   # HEAD: dc0a241ceaf3b7df6f1a7658b020c92682b75bfc rseq: Fix rseq registration with CONFIG_DEBUG_RSEQ

Two RSEQ fixes:

 - Fix overly spread-out RSEQ concurrency ID allocation pattern that
   regressed certain workloads.

 - Fix RSEQ registration syscall behavior on -EFAULT errors when
   CONFIG_DEBUG_RSEQ=y. (This debug option is disabled on most
   distributions.)

 Thanks,

	Ingo
