3d9683cf - KVM: export and iif KVM is supported

Mon, 18 Mar 2019 09:08:12 +0000

KVM: export and iif KVM is supportedI do not see any consistency about headers_install of and .According to my analysis of Linux 5.1-rc1, there are 3 groups: [1] Both and are exported alpha, arm, hexagon, mips, powerpc, s390, sparc, x86 [2] is exported, but is not arc, arm64, c6x, h8300, ia64, m68k, microblaze, nios2, openrisc, parisc, sh, unicore32, xtensa [3] Neither nor is exported csky, nds32, riscvThis does not match to the actual KVM support. At least, [2] ishalf-baked.Nor do arch maintainers look like they care about this. For example,commit 0add53713b1c ("microblaze: Add missing kvm_para.h to Kbuild")exported to user-space in order to fix an in-kernelbuild error.We have two ways to make this consistent: [A] export both and for all architectures, irrespective of the KVM support [B] Match the header export of and to the KVM supportMy first attempt was [A] because the code looks cleaner, but Paolosuggested [B].So, this commit goes with [B].For most architectures, was moved to the kernel-space.I changed include/uapi/linux/Kbuild so that it checks generatedasm/kvm_para.h as well as check-in ones.After this commit, there will be two groups: [1] Both and are exported arm, arm64, mips, powerpc, s390, x86 [2] Neither nor is exported alpha, arc, c6x, csky, h8300, hexagon, ia64, m68k, microblaze, nds32, nios2, openrisc, parisc, riscv, sh, sparc, unicore32, xtensaSigned-off-by: Masahiro Yamada Acked-by: Cornelia Huck Signed-off-by: Paolo Bonzini List of files: /linux-6.15/arch/sh/include/uapi/asm/Kbuild

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/sh/include/uapi/asm/Kbuild

d4ce5458 - arch: remove stale comments "UAPI Header export list"

Thu, 03 Jan 2019 01:10:37 +0000

arch: remove stale comments "UAPI Header export list"These comments are leftovers of commit fcc8487d477a ("uapi: export allheaders under uapi directories").Prior to that commit, exported headers must be explicitly added toheader-y. Now, all headers under the uapi/ directories are exported.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/sh/include/uapi/asm/Kbuild

c895f6f7 - bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type

Mon, 04 Dec 2017 09:56:44 +0000

bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program typeCommit 0515e5999a466dfe ("bpf: introduce BPF_PROG_TYPE_PERF_EVENTprogram type") introduced the bpf_perf_event_data structure whichexports the pt_regs structure. This is OK for multiple architecturesbut fail for s390 and arm64 which do not export pt_regs. Programsusing them, for example, the bpf selftest fail to compile on thesearchitectures.For s390, exporting the pt_regs is not an option because s390 wantsto allow changes to it. For arm64, there is a user_pt_regs structurethat covers parts of the pt_regs structure for use by user space.To solve the broken uapi for s390 and arm64, introduce an abstracttype for pt_regs and add an asm/bpf_perf_event.h file that concretesthe type. An asm-generic header file covers the architectures thatexport pt_regs today.The arch-specific enablement for s390 and arm64 follows in separatecommits.Reported-by: Thomas Richter Fixes: 0515e5999a466dfe ("bpf: introduce BPF_PROG_TYPE_PERF_EVENT program type")Signed-off-by: Hendrik Brueckner Reviewed-and-tested-by: Thomas Richter Acked-by: Alexei Starovoitov Cc: Arnaldo Carvalho de Melo Cc: Peter Zijlstra Cc: Ingo Molnar Cc: Alexander Shishkin Cc: Jiri Olsa Cc: Namhyung Kim Cc: Arnd Bergmann Cc: Daniel Borkmann Signed-off-by: Daniel Borkmann List of files: /linux-6.15/arch/sh/include/uapi/asm/Kbuild

89593123 - sh: move generic-y of exported headers to uapi/asm/Kbuild

Sun, 09 Jul 2017 18:32:53 +0000

sh: move generic-y of exported headers to uapi/asm/KbuildSince commit fcc8487d477a ("uapi: export all headers under uapidirectories"), all (and only) headers under uapi directories areexported, but asm-generic wrappers are still exceptions.To complete de-coupling the uapi from kernel headers, move generic-yof exported headers to uapi/asm/Kbuild.With this change, "make headers_install" will just need to parseuapi/asm/Kbuild to build up exported headers.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/sh/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/sh/include/uapi/asm/Kbuild
