category: feature
bugzilla: 12807
CVE: NA

-------------------------------------------------

Now hns3 driver will be rebuild without changing any code:

[root@localhost hulk-4.19]# make -j64
  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h
  CC [M]  drivers/net/ethernet/hisilicon/hns3/kcompat.o
  CC [M]  drivers/net/ethernet/hisilicon/hns3/hns3pf/../kcompat.o
  LD [M]  drivers/net/ethernet/hisilicon/hns3/hns3.o
  LD [M]  drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge.o
  Building modules, stage 2.
  MODPOST 1400 modules
  CC      drivers/net/ethernet/hisilicon/hns3/hns3.mod.o
  CC      drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge.mod.o
  LD [M]  drivers/net/ethernet/hisilicon/hns3/hns3.ko
  LD [M]  drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge.ko

[root@localhost hulk-4.19]# make -j64
  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h
  CC [M]  drivers/net/ethernet/hisilicon/hns3/kcompat.o
  LD [M]  drivers/net/ethernet/hisilicon/hns3/hns3.o
  Building modules, stage 2.
  MODPOST 1400 modules
  CC      drivers/net/ethernet/hisilicon/hns3/hns3.mod.o
  CC      drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge.mod.o
  LD [M]  drivers/net/ethernet/hisilicon/hns3/hns3.ko
  LD [M]  drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge.ko

It's introduced by build kcompat.o both in hns3 and hns3/hns3pf.

kcompat.c provide pci_irq* relatived interfaces for driver
building in earlier version kernel. Now hulk-4.19 has these
interfaces, it can be removed to fix this problem.
