sparc32: probe for cpu info only during startup
We did a cpu_probe() call each time a CPU got online - which
only effect was to save latest CPU/FPU info for use by show_cpuinfo().
Use same setup as for sparc64 where we probe for this info during startup,
and only once.
This allowed us to annotate a few functions __init which again
fixed the following section mismatch warnings:
WARNING: vmlinux.o(.text+0x65f0): Section mismatch in reference from the function set_cpu_and_fpu() to the (unknown reference) .init.rodata:(unknown)
WARNING: vmlinux.o(.text+0x65f8): Section mismatch in reference from the function set_cpu_and_fpu() to the (unknown reference) .init.rodata:(unknown)
WARNING: vmlinux.o(.text+0x664c): Section mismatch in reference from the function set_cpu_and_fpu() to the variable .init.rodata:manufacturer_info
WARNING: vmlinux.o(.text+0x6650): Section mismatch in reference from the function set_cpu_and_fpu() to the variable .init.rodata:manufacturer_info
