Hi All,

This series adds support linux-user emulation.
As the LoongArch kernel had merged into 5.19-rc1,
you can see the latest kernel at https://kernel.org

Need review patch:

  0002-linux-user-Add-LoongArch-signal-support.patch

V19:
  - Update signal.c, add fpu info, fpu_context and end info to
    target_rt_sigframe.

V18:
  - Update signal.c, add set fpu_context'magic, update parse_extcontext()
    and remove some cast.

V17:
  - Split v16 patch7 to  patch7-11, and fix some bugs for system-mode;
  - Update signal.c, add parse_extcontext();
  - Add get_elf_hwcap(), and ELF_PLATFORM.

V16:
  - Update signal.c;
  - Update helper_rdtime_d();
  - Update scripts/gensyscalls.sh, fixed a warning.

v15:
  - Rebase;
  - Update README;
  - Adjust some functions and structure to support user-mode;
  - Update syscall;
  - Update target_sigcontext;

Old series:

Test:
   make check  && make check-tcg  &&  run LoongArch bash

Thanks.
