ccb21774 - MIPS: UAPI: unexport unistd_nr_{n32,n64,o32}.h

MIPS: UAPI: unexport unistd_nr_{n32,n64,o32}.hunistd_nr_{n32,n64,o32}.h are needed only by include/asm/unistd.h,which is a kernel-side header file, and their contents is generallynot for userland use.Move their target destination from include/generated/uapi/asm/ toinclude/generated/asm/ to disable exporting them as UAPI headers.Signed-off-by: Alexander Lobakin Signed-off-by: Thomas Bogendoerfer List of files: /linux-6.15/arch/mips/include/uapi/asm/Kbuild

MIPS: Retire kvm paravirtparavirt machine was introduced for Cavium's partial virtualizationtechnology, however, it's host side support and QEMU support neverlanded in upstream.As Cavium was acquired by Marvel and they have no intention to maintaintheir MIPS product line, also paravirt is unlikely to be utilized bycommunity users, it's time to retire it if nobody steps in to maintainit.Signed-off-by: Jiaxun Yang Signed-off-by: Thomas Bogendoerfer List of files: /linux-6.15/arch/mips/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/mips/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/mips/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/mips/include/uapi/asm/Kbuild

ebb5e78c - MIPS: Initial implementation of a VDSO

Wed, 21 Oct 2015 08:54:38 +0000

MIPS: Initial implementation of a VDSOAdd an initial implementation of a proper (i.e. an ELF shared library)VDSO. With this commit it does not export any symbols, it only replacesthe current signal return trampoline page. A later commit will add userimplementations of gettimeofday()/clock_gettime().To support both new toolchains and old ones which don't generate ABIflags section, we define its content manually and then use a tool(genvdso) to patch up the section to have the correct name and type.genvdso also extracts symbol offsets ({,rt_}sigreturn) needed by thekernel, and generates a C file containing a "struct mips_vdso_image"containing both the VDSO data and these offsets. This C file iscompiled into the kernel.On 64-bit kernels we require a different VDSO for each supported ABI,so we may build up to 3 different VDSOs. The VDSO to use is selected bythe mips_abi structure.A kernel/user shared data page is created and mapped below the VDSOimage. This is currently empty, but will be used by the user timefunction implementations which are added later.[markos.chandras@imgtec.com:- Add more comments- Move abi detection in genvdso.h since it's the get_symbol functionthat needs it.- Add an R6 specific way to calculate the base address of VDSO in orderto avoid the branch instruction which affects performance.- Do not patch .gnu.attributes since it's not needed for dynamic linking.- Simplify Makefile a little bit.- checkpatch fixes- Restrict VDSO support for binutils < 2.25 for pre-R6- Include atomic64.h for O32 variant on MIPS64]Signed-off-by: Alex Smith Signed-off-by: Markos Chandras Cc: Matthew Fortune Cc: linux-mips@linux-mips.orgPatchwork: https://patchwork.linux-mips.org/patch/11337/Signed-off-by: Ralf Baechle List of files: /linux-6.15/arch/mips/include/uapi/asm/Kbuild
