2019-09-20T15:36:47Z

Pull Kbuild updates from Masahiro Yamada: - add modpost warn exported symbols marked as 'static' because 'static' and EXPORT_SYMBOL is an odd combination - break the build early if gold linker is used - optimize the Bison rule to produce .c and .h files by a single pattern rule - handle PREEMPT_RT in the module vermagic and UTS_VERSION - warn CONFIG options leaked to the user-space except existing ones - make single targets work properly - rebuild modules when module linker scripts are updated - split the module final link stage into scripts/Makefile.modfinal - fix the missed error code in merge_config.sh - improve the error message displayed on the attempt of the O= build in unclean source tree - remove 'clean-dirs' syntax - disable -Wimplicit-fallthrough warning for Clang - add CONFIG_CC_OPTIMIZE_FOR_SIZE_O3 for ARC - remove ARCH_{CPP,A,C}FLAGS variables - add $(BASH) to run bash scripts - change *CFLAGS_.o to take the relative path to $(obj) instead of the basename - stop suppressing Clang's -Wunused-function warnings when W=1 - fix linux/export.h to avoid genksyms calculating CRC of trimmed exported symbols - misc cleanups * tag 'kbuild-v5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (63 commits) genksyms: convert to SPDX License Identifier for lex.l and parse.y modpost: use __section in the output to *.mod.c modpost: use MODULE_INFO() for __module_depends export.h, genksyms: do not make genksyms calculate CRC of trimmed symbols export.h: remove defined(__KERNEL__), which is no longer needed kbuild: allow Clang to find unused static inline functions for W=1 build kbuild: rename KBUILD_ENABLE_EXTRA_GCC_CHECKS to KBUILD_EXTRA_WARN kbuild: refactor scripts/Makefile.extrawarn merge_config.sh: ignore unwanted grep errors kbuild: change *FLAGS_.o to take the path relative to $(obj) modpost: add NOFAIL to strndup modpost: add guid_t type definition kbuild: add $(BASH) to run scripts with bash-extension kbuild: remove ARCH_{CPP,A,C}FLAGS kbuild,arc: add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3 for ARC kbuild: Do not enable -Wimplicit-fallthrough for clang for now kbuild: clean up subdir-ymn calculation in Makefile.clean kbuild: remove unneeded '+' marker from cmd_clean kbuild: remove clean-dirs syntax kbuild: check clean srctree even earlier ...

kbuild: rebuild modules when module linker scripts are updated

2019-08-21T12:05:21Z

Currently, the timestamp of module linker scripts are not checked. Add them to the dependency of modules so they are correctly rebuilt. Signed-off-by: Masahiro Yamada

ia64: remove support for machvecs

2019-08-16T21:32:26Z

The only thing remaining of the machvecs is a few checks if we are running on an SGI UV system. Replace those with the existing is_uv_system() check that has been rewritten to simply check the OEM ID directly. That leaves us with a generic kernel that is as fast as the previous DIG/ZX1/UV kernels, but can support all hardware. Support for UV and the HP SBA IOMMU is now optional based on new config options.

ia64: rework iommu probing

2019-08-16T18:33:57Z

ia64 currently organizes the iommu probing along machves, which isn't very helpful. Instead just try to probe for Intel IOMMUs in mem_init as they are properly described in ACPI and if none was found initialize the swiotlb buffer. The HP SBA handling is then only done delayed when the actual hardware is probed. Only in the case that we actually found usable IOMMUs we then set up the DMA ops and free the not needed swiotlb buffer. This scheme gets rid of the need for the dma_init machvec operation, and the dig_vtd machvec.

ia64: remove the zx1 swiotlb machvec

2019-08-16T18:33:57Z

The aim of this machvec is to support devices with < 32-bit dma masks. But given that ia64 only has a ZONE_DMA32 and not a ZONE_DMA that isn't supported by swiotlb either. Signed-off-by: Christoph Hellwig Link: https://lkml.kernel.org/r/20190813072514.23299-21-hch@lst.de Signed-off-by: Tony Luck

ia64: remove CONFIG_PCI ifdefs

2019-08-16T18:33:57Z

Now that hpsim support is gone, CONFIG_PCI is forced on for ia64, and we can remove a few ifdefs for it. Acked-by: Tom Vaden Signed-off-by: Christoph Hellwig Link: https://lkml.kernel.org/r/20190813072514.23299-19-hch@lst.de Signed-off-by: Tony Luck

ia64: remove the hpsim platform

2019-08-16T18:33:57Z

The hpsim platform supports the HP IA64 simulator which was useful as a bring up platform. But it is fairly non-standard vs real IA64 system in that it for example doesn't support ACPI. It also comes with a whole bunch of simulator specific drivers. Remove it to simplify the IA64 port. Note that through a weird twist only them hpsim boot loader built the vmlinux.gz file, so the makefile targets for that are moved to the main ia64 Makefile now.

ia64: remove support for the SGI SN2 platform

2019-08-16T18:33:57Z

The SGI SN2 (early Altix) is a very non-standard IA64 platform that was at the very high end of even IA64 hardware, and has been discontinued a long time ago. Remove it because there no upstream users left, and it has magic hooks all over the kernel.

ia64: generate uapi header and system call table files

2018-11-13T16:56:25Z

System call table generation script must be run to gener- ate unistd_64.h and syscall_table.h files. This patch will have changes which will invokes the script. This patch will generate unistd_64.h and syscall_table.h files by the syscall table generation script invoked by ia64/Makefile and the generated files against the removed files must be identical. The generated uapi header file will be included in uapi/- asm/unistd.h and generated system call table header file will be included by kernel/entry.S file.
