Hi Oleg, can I have your acks or reviewed-by tags for 4-5-6 patches in the series, or there is something left to fix? 2016-08-31 16:59 GMT+03:00 Dmitry Safonov [off-list ref]:
Introduce new flags that defines which ABI to use on creating sigframe. Those flags kernel will set according to sigaction syscall ABI, which set handler for the signal being delivered. So that will drop the dependency on TIF_IA32/TIF_X32 flags on signal deliver. Those flags will be used only under CONFIG_COMPAT. Similar way ARM uses sa_flags to differ in which mode deliver signal for 26-bit applications (look at SA_THIRYTWO).
