so I'm leaving the private copy.To deal with 32-bit compat tasks, we also have to adapt the definitionsof compat_{shm,sem,msg}id_ds to match the changes to the respectiveasm-generic files.Acked-by: Heiko Carstens Signed-off-by: Arnd Bergmann List of files: /linux-6.15/arch/s390/include/uapi/asm/Kbuild

3cb8f11c - s390: use generic uapi/asm/swab.h

Wed, 02 Aug 2017 07:45:02 +0000

s390: use generic uapi/asm/swab.hclang doesn't like s390 specific inline assembler constraints. Theseare present in our arch specific uapi/asm/swab.h which again isrequired by some ebpf test cases.For current compiler versions the generic swab.h already makes use ofgcc's builtin functions. Therefore we can simply remove our own headerfile and use the generic one.This will generate worse code if used with compilers before gcc 4.8,which has no __builtin_bswap16(); or before gcc v4.4, which has no__builtin_bswap[32|64](). For these cases a C implementation fallbackwould be used which generates more code, but is still correct (170KBextra code for gcc 4.3 with performance_defconfig).However given that we need (and want) to get rid of the inlineassemblies anyway in order to be able to use clang, the above is justa minor drawback if old gcc compilers are used.With current compilers there is close to zero difference, except forthree btrfs bit functions which generate more out-of-line code. Thegenerated code looks still correct and also uses the s390 specificbyteswap instructions.Reported-and-tested-by: Thomas Richter Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky List of files: /linux-6.15/arch/s390/include/uapi/asm/Kbuild

fcc8487d - uapi: export all headers under uapi directories

Mon, 27 Mar 2017 12:20:15 +0000

uapi: export all headers under uapi directoriesRegularly, when a new header is created in include/uapi/, the developerforgets to add it in the corresponding Kbuild file. This error is usuallydetected after the release is out.In fact, all headers under uapi directories should be exported, thus it'suseless to have an exhaustive list.After this patch, the following files, which were not exported, are nowexported (with make headers_install_all):asm-arc/kvm_para.hasm-arc/ucontext.hasm-blackfin/shmparam.hasm-blackfin/ucontext.hasm-c6x/shmparam.hasm-c6x/ucontext.hasm-cris/kvm_para.hasm-h8300/shmparam.hasm-h8300/ucontext.hasm-hexagon/shmparam.hasm-m32r/kvm_para.hasm-m68k/kvm_para.hasm-m68k/shmparam.hasm-metag/kvm_para.hasm-metag/shmparam.hasm-metag/ucontext.hasm-mips/hwcap.hasm-mips/reg.hasm-mips/ucontext.hasm-nios2/kvm_para.hasm-nios2/ucontext.hasm-openrisc/shmparam.hasm-parisc/kvm_para.hasm-powerpc/perf_regs.hasm-sh/kvm_para.hasm-sh/ucontext.hasm-tile/shmparam.hasm-unicore32/shmparam.hasm-unicore32/ucontext.hasm-x86/hwcap2.hasm-xtensa/kvm_para.hdrm/armada_drm.hdrm/etnaviv_drm.hdrm/vgem_drm.hlinux/aspeed-lpc-ctrl.hlinux/auto_dev-ioctl.hlinux/bcache.hlinux/btrfs_tree.hlinux/can/vxcan.hlinux/cifs/cifs_mount.hlinux/coresight-stm.hlinux/cryptouser.hlinux/fsmap.hlinux/genwqe/genwqe_card.hlinux/hash_info.hlinux/kcm.hlinux/kcov.hlinux/kfd_ioctl.hlinux/lightnvm.hlinux/module.hlinux/nbd-netlink.hlinux/nilfs2_api.hlinux/nilfs2_ondisk.hlinux/nsfs.hlinux/pr.hlinux/qrtr.hlinux/rpmsg.hlinux/sched/types.hlinux/sed-opal.hlinux/smc.hlinux/smc_diag.hlinux/stm.hlinux/switchtec_ioctl.hlinux/vfio_ccw.hlinux/wil6210_uapi.hrdma/bnxt_re-abi.hNote that I have removed from this list the files which are generated in everyexported directories (like .install or .install.cmd).Thanks to Julien Floret for the tip to get allsubdirs with a pure makefile command.For the record, note that exported files for asm directories are a mix offiles listed by: - include/uapi/asm-generic/Kbuild.asm; - arch//include/uapi/asm/Kbuild; - arch//include/asm/Kbuild.Signed-off-by: Nicolas Dichtel Acked-by: Daniel Vetter Acked-by: Russell King Acked-by: Mark Salter Acked-by: Michael Ellerman (powerpc)Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/s390/include/uapi/asm/Kbuild

916cda1a - s390: add a system call for guarded storage

Tue, 26 Jan 2016 13:10:34 +0000

s390: add a system call for guarded storageThis adds a new system call to enable the use of guarded storage foruser space processes. The system call takes two arguments, a commandand pointer to a guarded storage control block: s390_guarded_storage(int command, struct gs_cb *gs_cb);The second argument is relevant only for the GS_SET_BC_CB command.The commands in detail:0 - GS_ENABLE Enable the guarded storage facility for the current task. The initial content of the guarded storage control block will be all zeros. After the enablement the user space code can use load-guarded-storage-controls instruction (LGSC) to load an arbitrary control block. While a task is enabled the kernel will save and restore the current content of the guarded storage registers on context switch.1 - GS_DISABLE Disables the use of the guarded storage facility for the current task. The kernel will cease to save and restore the content of the guarded storage registers, the task specific content of these registers is lost.2 - GS_SET_BC_CB Set a broadcast guarded storage control block. This is called per thread and stores a specific guarded storage control block in the task struct of the current task. This control block will be used for the broadcast event GS_BROADCAST.3 - GS_CLEAR_BC_CB Clears the broadcast guarded storage control block. The guarded- storage control block is removed from the task struct that was established by GS_SET_BC_CB.4 - GS_BROADCAST Sends a broadcast to all thread siblings of the current task. Every sibling that has established a broadcast guarded storage control block will load this control block and will be enabled for guarded storage. The broadcast guarded storage control block is used up, a second broadcast without a refresh of the stored control block with GS_SET_BC_CB will not have any effect.Signed-off-by: Martin Schwidefsky List of files: /linux-6.15/arch/s390/include/uapi/asm/Kbuild

s390/pkey: Introduce pkey kernel moduleThis patch introcudes a new kernel module pkey which is providingprotected key handling and management functions. The pkey API isavailable within the kernel for other s390 specific code to createand manage protected keys. Additionally the functions are exportedto user space via IOCTL calls. The implementation makes extensiveuse of functions provided by the zcrypt device driver.
