[PATCH] Include asm/vsyscall.h in arch/x86/kernel/alternative.c.

[Doug Whitesell (LKML)]

The VSYSCALL_START and VSYSCALL_END symbols are referenced in
apply_alternatives(), but vsyscall.h is not always included when
building on x86-64 with random configurations. Including asm/vsyscall.h
guarantees availability of the symbols, and is otherwise harmless.
