ecbba30f - mips: syscalls: switch to generic syscalltbl.sh

Mon, 01 Mar 2021 14:48:24 +0000

mips: syscalls: switch to generic syscalltbl.shMany architectures duplicate similar shell scripts.This commit converts mips to use scripts/syscalltbl.sh. This alsounifies syscall_table_32_o32.h and syscall_table_64_o32.h intosyscall_table_o32.h.The offset parameters are unneeded here; __SYSCALL(nr, entry) is definedas 'PTR entry', so the parameter 'nr' is not used in the first place.With this commit, syscall tables and generated files are straightmapped, which makes things easier to understand. syscall_n32.tbl --> syscall_table_n32.h syscall_n64.tbl --> syscall_table_n64.h syscall_o32.tbl --> syscall_table_o32.hThen, the abi parameters are also unneeded.Signed-off-by: Masahiro Yamada Signed-off-by: Thomas Bogendoerfer List of files: /linux-6.15/arch/mips/include/asm/Kbuild

Add a new architecture specific asm/kvm_types.hto control the existence and parameters of the struct. The new headeris needed to avoid a chicken-and-egg problem with asm/kvm_host.h as allarchitectures define instances of the struct in their vCPU structs.Add an asm-generic version of kvm_types.h to avoid having empty files onPPC and s390 in the long term, and for arm64 and mips in the short term.Suggested-by: Christoffer Dall Reviewed-by: Ben Gardon Signed-off-by: Sean Christopherson Message-Id: <20200703023545.8771-15-sean.j.christopherson@intel.com>Signed-off-by: Paolo Bonzini List of files: /linux-6.15/arch/mips/include/asm/Kbuild

mips/mmiowb: Add unconditional mmiowb() to arch_spin_unlock()The mmiowb() macro is horribly difficult to use and drivers will continueto work most of the time if they omit a call when it is required.Rather than rely on driver authors getting this right, push mmiowb() intoarch_spin_unlock() for mips. If this is deemed to be a performance issue,a subsequent optimisation could make use of ARCH_HAS_MMIOWB to elidethe barrier in cases where no I/O writes were performed inside thecritical section.Acked-by: Paul Burton Acked-by: Linus Torvalds Signed-off-by: Will Deacon List of files: /linux-6.15/arch/mips/include/asm/Kbuild

MIPS: remove meaningless generic-(CONFIG_GENERIC_CSUM) += checksum.hThis line is weird in multiple ways.(CONFIG_GENERIC_CSUM) might be a typo of $(CONFIG_GENERIC_CSUM).Even if you add '$' to it, $(CONFIG_GENERIC_CSUM) is never evaluatedto 'y' because scripts/Makefile.asm-generic does not includeinclude/config/auto.conf. So, the asm-generic wrapper of checksum.his never generated.Even if you manage to generate it, it is never included by anyonebecause MIPS has the checkin header with the same file name: arch/mips/include/asm/checksum.hAs you see in the top Makefile, the checkin headers are included beforegenerated ones.
