Ingo, please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/oleg/misc uprobes/core
Based on tip:perf/uprobes
Denys found another nasty old bug in uprobes/x86: div, mul, shifts with
count in CL, and cmpxchg are not handled correctly.
Plus a couple of other minor fixes. Nobody acked the changes in x86/traps,
hopefully they are simple enough, and I believe that they make sense anyway
and allow to do more cleanups.
Denys Vlasenko (2):
uprobes/x86: Simplify rip-relative handling
uprobes/x86: Fix scratch register selection for rip-relative fixups
Oleg Nesterov (8):
uprobes: Add mem_cgroup_charge_anon() into uprobe_write_opcode()
x86/traps: Make math_error() static
x86/traps: Use SEND_SIG_PRIV instead of force_sig()
x86/traps: Introduce do_error_trap()
x86/traps: Introduce fill_trap_info(), simplify DO_ERROR_INFO()
x86/traps: Shift fill_trap_info() from DO_ERROR_INFO() to do_error_trap()
x86/traps: Kill DO_ERROR_INFO()
uprobes/x86: Fix the wrong ->si_addr when xol triggers a trap
