[PATCH] x86_64: Increase the maximum number of local APICs to the maximum
This is needed for large multinode IBM systems which have a sparse
APIC space in clustered mode, fully covering the available 8 bits.
The previous kernels would limit the local APIC number to 127,
which caused it to reject some of the CPUs at boot.
I increased the maximum and shrunk the apic_version array a bit
to make up for that (the version is only 8 bit, so don't need
an full int to store)
