[Qemu-devel] [PATCH 0/3] target-m68k/m68k-semi: don't ignore get/put_user failure

[Peter Maydell]

This patch series cleans up the m68k semihosting support to not
ignore failure of get_user and put_user when reading semihosting
arguments and writing return values (compare f296c0d1 which did
something similar for ARM semihosting). The main motivation for
this patch is to shut up clang's complaints about 'expression
result unused'. Tested with a simple m68k hello world semihosting
binary created with the CodeSourcery coldfire toolchain:
  ~/freescale-coldfire-2011.09/bin/m68k-elf-gcc -T m5206ec3-ram-hosted.ld -o 
/tmp/hello /tmp/hello.c -lc -lcs3hosted
  ./m68k-softmmu/qemu-system-m68k -semihosting -M dummy -display none -kernel 
/tmp/hello

Meador's patch is already in qemu-trivial but I include it
here as it is a dependency.
