Before the recent "x86_64,signal: Fix SS handling for signals delivered to 64-bit programs" kernel patch, sigreturn paths forgot to restore ->ss after return from the signal handler. Now that the kernel was fixed, restore_gpregs() has to initialize ->ss too, it is no longer ignored. Note: this is the minimal fix. In the long term we probably should not dump/restore the segment registers at all. We can use sigcontext filled by the target kernel and modify the general-purpose regs.
