[Qemu-devel] [PATCH] #include cleanliness

[Qemu-devel] [PATCH] #include cleanliness

[Avi Kivity]

My mother always told me to explicitly #include any headers need to compile
a file, instead of relying on other #includes to bring them in.  This patch
fixes up targphys.h and cpu-common.h in this regard.

Can some qemu maintainer review this patch?  Stefan?

qemu-common.h should include stdbool.

The idea behind qemu-common.h is to avoid direct includes to help with 
portability.

Okay.  But note qemu-common.h #includes cpu.h #includes qemu-common.h...

I think osdep.h matches the "help with portability" label better, no?

Fortunately, guards will prevent infinite recursion here :-)

I don't disagree, but that's not the purpose of osdep.h today. 
qemu-common.h is a header file that's more or less supposed to be 
included by everything.

It should prevent explicit #include's for system headers.
