Michael Ellerman ffed15d3ce powerpc/kernel: Fix size of NUM_CPU_FTR_KEYS on 32-bit 
The number of CPU feature keys is meant to map 1:1 to the number of CPU
feature flags defined in cputable.h, and the latter must fit in an
unsigned long.

In commit 4db7327194db ("powerpc: Add option to use jump label for
cpu_has_feature()"), I incorrectly defined NUM_CPU_FTR_KEYS to 64.

There should be no real adverse consequences of this bug, other than us
allocating too many keys.

Fix it by using BITS_PER_LONG.

Fixes: 4db7327194db ("powerpc: Add option to use jump label for cpu_has_feature()")
