a13408c2 - char/agp: introduce asm-generic/agp.h

Sun, 12 Feb 2023 08:46:11 +0000

char/agp: introduce asm-generic/agp.hThere are several architectures that duplicate definitions ofmap_page_into_agp(), unmap_page_from_agp() and flush_agp_cache().Define those in asm-generic/agp.h and use it instead of duplicatedper-architecture headers.Signed-off-by: Mike Rapoport (IBM) Signed-off-by: Arnd Bergmann List of files: /linux-6.15/arch/parisc/include/asm/Kbuild

630f289b - asm-generic: make more kernel-space headers mandatory

Thu, 02 Apr 2020 04:03:12 +0000

asm-generic: make more kernel-space headers mandatoryChange 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/KbuildThis 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 > $tmpfilefind arch -path 'arch/*/include/asm/Kbuild' | xargs sed -n 's/^generic-y += $.*$/\1/p' | sort -u |while read headerdo mandatory=yes for arch in $arches do if ! grep -q "generic-y += $header" arch/$arch/include/asm/Kbuild && !

3d9683cf - KVM: export and iif KVM is supported

KVM: export and iif KVM is supportedI do not see any consistency about headers_install of and .According to my analysis of Linux 5.1-rc1, there are 3 groups: [1] Both and are exported alpha, arm, hexagon, mips, powerpc, s390, sparc, x86 [2] is exported, but is not arc, arm64, c6x, h8300, ia64, m68k, microblaze, nios2, openrisc, parisc, sh, unicore32, xtensa [3] Neither nor is exported csky, nds32, riscvThis does not match to the actual KVM support. At least, [2] ishalf-baked.Nor do arch maintainers look like they care about this. For example,commit 0add53713b1c ("microblaze: Add missing kvm_para.h to Kbuild")exported to user-space in order to fix an in-kernelbuild error.We have two ways to make this consistent: [A] export both and for all architectures, irrespective of the KVM support [B] Match the header export of and to the KVM supportMy first attempt was [A] because the code looks cleaner, but Paolosuggested [B].So, this commit goes with [B].For most architectures, was moved to the kernel-space.I changed include/uapi/linux/Kbuild so that it checks generatedasm/kvm_para.h as well as check-in ones.After this commit, there will be two groups: [1] Both and are exported arm, arm64, mips, powerpc, s390, x86 [2] Neither nor is exported alpha, arc, c6x, csky, h8300, hexagon, ia64, m68k, microblaze, nds32, nios2, openrisc, parisc, riscv, sh, sparc, unicore32, xtensaSigned-off-by: Masahiro Yamada Acked-by: Cornelia Huck Signed-off-by: Paolo Bonzini List of files: /linux-6.15/arch/parisc/include/asm/Kbuild

bd78acad - parisc: move generic-y of exported headers to uapi/asm/Kbuild

Sun, 09 Jul 2017 18:32:52 +0000

parisc: move generic-y of exported headers to uapi/asm/KbuildSince commit fcc8487d477a ("uapi: export all headers under uapidirectories"), all (and only) headers under uapi directories areexported, but asm-generic wrappers are still exceptions.To complete de-coupling the uapi from kernel headers, move generic-yof exported headers to uapi/asm/Kbuild.With this change, "make headers_install" will just need to parseuapi/asm/Kbuild to build up exported headers.Also, move "generic-y += kprobes.h" up in order to keep the entriessorted.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/parisc/include/asm/Kbuild

7d134b2c - kprobes: move kprobe declarations to asm-generic/kprobes.h

Mon, 27 Feb 2017 22:26:56 +0000

kprobes: move kprobe declarations to asm-generic/kprobes.hOften all is needed is these small helpers, instead of compiler.h or afull kprobes.h. This is important for asm helpers, in fact even someasm/kprobes.h make use of these helpers... instead just keep a genericasm file with helpers useful for asm code with the least amount ofclutter as possible.Likewise we need now to also address what to do about this file for bothwhen architectures have CONFIG_HAVE_KPROBES, and when they do not. Thenfor when architectures have CONFIG_HAVE_KPROBES but have disabledCONFIG_KPROBES.Right now most asm/kprobes.h do not have guards against CONFIG_KPROBES,this means most architecture code cannot include asm/kprobes.h safely.Correct this and add guards for architectures missing them.Additionally provide architectures that not have kprobes support withthe default asm-generic solution. This lets us force asm/kprobes.h onthe header include/linux/kprobes.h always, but most importantly we cannow safely include just asm/kprobes.h on architecture code withoutbringing the full kitchen sink of header files.Two architectures already provided a guard against CONFIG_KPROBES on itskprobes.h: sh, arch. The rest of the architectures needed gaurds added.We avoid including any not-needed headers on asm/kprobes.h unlesskprobes have been enabled.In a subsequent atomic change we can try now to remove compiler.h frominclude/linux/kprobes.h.During this sweep I've also identified a few architectures defining acommon macro needed for both kprobes and ftrace, that of the definitionof the breakput instruction up. Some refer to this asBREAKPOINT_INSTRUCTION. This must be kept outside of the #ifdefCONFIG_KPROBES guard.[mcgrof@kernel.org: fix arm64 build] Link: http://lkml.kernel.org/r/CAB=NE6X1WMByuARS4mZ1g9+W=LuVBnMDnh_5zyN0CLADaVh=Jw@mail.gmail.com[sfr@canb.auug.org.au: fixup for kprobes declarations moving] Link: http://lkml.kernel.org/r/20170214165933.13ebd4f4@canb.auug.org.auLink: http://lkml.kernel.org/r/20170203233139.32682-1-mcgrof@kernel.orgSigned-off-by: Luis R.
