Merge tag 'riscv-for-linus-4.21-rc2-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux
Pull RISC-V updates from Palmer Dabbelt: "This tag contains a handful of updates that slipped through the cracks during the merge window due to the holidays. The fixes are mostly independent, with the exception of one larger audit-related branch. Core RISC-V updates: - The BSS has been moved, which shrinks flat images. - A fix to test-bpf so it compiles on RV64I-based systems. - A fix to respect the kernel commandline when there is no device tree. - A fix to prevent CPUs from trying to put themselves to sleep when bringing down the system. - Support for MODULE_SECTIONS on RV32I-based systems. - [new in v2] The addition of an SBI earlycon driver. This is definately a new feature, but I'd like to include it now because I dropped this patch when submitting the merge window PR that removed our EARLY_PRINTK support. RISC-V audit updates: - The addition of NR_syscalls into unistd.h, which is necessary for CONFIG_FTRACE_SYSCALLS. - The definition of CREATE_TRACE_POINTS so __tracepoint_sys_{enter,exit} get defined. - A fix for trace_sys_exit() so we can enable HAVE_SYSCALL_TRACEPOINTS As usual, I've tested this by booting a Fedora-based image on a recent QEMU (this time just whatever I had lying around). * tag 'riscv-for-linus-4.21-rc2-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux: tty/serial: Add RISC-V SBI earlycon support riscv: add HAVE_SYSCALL_TRACEPOINTS to Kconfig riscv: fix trace_sys_exit hook riscv: define CREATE_TRACE_POINTS in ptrace.c riscv: define NR_syscalls in unistd.h riscv: audit: add audit hook in do_syscall_trace_enter/exit() riscv: add audit support RISC-V: Support MODULE_SECTIONS mechanism on RV32 MAINTAINERS: SiFive drivers: add myself as a SiFive driver maintainer MAINTAINERS: SiFive drivers: change the git tree to a SiFive git tree riscv: don't stop itself in smp_send_stop arch: riscv: support kernel command line forcing when no DTB passed tools uapi: fix RISC-V 64-bit support RISC-V: Make BSS section as the last section in vmlinux.lds.S
