Subject: [ 024/117] KVM: PPC: Book3S: Fix compile error in XICS emulation

3.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Paul Mackerras <paulus@...ba.org>

commit 7bfa9ad55d691f2b836b576769b11eca2cf50816 upstream.

Commit 8e44ddc3f3 ("powerpc/kvm/book3s: Add support for H_IPOLL and
H_XIRR_X in XICS emulation") added a call to get_tb() but didn't
include the header that defines it, and on some configs this means
book3s_xics.c fails to compile:

arch/powerpc/kvm/book3s_xics.c: In function ‘kvmppc_xics_hcall’:
arch/powerpc/kvm/book3s_xics.c:812:3: error: implicit declaration of function ‘get_tb’ [-Werror=implicit-function-declaration]
