This patchs add sections for IRQENTRY and SOFTIRQENTRY. Initially added by below kernel patch for all architecture, but missed in um.
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/?id=be7635e7287e0e8013af3c89a6354a9e0182594c
We need to add both sections because if someone has to use stackdepot feature for stacktrace and want to filter IRQ stack entries, it will break build for um.
Below patch is breaking build break for um. mm/page_owner: ignore everything below the IRQ entry point. V2:- https://lkml.org/lkml/2018/3/26/178 V3:- https://lkml.org/lkml/2018/3/27/357
