Subject: 4.0 parisc regression: memory leak?

I noticed that with 4.0 I'm running out of memory on HP A500 (1G RAM)
and HP RP3410 (2G RAM) parisc machines during gentoo "revdep-rebuild
-ip". Each time free shows less free memory until OOM killer visits us
(and first revdep-rebuild after nontrivial emerge compilation loop kills
the smaller box).

3.19 did not seem to have this problem.

Nothing in the dmesg besides OOM killer activating.

I reran it, leaving cat /prov/vmstat, cat /proc/meminfo and slabtop -o
running in loop (each 5 s). revdep-rebuild -ip was also running in
the loop, just checking the binaries and library linking info.

The results are at

http://kodu.ut.ee/~mroos/slabtop-log
http://kodu.ut.ee/~mroos/meminfo-log
http://kodu.ut.ee/~mroos/vmstat-log

Anything else I can provide to pinpoint it?

I've also had problems with 4.0. I had HPMC after a few hours on rp3440.

My rp3440 worked fine for emerge world - maybe an hour or some hours.
Because of 12G RAM, it did not run out of memory.
