PATCH 1/1 sparc32: small smp cleanup

From: Krzysztof Helt ([email protected])

It moves the smp_procesors_ready variable to sun4d_smp.c only.

Signed-off-by Krzysztof Helt ([email protected])

smp_processors_ready is not really used in sun4m_smp.c. Let the sun4d guys remove it.

I tested it on SS20 and 2.6.18-rc4 kernel.

Applied, except I added "static" to the instance you left in sun4d_smp.c
