[PATCH] x86/process: Fix some -Wmissing-prototypes warnings

[Yi Wang]

We get a warning when building kernel with W=1:
arch/x86/kernel/process.c:653:13: warning: no previous prototype for âarch_post_acpi_subsys_initâ [-Wmissing-prototypes]
arch/x86/kernel/process.c:717:15: warning: no previous prototype for âarch_randomize_brkâ [-Wmissing-prototypes]
arch/x86/kernel/process.c:784:6: warning: no previous prototype for âdo_arch_prctl_commonâ [-Wmissing-prototypes]

Add the missing including files to fix this.
