[PATCH v4 0/4] linux-user: Add syscall dispatch support

[Richard Henderson <richard.henderson@linaro.org>]

Hiya,

I have adjusted the signal return trampoline detection from

  https://lore.kernel.org/qemu-devel/20250711225226.14652-1-floss@arusekk.pl/

and tidied up a few other bits.  Would you please re-test this
versus your plan9 emulator?  Thanks,


r~
