Dmitry Safonov dd6736bd24 compel/x86/compat: pack ucontext_ia32 
As I've united k_rtsigset_t between native and compat ucontext's,
it's 8-bytes aligned now. We don't care about align of this as
we fill it always with memcpy()/memset(0).
So after those changes, ucontext_ia32 has received new padding
between uc_mcontext and uc_sigmask (4 bytes to align to 8-byte sized
sigmask). Because of this, mask of blocked signals was restored
with shift (wrongly).
Fixes: signalfd00, file_attr tests.

travis-ci: success for 32-bit tests fixes

CRIU (Checkpoint and Restore in Userspace)

An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.

The project home is at http://criu.org.
