Merge patch series "riscv: Add GENERIC_ENTRY support"
guoren@kernel.org <guoren@kernel.org> says:
From: Guo Ren <guoren@linux.alibaba.com>
The patches convert riscv to use the generic entry infrastructure from
kernel/entry/*. Some optimization for entry.S with new .macro and merge
ret_from_kernel_thread into ret_from_fork.
* b4-shazam-merge:
riscv: entry: Consolidate general regs saving/restoring
riscv: entry: Consolidate ret_from_kernel_thread into ret_from_fork
riscv: entry: Remove extra level wrappers of trace_hardirqs_{on,off}
riscv: entry: Convert to generic entry
riscv: entry: Add noinstr to prevent instrumentation inserted
riscv: ptrace: Remove duplicate operation
