Hi,
The first two patches probably ought to go in x86/urgent, the rest (!RFC) can
go into x86/core and wait a bit.
handle_debug() is a mess, and now that we have separate user and kernel paths,
try and clean it up a bit.
There's two RFC patches at the end that impact the ptrace_{get,set}_debugreg(6)
ABI, I've no idea what, if anything, is expected of that or if anybody actually
cares about that. If I read the code correctly nothing actually consumes the
value from ptrace_set_debugreg(6).
Kyle, you seem to be pushing all this to the edge with RR, any clues?
Since v2:
- fixed (user) INT1 / icebp detection
- some further cleanups
- two additional RFC patches
