It builds, and I made sure that USE_IMMEDIATE does get defined by the makefile changes you made.
On the other hand, CONFIG_PSRWLOCK_LATENCY_TEST fails to build:
CC lib/psrwlock-latency-trace.o lib/psrwlock-latency-trace.c: In function ‘calibrate_get_cycles’: lib/psrwlock-latency-trace.c:60: error: implicit declaration of function ‘rdtsc_barrier’
You could use sched_clock() or similar, we do have portable interfaces by which to do these things. And if we don't have something fitting exactly what is needed here, add it :-)
Also:
<stdin>:1421:2: warning: #warning syscall marker not implemented <stdin>:1425:2: warning: #warning syscall trace not implemented
which should be fixed by the following patch:
sparc: Add sys_trace() and sys_marker() syscall table entries.
