powerpc/kvm/book3s_pr: Fix compilation on 32-bit machines
Commit a413f474 ("powerpc: Disable relocation on exceptions whenever PR KVM is active") added calls to pSeries_disable_reloc_on_exc() and pSeries_enable_reloc_on_exc() to book3s_pr.c, and added declarations of those functions to <asm/hvcall.h>, but didn't add an include of <asm/hvcall.h> to book3s_pr.c. 64-bit kernels seem to get hvcall.h included via some other path, but 32-bit kernels fail to compile with: arch/powerpc/kvm/book3s_pr.c: In function ‘kvmppc_core_init_vm’: arch/powerpc/kvm/book3s_pr.c:1300:4: error: implicit declaration of function ‘pSeries_disable_reloc_on_exc’ [-Werror=implicit-function-declaration] arch/powerpc/kvm/book3s_pr.c: In function ‘kvmppc_core_destroy_vm’: arch/powerpc/kvm/book3s_pr.c:1316:4: error: implicit declaration of function ‘pSeries_enable_reloc_on_exc’ [-Werror=implicit-function-declaration] cc1: all warnings being treated as errors make[2]: *** [arch/powerpc/kvm/book3s_pr.o] Error 1 make[1]: *** [arch/powerpc/kvm] Error 2 make: *** [sub-make] Error 2 This fixes it by adding an include of hvcall.h.
