C6X: remove dead code from entry.S

2012-03-16T13:27:57+00:00

The ENDPROC() on sys_fadvise64_c6x() in arch/c6x/kernel/entry.S is
outside of the conditional block with the matching ENTRY() macro. This
leads a newer (v2.22 vs. v2.20) assembler to complain:

  /tmp/ccGZBaPT.s: Assembler messages:
  /tmp/ccGZBaPT.s: Error: .size expression for sys_fadvise64_c6x does not evaluate to a constant

The conditional block became dead code when c6x switched to generic
unistd.h and should be removed along with the offending ENDPROC().

C6X: add register_cpu call

2012-01-08T20:13:10+00:00

Commit ccbc60d3e19a1b6ae66ca0d89b3da02dde62088b requires CPU
topology information even in !SMP cases. This requires C6X to
add a call tp register_cpu() in order to avoid a panic at
boot time.
