asm-generic: make more kernel-space headers mandatory

2020-04-02T16:35:25Z

Change a header to mandatory-y if both of the following are met: [1] At least one architecture (except um) specifies it as generic-y in arch/*/include/asm/Kbuild [2] Every architecture (except um) either has its own implementation (arch/*/include/asm/*.h) or specifies it as generic-y in arch/*/include/asm/Kbuild This commit was generated by the following shell script. ----------------------------------->8----------------------------------- arches=$(cd arch; ls -1 | sed -e '/Kconfig/d' -e '/um/d') tmpfile=$(mktemp) grep "^mandatory-y +=" include/asm-generic/Kbuild > $tmpfile find arch -path 'arch/*/include/asm/Kbuild' | xargs sed -n 's/^generic-y += $.*$/\1/p' | sort -u | while read header do mandatory=yes for arch in $arches do if ! grep -q "generic-y += $header" arch/$arch/include/asm/Kbuild && ! [ -f arch/$arch/include/asm/$header ]; then mandatory=no break fi done if [ "$mandatory" = yes ]; then echo "mandatory-y += $header" >> $tmpfile for arch in $arches do sed -i "/generic-y += $header/d" arch/$arch/include/asm/Kbuild done fi done sed -i '/^mandatory-y +=/d' include/asm-generic/Kbuild LANG=C sort $tmpfile >> include/asm-generic/Kbuild ----------------------------------->8----------------------------------- One obvious benefit is the diff stat: 25 files changed, 52 insertions(+), 557 deletions(-) It is tedious to list generic-y for each arch that needs it. So, mandatory-y works like a fallback default (by just wrapping asm-generic one) when arch does not have a specific header implementation. See the following commits: def3f7cefe4e81c296090e1722a76551142c227c a1b39bae16a62ce4aae02d958224f19316d98b24 It is tedious to convert headers one by one, so I processed by a shell script.

asm-generic: Make dma-contiguous.h a mandatory include/asm header

2020-02-04T10:38:59Z

dma-continuguous.h is generic for all architectures except arm32 which has its own version. Similar change was done for msi.h by commit a1b39bae16a6 ("asm-generic: Make msi.h a mandatory include/asm header") Suggested-by: Christoph Hellwig Link: https://lore.kernel.org/linux-arm-kernel/20200117080446.GA8980@lst.de/T/#m92bb56b04161057635d4142e1b3b9b6b0a70122e Signed-off-by: Michal Simek Reviewed-by: Christoph Hellwig Acked-by: Thomas Gleixner Acked-by: Arnd Bergmann Acked-by: Paul Walmsley # for arch/riscv

asm-generic: Make msi.h a mandatory include/asm header

2019-11-26T19:14:11Z

msi.h is generic for all architectures except x86, which has its own version. Enabling MSI by adding msi.h to every architecture's Kbuild is just an additional step which doesn't need to be done. Make msi.h mandatory in the asm-generic/Kbuild so we don't have to do it for each architecture.

riscv: include generic support for MSI irqdomains

2019-07-22T20:06:07Z

Some RISC-V systems include PCIe host controllers that support PCIe message-signaled interrupts. For this to work on Linux, we need to enable PCI_MSI_IRQ_DOMAIN and define struct msi_alloc_info. Support for the latter is enabled by including the architecture-generic msi.h include.

riscv: remove redundant kernel-space generic-y

2019-01-06T00:46:51Z

This commit removes redundant generic-y defines in arch/riscv/include/asm/Kbuild. [1] It is redundant to define the same generic-y in both arch/$(ARCH)/include/asm/Kbuild and arch/$(ARCH)/include/uapi/asm/Kbuild. Remove the following generic-y: errno.h fcntl.h ioctl.h ioctls.h ipcbuf.h mman.h msgbuf.h param.h poll.h posix_types.h resource.h sembuf.h setup.h shmbuf.h signal.h socket.h sockios.h stat.h statfs.h swab.h termbits.h termios.h types.h [2] It is redundant to define generic-y when arch-specific implementation exists in arch/$(ARCH)/include/asm/*.h Remove the following generic-y: cacheflush.h module.h Signed-off-by: Masahiro Yamada
