[PATCH v3 0/9] LoongArch: KVM: INTC: Enhancement about eiointc emulation

[Bibo Mao]

This series fix five issues about kernel eiointc emulation list as
follows:
  1. The first patch fixes type forced assignment issue.
  2. The second patch fixes interrupt route with physical cpu.
  3. The third patch disables update property num_cpu and feature
  4. The fourth patch adds validation check about num_cpu from user
     space.
  5. Overflow with array index when emulate register EIOINTC_ENABLE
     writing operation.

Also there is code cleanup with kernel eiointc emulation.

---
v2 ... v3:
  1. Add prefix INTC: in title of every patch.
  2. Fix array index overflow when emulate register EIOINTC_ENABLE
     writing operation.
  3. Add address alignment check with eiointc register access operation.

v1 ... v2:
  1. Add extra fix in patch 3 and patch 4, add num_cpu validation check
  2. Name of stat information keeps unchanged, only move it from VM stat
     to vCPU stat.
