From: Roland McGrath Date: Wed, 30 Jan 2008 12:30:55 +0000 (+0100) Subject: x86: PTRACE_SINGLEBLOCK X-Git-Tag: upstream/snapshot3+hdmi~28324^2~685 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0fa376e027f0bd71368e1485f863f0dff8f7c897;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git x86: PTRACE_SINGLEBLOCK This adds the PTRACE_SINGLEBLOCK request on x86, matching the ia64 feature. The implementation comes from the generic ptrace code and relies on the low-level machine support provided by arch_has_block_step() et al.
