Ingo Molnar 552b8aa4d1 Revert "x86: signal: change type of paramter for sys_rt_sigreturn()" ... This reverts commit 4217458daf. Justin Madru bisected this commit, it was causing weird Firefox crashes. The reason is that GCC mis-optimizes (re-uses) the on-stack parameters of the calling frame, which corrupts the syscall return pt_regs state and thus corrupts user-space register state. So we go back to the slightly less clean but more optimization-safe method of getting to pt_regs. Also add a comment to explain this.
