| * scripts/gdb: add lx-fdtdump commandPeter Griffin2017-04-052-0/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lx-fdtdump dumps the flattened device tree passed to the kernel from the bootloader to the filename specified as the command argument. If no argument is provided it defaults to fdtdump.dtb. This then allows further post processing on the machine running GDB. The fdt header is also also printed in the GDB console. For example: (gdb) lx-fdtdump fdt_magic: 0xD00DFEED fdt_totalsize: 0xC108 off_dt_struct: 0x38 off_dt_strings: 0x3804 off_mem_rsvmap: 0x28 version: 17 last_comp_version: 16 Dumped fdt to fdtdump.dtb >fdtdump fdtdump.dtb | less This command is useful as the bootloader can often re-write parts of the device tree, and this can sometimes cause the kernel to not boot.

| * checkpatch: allow space leading blank lines in email headersJoe Perches2017-04-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow a leading space and otherwise blank link in the email headers as it can be a line wrapped Spamassassin multiple line string or any other valid rfc 2822/5322 email header. The line with space causes checkpatch to erroniously think that it's in the content body, as opposed to headers and thus flag a mail header as an unwrapped long comment line.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing behavior relies on patch context to identify function declarations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding a hook into free_reserve_area() that informs ftrace that boot up init text is being free, lets ftrace safely remove those init functions from its records, which keeps ftrace from trying to modify text that no longer exists. Note, this still does not allow for tracing .init text of modules, as modules require different work for freeing its init code.

Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit. The existing semantic patch for mode object reference count conversion is extended for these new helpers.

Now all files/directories under arch/<arch>/include/uapi/ are exported. The only change for userland is the layout of the command 'make headers_install_all': directories asm-<arch> are replaced by arch-<arch>/. Those new directories contains all files/directories of the specified arch. Note that only cris and tile have more directories than only asm: - arch-v[10|32] for cris; - arch for tile.

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-avr32/kvm_para.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/auto_dev-ioctl.h linux/bcache.h linux/btrfs_tree.h linux/cifs/cifs_mount.h linux/coresight-stm.h linux/crypto.h linux/cryptouser.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/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/userio.h linux/virtio_mmio.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).

This makes comparing object files with these options harder to do. Let's strip out the debug info and drop the __bug_table here so that we don't see false positives. There may be other things to drop later, and it may be architecture specific, but this works for me with my ARM64 build.
