did the zephyr kernel support the nested interrupt on all the supported arch?

hi all:

     i have reviewed the cortex-m arch about the interrupt flow, and found that cortex-m support max 255 interrupt entry and  it allows  interrupt with higher prio  preempted  another one with lower priority interrupt, 

i did not see other arch`s code but just want to know about, is this the feature of zephyr kernel? for the strong real-time feature? or  arch related?  

thanks for your  kindly support.
