  riscv: Handle zicsr/zifencei issue between gcc and binutils (2023-08-16 07:39:38 -0700)

----------------------------------------------------------------
RISC-V Fixes for 6.5-rc7

* A fix to avoid excessive rejections from seccomp RET_ERRNO rules.
* A fix for compressed jal/jalr decoding.
* A pair of fixes for independent irq/softirq stacks on kernels built
  with CONFIG_FRAME_POINTER=n.
* A fix to avoid a hang handling uaccess fixups.
* Another build fix for toolchain ISA strings, this time for Zicsr and
  Zifenci on old GNU toolchains.
