treewide: add "WITH Linux-syscall-note" to SPDX tag of uapi headers

2019-07-25T09:05:10Z

UAPI headers licensed under GPL are supposed to have exception "WITH Linux-syscall-note" so that they can be included into non-GPL user space application code. The exception note is missing in some UAPI headers. Some of them slipped in by the treewide conversion commit b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license"). Just run: $ git show --oneline b24413180f56 -- arch/x86/include/uapi/asm/ I believe they are not intentional, and should be fixed too. This patch was generated by the following script: git grep -l --not -e Linux-syscall-note --and -e SPDX-License-Identifier \ -- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild | while read file do sed -i -e '/[[:space:]]OR[[:space:]]/s/$GPL-[^[:space:]]*$/(\1 WITH Linux-syscall-note)/g' \ -e '/[[:space:]]or[[:space:]]/s/$GPL-[^[:space:]]*$/(\1 WITH Linux-syscall-note)/g' \ -e '/[[:space:]]OR[[:space:]]/!{/[[:space:]]or[[:space:]]/!s/$GPL-[^[:space:]]*$/\1 WITH Linux-syscall-note/g}' $file done After this patch is applied, there are 5 UAPI headers that do not contain "WITH Linux-syscall-note". They are kept untouched since this exception applies only to GPL variants. $ git grep --not -e Linux-syscall-note --and -e SPDX-License-Identifier \ -- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild include/uapi/drm/panfrost_drm.h:/* SPDX-License-Identifier: MIT */ include/uapi/linux/batman_adv.h:/* SPDX-License-Identifier: MIT */ include/uapi/linux/qemu_fw_cfg.h:/* SPDX-License-Identifier: BSD-3-Clause */ include/uapi/linux/vbox_err.h:/* SPDX-License-Identifier: MIT */ include/uapi/linux/virtio_iommu.h:/* SPDX-License-Identifier: BSD-3-Clause */ Signed-off-by: Masahiro Yamada Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

Pull asm-generic updates from Arnd Bergmann: "The asm-generic changes for 5.3 consist of a cleanup series to remove ptrace.h from Christoph Hellwig, who explains: 'asm-generic/ptrace.h is a little weird in that it doesn't actually implement any functionality, but it provided multiple layers of macros that just implement trivial inline functions. We implement those directly in the few architectures and be off with a much simpler design.' at https://lore.kernel.org/lkml/20190624054728.30966-1-hch@lst.de/" * tag 'asm-generic-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: asm-generic: remove ptrace.h x86: don't use asm-generic/ptrace.h sh: don't use asm-generic/ptrace.h powerpc: don't use asm-generic/ptrace.h arm64: don't use asm-generic/ptrace.h

The sh code is mostly equivalent to the generic one, minus various bugfixes and two arch overrides that this patch adds to pgtable.h.

sh: prevent warnings when using iounmap

2019-07-12T18:05:41Z

When building drm/exynos for sh, as part of an allmodconfig build, the following warning triggered: exynos7_drm_decon.c: In function `decon_remove': exynos7_drm_decon.c:769:24: warning: unused variable `ctx' struct decon_context *ctx = dev_get_drvdata(&pdev->dev); The ctx variable is only used as argument to iounmap(). In sh - allmodconfig CONFIG_MMU is not defined so it ended up in: \#define __iounmap(addr) do { } while (0) \#define iounmap __iounmap Fix the warning by introducing a static inline function for iounmap. This is similar to several other architectures.

Doing the indirection through macros for the regs accessors just makes them harder to read, so implement the helpers directly. Note that only the helpers actually used are implemented now. Signed-off-by: Christoph Hellwig Signed-off-by: Arnd Bergmann
