In drivers/gsc/eisa_enumerator.c:
+static inline u_int16_t get_16(const unsigned char *x)
+{ 
+       return (x[1] << 8) | x[0];
+}
+
+static inline u_int32_t get_32(const unsigned char *x)
+{
+       return (x[3] << 24) | (x[2] << 16) | (x[1] << 8) | x[0];
+}

Thought this works, this generates horribly code. At least the
HPUX compiler did when I looked at it 5 years (or so) ago.
If anyone cares about EISA perf, stealing inline asm from
include/asm/byteorder.h (eg ___arch__swab32) would help.
