Modified files:
sys/kern : kern_malloc.c
sys/sys : malloc.h
Log message:
The BUCKETINDX() giant macro is used to compute the base 2 logarithm of its
input, in order to pick the appropriate malloc() bucket.
Replace it with an inline function in kern_malloc.c, which will either
do a tightest-but-slower loop (if option SMALL_KERNEL), or a geometric search
equivalent to what the macro does, but producing smaller code (especially on
platforms which can not load large constants in one instruction).
