Hi all- Patch 1 is a revert, Cc'd to stable. I haven't tried to write a real test for the bug, but the code definitely looks buggy. I intent to fix it for real as part of converting more of the syscall entry code to C, but this is a better fix for now.
Patch 2 fixes selftests fallout from the sigcontext revert. Patch 3 is a new test that I thought I added but apparently didn't. It's probably 4.3 material, but it's related to patch 1, so I'm sending them together.
