>Description:
The sparc64 KGDB support asks for a cpuinfo struct and for CPUFLG_PAUSED at lines 226 and 227 when MULTIPROCESSOR is set:
#ifdef MULTIPROCESSOR
.....
    while (cpuinfo.flags & CPUFLG_PAUSED)
        cpuinfo.cache_flush((caddr_t)&cpuinfo.flags, sizeof(cpuinfo.flags));
...
#endif

But cpuinfo and CPUFLG_PAUSED are undeclared (GCC OUTPUT):
/usr/src/sys/arch/sparc64/sparc64/kgdb_machdep.c: In function `kgdb_suspend':
/usr/src/sys/arch/sparc64/sparc64/kgdb_machdep.c:226: error: `cpuinfo' undeclared (first use in this function)
/usr/src/sys/arch/sparc64/sparc64/kgdb_machdep.c:226: error: (Each undeclared identifier is reported only once
/usr/src/sys/arch/sparc64/sparc64/kgdb_machdep.c:226: error: for each function it appears in.)
/usr/src/sys/arch/sparc64/sparc64/kgdb_machdep.c:226: error: `CPUFLG_PAUSED' undeclared (first use in this function)

>How-To-Repeat:
Uncomment these lines in sys/arch/sparc64/conf/GENERIC32:
options         KGDB                    # support for kernel gdb
options         KGDB_DEVNAME="\"sab\""  # driver name for the kgdb serial chip
options         KGDB_DEVADDR=0x400000   # physical address of the chip
options         KGDB_DEVPORT=1          # port b
options         KGDB_DEVRATE=38400      # baud rate


Next, compile the kernel with: ./build -m sparc64 kernel=GENERIC.MP in your src directory.
