This series add generic eiointc 8 bytes access interface, so that 1/2/4/8
bytes access can use the generic 8 bytes access interface. It reduce
about 500 lines redundant code and make eiointc emulation driver
simpler than ever.
---
v5 ... v6:
1. Merge previous patch 5 & 6 into one, patch 7 & 10 into into one and
patch 12 and patch 13 into one.
2. Use sign extension with destination register for IOCSRRD.{B/H/W}
kernel emulation.
v4 ... v5
1. Rebase patch on latest kernel where bugfix of eiointc has been
merged.
2. Add generic eiointc 8 bytes access interface, 1/2/4/8 bytes access
uses generic 8 bytes access interface.
v3 ... v4:
1. Remove patch about enhancement and only keep bugfix relative
patches.
2. Remove INTC indication in the patch title.
3. With access size, keep default case unchanged besides 1/2/4/8 since
here all patches are bugfix
4. Firstly check return value of copy_from_user() with error path,
keep the same order with old patch in patch 4.
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.
