[PATCH 03/12] x86/ftrace: Explicitly include vmalloc.h for set_vm_flush_reset_perms()

[Sean Christopherson]

The inclusion of linux/vmalloc.h, which is required for its definition
of set_vm_flush_reset_perms(), is somehow dependent on asm/realmode.h
being included by asm/acpi.h.  Explicitly include linux/vmalloc.h so
that a future patch can drop the realmode.h include from asm/acpi.h
without breaking the build.

Fixes: 7fdfe1e40b225 ("x86/ftrace: Use vmalloc special flag")
