0c3beacf - asm-generic: introduce text-patching.h

Wed, 23 Oct 2024 16:27:06 +0000

asm-generic: introduce text-patching.hSeveral architectures support text patching, but they name the headerfiles that declare patching functions differently.Make all such headers consistently named text-patching.h and add an emptyheader in asm-generic for architectures that do not support text patching.Link: https://lkml.kernel.org/r/20241023162711.2579610-4-rppt@kernel.orgSigned-off-by: Mike Rapoport (Microsoft) Reviewed-by: Christoph Hellwig Acked-by: Geert Uytterhoeven # m68kAcked-by: Arnd Bergmann Reviewed-by: Luis Chamberlain Tested-by: kdevops Cc: Andreas Larsson Cc: Andy Lutomirski Cc: Ard Biesheuvel Cc: Borislav Petkov (AMD) Cc: Brian Cain Cc: Catalin Marinas Cc: Christophe Leroy Cc: Dave Hansen Cc: Dinh Nguyen Cc: Guo Ren Cc: Helge Deller Cc: Huacai Chen Cc: Ingo Molnar Cc: Johannes Berg Cc: John Paul Adrian Glaubitz Cc: Kent Overstreet Cc: Liam R.

77122bf9 - openrisc: convert to generic syscall table

Tue, 23 Apr 2024 21:14:14 +0000

openrisc: convert to generic syscall tableThe uapi/asm/unistd_32.h and asm/syscall_table_32.h headers can now begenerated from scripts/syscall.tbl, which makes this consistent withthe other architectures that have their own syscall.tbl.openrisc has one extra system call that gets added to scripts/syscall.tbl.The time32, stat64, rlimit and renameat entries in the syscall_abis_32line are for system calls that were part of the generic ABI whenarch/nios2 got added but are no longer enabled by default for newarchitectures.Both the user visible side of asm/unistd.h and the internal syscalltable in the kernel should have the same effective contents after this.When asm/syscalls.h is included in kernel/fork.c for the purpose oftype checking, the redirection macros cause problems. Move these soonly the references get redirected.Signed-off-by: Arnd Bergmann List of files: /linux-6.15/arch/openrisc/include/asm/Kbuild

ded2ee36 - openrisc: Add pci bus support

Sat, 11 Jun 2022 23:42:33 +0000

openrisc: Add pci bus supportThis patch adds required definitions to allow for PCI buses on OpenRISC.This is being tested on the OpenRISC QEMU virt platform which is indevelopment.OpenRISC does not have IO ports so we keep the definition ofIO_SPACE_LIMIT and PIO_RESERVED to be 0.Note, since commit 66bcd06099bb ("parport_pc: Also enable driver for PCIsystems") all platforms that support PCI also need to support parallelport. We add a generic header to support compiling parallel portdrivers, though they generally will not work as they require IO ports.Signed-off-by: Stafford Horne List of files: /linux-6.15/arch/openrisc/include/asm/Kbuild

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/openrisc/include/asm/Kbuild

Those should generally use thehigher-level linux/compat.h file, but that in turn fails to includeasm/compat.h when CONFIG_COMPAT is disabled, unless we can providethat header on all architectures.This adds the asm/compat.h for all remaining architectures tosimplify the dependencies.Architectures that are getting removed in linux-4.17 are not changedhere, to avoid needless conflicts with the removal patches.

This patch fixes the issue to ensure icacheis properly synchronized when code is written to memory. It supports bothSMP and UP flushing.This supports dcache flush as well for architectures that do not supportwrite-through caches; most OpenRISC implementations do implementwrite-through cache however.
