microblaze: Replace ASSEMBLY with ASSEMBLER in uapi headers

2025-09-12T11:12:41+00:00

__ASSEMBLY__ is only defined by the Makefile of the kernel, so this is not really useful for uapi headers (unless the userspace Makefile defines it, too). Let's switch to __ASSEMBLER__ which gets set automatically by the compiler when compiling assembly code. This is a completely mechanical patch (done with a simple "sed -i" statement).

KVM: export and iif KVM is supported

2019-03-28T16:27:42+00:00

I 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, riscv This does not match to the actual KVM support. At least, [2] is half-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-kernel build 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 support My first attempt was [A] because the code looks cleaner, but Paolo suggested [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 generated asm/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, xtensa Signed-off-by: Masahiro Yamada Acked-by: Cornelia Huck Signed-off-by: Paolo Bonzini

kbuild: force all architectures except um to include mandatory-y

2019-03-17T03:56:32+00:00

Currently, every arch/*/include/uapi/asm/Kbuild explicitly includes the common Kbuild.asm file. Factor out the duplicated include directives to scripts/Makefile.asm-generic so that no architecture would opt out of the mandatory-y mechanism. um is not forced to include mandatory-y since it is a very exceptional case which does not support UAPI.

arch: unexport asm/shmparam.h for all architectures

2019-02-01T23:46:22+00:00

Most architectures do not export shmparam.h to user-space. $ find arch -name shmparam.h | sort arch/alpha/include/asm/shmparam.h arch/arc/include/asm/shmparam.h arch/arm64/include/asm/shmparam.h arch/arm/include/asm/shmparam.h arch/csky/include/asm/shmparam.h arch/ia64/include/asm/shmparam.h arch/mips/include/asm/shmparam.h arch/nds32/include/asm/shmparam.h arch/nios2/include/asm/shmparam.h arch/parisc/include/asm/shmparam.h arch/powerpc/include/asm/shmparam.h arch/s390/include/asm/shmparam.h arch/sh/include/asm/shmparam.h arch/sparc/include/asm/shmparam.h arch/x86/include/asm/shmparam.h arch/xtensa/include/asm/shmparam.h Strangely, some users of the asm-generic wrapper export shmparam.h $ git grep 'generic-y += shmparam.h' arch/c6x/include/uapi/asm/Kbuild:generic-y += shmparam.h arch/h8300/include/uapi/asm/Kbuild:generic-y += shmparam.h arch/hexagon/include/uapi/asm/Kbuild:generic-y += shmparam.h arch/m68k/include/uapi/asm/Kbuild:generic-y += shmparam.h arch/microblaze/include/uapi/asm/Kbuild:generic-y += shmparam.h arch/openrisc/include/uapi/asm/Kbuild:generic-y += shmparam.h arch/riscv/include/asm/Kbuild:generic-y += shmparam.h arch/unicore32/include/uapi/asm/Kbuild:generic-y += shmparam.h The newly added riscv correctly creates the asm-generic wrapper in the kernel space, but the others (c6x, h8300, hexagon, m68k, microblaze, openrisc, unicore32) create the one in the uapi directory. Digging into the git history, now I guess fcc8487d477a ("uapi: export all headers under uapi directories") was the misconversion. Prior to that commit, no architecture exported to shmparam.h As its commit description said, that commit exported shmparam.h for c6x, h8300, hexagon, m68k, openrisc, unicore32. 83f0124ad81e ("microblaze: remove asm-generic wrapper headers") accidentally exported shmparam.h for microblaze. This commit unexports shmparam.h for those architectures. There is no more reason to export include/uapi/asm-generic/shmparam.h, so it has been moved to include/asm-generic/shmparam.h Link: http://lkml.kernel.org/r/1546904307-11124-1-git-send-email-yamada.masahiro@socionext.com Signed-off-by: Masahiro Yamada Acked-by: Stafford Horne Cc: Geert Uytterhoeven Cc: Michal Simek Cc: Yoshinori Sato Cc: Richard Kuo Cc: Guan Xuetao Cc: Nicolas Dichtel Cc: Arnd Bergmann Cc: Aurelien Jacquiot Cc: Greentime Hu Cc: Guo Ren Cc: Palmer Dabbelt Cc: Stefan Kristiansson Cc: Mark Salter Cc: Albert Ou Cc: Jonas Bonn Cc: Vincent Chen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

arch: restore generic-y += shmparam.h for some architectures

2019-01-07T02:16:11+00:00

For some reasons, I accidentally got rid of "generic-y += shmparam.h" from some architectures. Restore them to fix building c6x, h8300, hexagon, m68k, microblaze, openrisc, and unicore32.

arch: remove redundant UAPI generic-y defines

Now that Kbuild automatically creates asm-generic wrappers for missing mandatory headers, it is redundant to list the same headers in generic-y and mandatory-y. Suggested-by: Sam Ravnborg Signed-off-by: Masahiro Yamada Acked-by: Sam Ravnborg

arch: remove stale comments "UAPI Header export list"

2019-01-06T00:46:51+00:00

These comments are leftovers of commit fcc8487d477a ("uapi: export all headers under uapi directories"). Prior to that commit, exported headers must be explicitly added to header-y. Now, all headers under the uapi/ directories are exported. Signed-off-by: Masahiro Yamada

microblaze: generate uapi header and system call table files

2018-11-16T07:24:34+00:00

System call table generation script must be run to gener- ate unistd_32.h and syscall_table.h files. This patch will have changes which will invokes the script. This patch will generate unistd_32.h and syscall_table.h files by the syscall table generation script invoked by microblaze/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/syscall_table.S file.
