Subject: [PATCH v5 0/4] Provide core API for NMIs

Hi,

This patch series provides a way for irqchips to define some IRQs as NMIs.

Updating this series as it is needed for the arm64 pseudo-NMI[1] which we
are considering to merge.

Changes since v4[2]:
- Rebased on v5.0-rc4
- Modified comment for request_percpu_nmi() to detail
  the use of per CPU NMIs a bit more

Changes since v3[3]:
- Rebased on v4.20-rc2

Changes since v2[4]:
- Fix ARM build error reported by kbuild bot
- Fix documentation warnings reported by kbuild bot

Changes since v1[5]:
- Rebased to v4.19-rc1
- Fix some coding style issues

Changes since RFC[6]:
- Rebased to v4.18-rc6
- Remove disable_nmi, one should call disable_nmi_nosync instead
- Remove code related to affinity balancing from NMI functions
- Require PERCPU configuration for NMIs
