X-Git-Tag: v7.2-rc4~1 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=82a47586c0b9266622657009aa30573dddf09f53;p=thirdparty%2Fkernel%2Flinux.git Merge tag 'riscv-for-linus-7.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V fixes from Paul Walmsley: - Call flush_cache_vmap() after populating new vmemmap pages, on all architectures. This avoids spurious faults on RISC-V microarchitectures that cache PTEs marked as non-present - Disable LTO for the vDSO to prevent the compiler from eliding functions that are used, but which don't appear to be - Fix an issue with libgcc's unwinder and signal handlers by dropping an unnecessary CFI landing pad instruction in __vdso_rt_sigreturn (similar to what was done on ARM64) - Avoid reading uninitialized memory under certain conditions in hwprobe_get_cpus() - Save some memory and I$ when CONFIG_DYNAMIC_FTRACE=n by avoiding our four-byte function alignment requirement in that case - Avoid clang warnings about null-pointer arithmetic in the I/O-port accessor macros (inb, outb, etc.) by ifdeffing them out when !CONFIG_HAS_IOPORT - Make the build of the lazy TLB flushing code in the vmalloc path depend on CONFIG_64BIT and CONFIG_MMU (since those platforms are the only ones that use it) * tag 'riscv-for-linus-7.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: hwprobe: Avoid uninitialized read in hwprobe_get_cpus() arch/riscv: vdso: remove CFI landing pad from rt_sigreturn riscv: vdso: Do not use LTO for the vDSO riscv: io: avoid null-pointer arithmetic in PIO helpers riscv: Gate FUNCTION_ALIGNMENT_4B on DYNAMIC_FTRACE mm/sparse-vmemmap: flush_cache_vmap() after hotplugging vmemmap riscv: mm: Make mark_new_valid_map() stuff depend on 64BIT && MMU --- 82a47586c0b9266622657009aa30573dddf09f53
