[Qemu-devel] [PULL 41/52] mips: Tweak location of ';' in macros

[Paolo Bonzini <pbonzini@redhat.com>]

From: Eric Blake <eblake@redhat.com>

It is more typical to provide the ';' by the caller of a macro
than to embed it in the macro itself; this is because syntax
highlight engines can get confused if a macro is called without
a semicolon before the closing '}'.
