building native JDK 1.5.0 and linprocfs witness reports

[Yuri Pankov]

Hi.

I've problems compiling native JDK 1.5.0. Posting to this list as it
seems related to linprocfs problems (linux-sun-jdk is used for
bootstraping). Build fails early in the beginning with "javac"
segmentation fault, and here's what I get in dmesg (lots of such
messages):
malloc(M_WAITOK) of "1024", forcing M_NOWAIT with the
following non-sleepable locks held: exclusive sleep mutex vm object
(standard object) r = 0 (0xffffff0063434578) locked
@ /usr/src/sys/compat/linprocfs/linprocfs.c:835

running recent -CURRENT/amd64. COMPAT_43TTY, COMPAT_LINUX32 and
LINPROCFS are compiled in kernel.
