[cc list trimmed from the previous patches to include only people who seem like they would care about this round of changes. My apologies if I missed anyone.]
This series applies to the x86/vdso branch of the -tip tree.
Patch 1/3 deletes some very outdated comments in vsyscall_64.c.
Patch 2/3 simplifies the vsyscall emulation int 0xcc mechanism and removes some ret instructions that are (as pointed out by the PaX team) possibly dangerous.
Patch 3/3 fixes what is arguably the most serious problem of all: people thought that CONFIG_COMPAT_VSYSCALLS controlled binary compatibility. It changes the Kconfig short description, help text, and feature removal entry to make it a lot more clear what's going on.
