x86: don't include slab.h from arch/x86/include/asm/pgtable_32.h
Including slab.h from x86 pgtable_32.h creates a troublesome
dependency chain w/ ftrace enabled. The following chain leads to
inclusion of pgtable_32.h from define_trace.h.
trace/define_trace.h
trace/ftrace.h
linux/ftrace_event.h
linux/ring_buffer.h
linux/mm.h
asm/pgtable.h
asm/pgtable_32.h
slab.h itself defines trace hooks via
linux/sl[aou]b_def.h
linux/kmemtrace.h
trace/events/kmem.h
If slab.h is not included before define_trace.h is included, this
leads to duplicate definitions of kmemtrace hooks or other include
dependency problems.
pgtable_32.h doesn't need slab.h to begin with. Don't include it from
there.
