Subject: [PATCH v2 0/6] Collected vdso/vsyscall fixes for 3.1
Date: Wed, 3 Aug 2011 09:31:48 -0400 [thread overview]
Message-ID: <cover.1312378163.git.luto@mit.edu> (raw)
This fixes various problems that cropped up with the vdso patches.
- Patch 1 fixes an information leak to userspace.
- Patches 2 and 3 fix the kernel build on gold.
- Patches 4 and 5 fix Xen (I hope).
- Patch 6 (optional) adds a trace event to vsyscall emulation. It will
make it easier to handle performance regression reports :)

Changes from v1:
- Improve changelog message for "x86-64/xen: Enable the vvar mapping"
- Fix 32-bit build.
- Add patch 6.
