Subject: target/ppc: Prohibit target specific KVM prototypes on user emulation
X-Git-Tag: v8.2.0-rc0~19^2~40
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c6b8252c6d55a4db19a67c295f88b66158c6d94e;p=thirdparty%2Fqemu.git

target/ppc: Prohibit target specific KVM prototypes on user emulation

None of these target-specific prototypes should be used
by user emulation. Remove their declaration there, so we
get a compile failure if ever used (instead of having to
deal with linker and its possible optimizations, such
dead code removal).
