[Qemu-devel] [PATCH 3/5] user-exec: Delete now-unused hppa and m68k cpu_signal_handler() code |
Date: |
Tue, 14 Jun 2016 10:52:05 +0100 |
Now that configure blocks attempts to build user-mode code on hppa
and m68k hosts, we can delete the cpu_signal_handler() implementations
for those architectures.
