When transferring to IRQ5 from an exception, save SYSCFG in memory across the
transfer and clear the trace bit.

When we get a single step exception, check whether we can safely clear the
trace bit in SYSCFG.  We can (and should) clear it after the first instruction
of the interrupt handler; the first insn saves SYSCFG to the stack in all
handlers.

Fix allmodconfig build bug introduced in latest -git by commit
7c91f062 ("V4L/DVB(7767): Move tuners to common/tuners"):

  LD      kernel/built-in.o
  LD      drivers/built-in.o
  ld: drivers/media/built-in.o: No such file: No such file or directory

which happens if all media drivers are modular:

  http://redhat.com/~mingo/misc/config-Wed_Apr_30_09_24_48_CEST_2008.bad

In that case there's no obj-y rule connecting all the built-in.o files and
the link tree breaks.

The fix is to add a guaranteed obj-y rule for the core vmlinux to build.
(which results in an empty object file if all media drivers are modular)

Due to a merge conflict, the sched_relax_domain_level control file was marked
as being handled by cpuset_read/write_u64, but the code to handle it was
actually in cpuset_common_file_read/write.

Since the value being written/read is in fact a signed integer, it should be
treated as such; this patch adds cpuset_read/write_s64 functions, and uses
them to handle the sched_relax_domain_level file.

With this patch, the sched_relax_domain_level can be read and written, and the
correct contents seen/updated.

The conversion between virtual and real time is as follows:

  dvt = rw/w * dt <=> dt = w/rw * dvt

Since we want the fair sleeper granularity to be in real time, we actually
need to do:

  dvt = - rw/w * l
