Description Gustavo Luiz Duarte 2012-09-10 15:35:04 UTC 
Description of problem:
Firefox freezes after a few minutes of usage.
Firefox seems to be stuck, there is a LOT of messages in the strace like this:
madvise(0xfff574ce000, 4096, MADV_DONTNEED) = -1 EINVAL (Invalid argument)


Version-Release number of selected component (if applicable):
firefox-15.0-2.fc18.ppc64
xulrunner-15.0-2.fc18.ppc64


How reproducible:
A few minutes browsing random pages has been enough to reproduce the issue.

Steps to Reproduce:
1. Create a mock env for Fedora 18 for PPC64
2. Install Firefox
3. Run firefox
4. Browse a few random pages
  
Actual results:
Firefox freezes (UI stops responding and/or updating)


Expected results:
Firefox UI should continue working.

Do not decommit memory on PPC

Do not decommit memory on PPC since decommit logic assumes PageSize == ArenaSize. On PPC we have 64K page size, which is not feasible for ArenaSize. Rework of Martin's patch from https://bugzilla.mozilla.org/show_bug.cgi?id=746112

Please apply this patch to xulrunner code. This patch should fix the Firefox freezes.
