This commit was created with scripts/clean-includes: ./scripts/clean-includes --git include include/*/*.h include/*/*/*.h All .c should include qemu/osdep.h first. The script performs three related cleanups: * Ensure .c files include qemu/osdep.h first. * Including it in a .h is redundant, since the .c already includes it. Drop such inclusions. * Likewise, including headers qemu/osdep.h includes is redundant. Drop these, too.
