* kbuild: update compile-test header list for v5.3-rc1Masahiro Yamada2019-07-201-8/+6
| | | | | | | | | | | | | | | | | - Some headers graduated from the blacklist - hyperv_timer.h joined the header-test when CONFIG_X86=y - nf_tables*.h joined the header-test when CONFIG_NF_TABLES is enabled. - The entry for nf_tables_offload.h was added to fix build error for the combination of CONFIG_NF_TABLES=n and CONFIG_KERNEL_HEADER_TEST=y. - The entry for iomap.h was added because this header is supposed to be included only when CONFIG_BLOCK=y Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* kbuild: compile-test kernel headers to ensure they are self-containedMasahiro Yamada2019-07-091-0/+1270
| | | | | | | | | | | | | | | | | | | | | The headers in include/ are globally used in the kernel source tree to provide common APIs. They are included from external modules, too. It will be useful to make as many headers self-contained as possible so that we do not have to rely on a specific include order. There are more than 4000 headers in include/. In my rough analysis, 70% of them are already self-contained. With efforts, most of them can be self-contained. For now, we must exclude more than 1000 headers just because they cannot be compiled as standalone units. I added them to header-test-. The blacklist was mostly generated by a script, so the reason of the breakage should be checked later.

* uapi: export all headers under uapi directoriesNicolas Dichtel2017-05-101-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regularly, when a new header is created in include/uapi/, the developer forgets to add it in the corresponding Kbuild file. This error is usually detected after the release is out. In fact, all headers under uapi directories should be exported, thus it's useless to have an exhaustive list. After this patch, the following files, which were not exported, are now exported (with make headers_install_all): asm-arc/kvm_para.h asm-arc/ucontext.h asm-blackfin/shmparam.h asm-blackfin/ucontext.h asm-c6x/shmparam.h asm-c6x/ucontext.h asm-cris/kvm_para.h asm-h8300/shmparam.h asm-h8300/ucontext.h asm-hexagon/shmparam.h asm-m32r/kvm_para.h asm-m68k/kvm_para.h asm-m68k/shmparam.h asm-metag/kvm_para.h asm-metag/shmparam.h asm-metag/ucontext.h asm-mips/hwcap.h asm-mips/reg.h asm-mips/ucontext.h asm-nios2/kvm_para.h asm-nios2/ucontext.h asm-openrisc/shmparam.h asm-parisc/kvm_para.h asm-powerpc/perf_regs.h asm-sh/kvm_para.h asm-sh/ucontext.h asm-tile/shmparam.h asm-unicore32/shmparam.h asm-unicore32/ucontext.h asm-x86/hwcap2.h asm-xtensa/kvm_para.h drm/armada_drm.h drm/etnaviv_drm.h drm/vgem_drm.h linux/aspeed-lpc-ctrl.h linux/auto_dev-ioctl.h linux/bcache.h linux/btrfs_tree.h linux/can/vxcan.h linux/cifs/cifs_mount.h linux/coresight-stm.h linux/cryptouser.h linux/fsmap.h linux/genwqe/genwqe_card.h linux/hash_info.h linux/kcm.h linux/kcov.h linux/kfd_ioctl.h linux/lightnvm.h linux/module.h linux/nbd-netlink.h linux/nilfs2_api.h linux/nilfs2_ondisk.h linux/nsfs.h linux/pr.h linux/qrtr.h linux/rpmsg.h linux/sched/types.h linux/sed-opal.h linux/smc.h linux/smc_diag.h linux/stm.h linux/switchtec_ioctl.h linux/vfio_ccw.h linux/wil6210_uapi.h rdma/bnxt_re-abi.h Note that I have removed from this list the files which are generated in every exported directories (like .install or .install.cmd). Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all subdirs with a pure makefile command. For the record, note that exported files for asm directories are a mix of files listed by: - include/uapi/asm-generic/Kbuild.asm; - arch/<arch>/include/uapi/asm/Kbuild; - arch/<arch>/include/asm/Kbuild.

* UAPI: Remove empty non-UAPI Kbuild filesDavid Howells2012-10-171-4/+0
| | | | | | | | | | | | | | | | | | Remove non-UAPI Kbuild files that have become empty as a result of UAPI disintegration. They used to have only header-y lines in them and those have now moved to the Kbuild files in the corresponding uapi/ directories. Possibly these should not be removed but rather have a comment inserted to say they are intentionally left blank. This would make it easier to add generated header lines in future without having to restore the infrastructure. Note that at this point not all the UAPI disintegration parts have been merged, so it is likely that more empty Kbuild files will turn up. It is probably necessary to make the files non-empty to prevent the patch program from automatically deleting them when it reduces them to nothing. Signed-off-by: David Howells <dhowells@redhat.com>
* [SCSI] FC Pass Thru supportJames Smart2009-06-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attached is the ELS/CT pass-thru patch for the FC Transport. The patch creates a generic framework that lays on top of bsg and the SGIO v4 ioctl in order to pass transaction requests to LLDD's. The interface supports the following operations: On an fc_host basis: Request login to the specified N_Port_ID, creating an fc_rport. Request logout of the specified N_Port_ID, deleting an fc_rport Send ELS request to specified N_Port_ID w/o requiring a login, and wait for ELS response. Send CT request to specified N_Port_ID and wait for CT response. Login is required, but LLDD is allowed to manage login and decide whether it stays in place after the request is satisfied. Vendor-Unique request. Allows a LLDD-specific request to be passed to the LLDD, and the passing of a response back to the application. On an fc_rport basis: Send ELS request to nport and wait for ELS response. Send CT request to nport and wait for CT response. The patch also exports several headers from include/scsi such that they can be available to user-space applications: include/scsi/scsi.h include/scsi/scsi_netlink.h include/scsi/scsi_netlink_fc.h include/scsi/scsi_bsg_fc.h For further information, refer to the last RFC: http://marc.info/?l=linux-scsi&m=123436574018579&w=2 Note: Documentation is still spotty and will be added later.

* kbuild: only one call for include/ in make headers_*Sam Ravnborg2008-07-251-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move it to the top-level file to decide if we install/check the generic headers or the arch specific headers. This revealed a long standing bug where "make headers_check_all" relied on the files in asm/ for the current architecture. So make headers_check_all is now broken by this commit. In addition: o add a simpler way to detect if an arch support exporting header files. o add 'set -e;' so we error out early if make headers_check_all fails. o add sparc64 and cris to arch we do not process in make headers_*_all because: sparc64 - use sparc to export headers cris - is know seriously broken Includes suggestions from: David Woodhouse <dwmw2@infradead.org>.

* drm: reorganise drm tree to be more future proof.Dave Airlie2008-07-141-0/+1
| | | | | | | | | | | | | | With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie <airlied@redhat.com>
