[Qemu-devel] [PATCH v2 000/108] linux-user: Split do_syscall

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

* Changed the table into a switch, for the reason documented.
  Use macros to actually enter the syscall into the switch.
* Finish the split.
* Fix some bugs along the way.

I know it's a huge patch set, but I guess it was always going
to be in order to finish -- it was a stupidly large function.
