[Qemu-devel] Make QEMU more friendly for kernel debug

[prime]

Hello everyone,
   I find that I can't single step OS kernels use qemu.When I use "step"
or "next" command in gdb,the kernel always enter its interrupt route 
instead of executing the next instruction after the breakpoint.So I modify
QEMU's source code to disable interrupts in single step mode,and now I
can use "step" or "next" command in gdb to single step functions.

   Should I post the patch? It is a very small modification.
